Summary: This study focuses on two-dimensional lattice SU(N-c) gauge theories with multiflavor scalar fields, investigating their properties in the zero-temperature limit and exploring the relation between the continuum limit and a symmetric space sigma model. The results confirm a conjecture regarding the nature of the continuum limit in such systems.

Summary: We thoroughly investigate the effects of SU(2) gauge on bilayer honeycomb lattice and discover a topological Lifshitz transition induced by the non-Abelian gauge potential. The topological Lifshitz transition is determined by the topologies of Fermi surfaces in momentum space. We also study the novel edge states of biased bilayer nanoribbon with gauge fluxes.

Summary: Coupling dynamical charges to gauge fields leads to non-local interactions and confinement potential, resulting in the formation of mesons and emergence of Luttinger liquids. Including nearest-neighbour (NN) interactions among charges stabilizes different Mott-insulating states. However, the rich phase diagrams in these models have not been fully explored and lack comprehensive theoretical explanation.

Summary: In this work, we investigate the impact of quantum quenching on the circuit complexity of quenched quantum field theory with weakly coupled quartic interactions. By using the invariant operator method under a perturbative framework, we compute the ground state of this system and provide analytical expressions for specific reference and target states. Additionally, we analytically compute the circuit complexity for the quenched and interacting field theory using a particular cost functional, and numerically estimate the circuit complexity with respect to the quench rate, dt, for two coupled oscillators. We also comment on the variation in circuit complexity for different coupling strengths, numbers of oscillators, and dimensions.

Summary: We present a solution for the nonequilibrium dynamics of an interacting disordered system by adapting the equilibrium dynamical mean-field theory and the equilibrium coherent potential approximation methods. Our approach uses the Kadanoff-Baym-Keldysh complex time contour to study the dynamics of interacting disordered systems away from equilibrium. We obtain the equilibrium density of states of the disordered interacting system and observe the effect of disorder on the relaxation of the system.

Our calculation correctly reproduces the entropy of the universal black hole that can be embedded in the holographically dual solution.

Summary: The study examines the fused SU(2) models and their corresponding BMW algebra, demonstrating the satisfaction of the BMW algebra by the five, six, and seven block models, suggesting its applicability to any model with more than two blocks. Using the Yang-Baxter equation, the algebra for the five block model is explicitly described, resulting in 19 additional non-trivial relations.

Summary: We study the persistent current in a system of SU(N) fermions with repulsive interaction. We find surprising effects, where spinons can be created and change the nature of the elementary flux quantum due to spin correlations, (effective) magnetic flux, and interaction. These changes have a dramatic impact on the persistent current and can detect quantum phase transitions.

Summary: In this study, a worldsheet description for the AdS(5) x S-5 string theory was proposed, dual to the large N, free N = 4 supersymmetric Yang-Mills theory. The worldsheet theory is a natural generalization of the tensionless string on AdS(3) x S-3 x T-4, with free field description and spectrally flowed sectors. By imposing a set of residual gauge constraints on the reduced oscillator Fock space, the physical spectrum of the string theory can be determined, reproducing the planar spectrum of single trace operators of the free supersymmetric Yang-Mills theory.

Summary: Mott materials allow the development of compact and power-efficient neuromorphic devices known as Mott neurons. However, the nature of the insulator-to-metal transition and the determination of the threshold voltage needed for the transition have not been fully understood. In this study, numerical simulations and experiments are used to investigate the filament incubation and formation process. The results show that both electronic and thermal effects contribute to filamentary growth, and the percolation of metallic filaments near the threshold exhibits stochastic behavior.

Summary: Fermionic Gaussian projected entangled pair states (PEPS) are used to describe ground states of noninteracting fermionic Hamiltonians. They can be efficiently studied and analyzed using both analytical and numerical methods. Recently, they have been used as a starting point for variational study of interacting lattice gauge theories, with the help of PEPS gauging mechanisms and sign-problem free variational Monte Carlo techniques. This work focuses on generalizing such states from two to three spatial dimensions, with a focus on spin representations and lattice rotations, which are crucial for studying nonperturbative lattice gauge theories with fermionic tensor network states.

Summary: We argue that the enhancement in the spin polarization of anti-hyperons compared to the polarization of the hyperons in noncentral relativistic heavy-ion collisions arises as a result of an interplay between the chiral and helical vortical effects. Assuming the spin vector dominance, we are able to describe the ratio of the (anti)hyperon spin polarizations obtained by the STAR group without fitting parameters.

Summary: The BEST Collaboration was formed to provide a theoretical framework for analyzing data from the Beam Energy Scan program at RHIC, with the goal of searching for a QCD critical point and manifestations of the chiral magnetic effect. Progress has been made in studying the equation of state, initial state models, hydrodynamic framework, freezeout prescriptions, and hadronic transport models over the past five years, with the challenge of integrating these components into a complete analysis framework.

Summary: This article discusses quantum entanglement in high energy hadron interactions and proposes a Haar trace of the light-cone density matrix to explain the emergence of entanglement entropy. The research reveals a direct relationship between entanglement entropy and parton structure functions, with maximal entanglement at large rapidity. The probabilistic parton model breaks down when controlling the phases of Fock state components.

Summary: Our paper explores the Chiral Magnetic Josephson junction (CMJ junction) composed of two non-centrosymmetric superconductors connected by a uniaxial ferromagnet. This structure shows an analog of the Chiral Magnetic Effect and has potential applications as a qubit with a tunable Hamiltonian. The CMJ junction offers a simpler and more robust architecture without the need for an offset magnetic flux, providing strong protection against noise from magnetization fluctuations.

Summary: The effect of uniform rotation on the equation of state of gluodynamics in lattice simulation was studied. The system was considered in the corotating reference frame, where rotation was modeled as an external gravitational field. The free energy of the system, for sufficiently slow rotation, was expanded as a power series in the angular velocity. The moment of inertia, calculated as the second-order coefficient of this expansion, was found to be negatively dependent on temperature up to T * ≈ 1.5T(c), the critical temperature of the confinement/deconfinement phase transition. The negative moment of inertia was attributed to the thermodynamic instability of the gluon plasma with respect to uniform rotation.

Summary: Using lattice simulations, we show that a strong magnetic field induces two consecutive crossover transitions in the electroweak sector of the vacuum, resulting in significant changes in the dynamics of the W bosons and Higgs particles. The first transition leads to the formation of inhomogeneous structures, indicating the presence of W and Z condensates pierced by vortices. These condensates give rise to exotic superconducting and superfluid properties. The second transition restores the electroweak symmetry. Such conditions can be found near magnetized black holes.

Summary: We present the results of numerical simulations on rotating Euclidean SU(3) Yang-Mills plasma and find the emergence of a spatially inhomogeneous confining-deconfining phase. Mapping the results to Minkowski spacetime suggests the existence of a new inhomogeneous phase with both confining and deconfinement phases. The inhomogeneous phase structure originates from the Tolman-Ehrenfest effect in a rotating medium. We also derive the Euclidean version of the Tolman-Ehrenfest law and discuss two temperature definitions in imaginary Euclidean rotation.

Summary: The helicity of free massless Dirac fermions is a conserved quantity in the classical equations of motion. The flow of helicity can be modeled by the helicity current, induced by vorticity in a medium with charge imbalance. This leads to new non-dissipative transport phenomena and the appearance of a new hydrodynamic excitation, the helical vortical wave.

Summary: The paper investigates the anomalous transport driven by a combination of shear, vorticity, and magnetic field. It finds characteristic charge correlations among the hadrons produced in heavy ion collisions. The proposed charge asymmetry of triangular flow is suggested as a signature of the anomalous transport, and the strength of the signal as well as the background is estimated using hydrodynamical model simulations. The signal-to-background ratio for the proposed observable is found to be favorable for experimental detection.

The introduction of a similarity gauge field leads to new effects, including instability in high-energy scalar particles, which are determined by the strength of the emergent similarity gauge field.

Summary: The study reveals the emergence of a non-Hermitian PT-symmetric ground state in the standard Hermitian Nambu-Jona-Lasinio model, characterized by a noncompact non-Hermitian symmetry group that can be spontaneously broken under different coupling regimes. The ground state exhibits inhomogeneity at strong coupling while maintaining spatial uniformity at weak coupling, lying between the PT-symmetric and PT-broken phases. Outside the chiral limit, the minimal NJL model does not have a stable non-Hermitian ground state.
