Summary: We present new findings on the non-equilibrium dynamics of quantum double dark-soliton states in the Lieb-Liniger model for one-dimensional Bose gas. Additionally, we demonstrate the exact finite-size scaling of the quasi-Bose-Einstein condensation (BEC) fraction, which characterizes the quasi-BEC in the weak coupling regime. Our results include the exact time evolution of the density profile, the derivation of a macroscopic quantum wave function, and the demonstration of scattering in the quantum double dark-soliton state. These observations suggest that quasi-BEC plays a significant role in the dynamics of quantum double dark-soliton states.

Summary: In this study, we investigate quantum double dark-solitons in the one-dimensional Bose gas by constructing corresponding quantum states in the Lieb-Liniger model. We introduce novel quantum states of a single dark soliton with a nonzero winding number and evaluate the density profile, square amplitude profile, and phase profile of the matrix element of the field operator. We also show that the mean-field product state is effective for the quantum states of double dark solitons.

Summary: Placing Mg-porphyrin molecules in a chiral optical cavity breaks time reversal symmetry, generating polariton ring currents with circular dichroism signals. The degeneracy of electronic states in the molecule is lifted by chiral polaritons, resulting in a signal one order of magnitude stronger than that induced by circularly polarized light. Enantiomer-selective photochemical processes in chiral optical cavities represent an intriguing future possibility.

Summary: The study focuses on the coupling effect of two concentric rings formed by bosonic condensates of exciton-polaritons, revealing the presence of stable Josephson vortices at different coupling strengths. The difference in mean angular momenta between the inner and outer rings is governed by the structure of the Josephson vortices, with the phase difference between the rings affecting their rotation behavior at varying coupling strengths.

Summary: The proposal introduces a method to generate and stabilize various nonlinear modes, such as dark, bright, dark-like, bright-like solitons, and vortices with m = 1 and m = 2, in a nonresonantly pumped exciton-polariton condensate by introducing spatially modulating pumping. Numerical simulations demonstrate that the balance between gain and loss can support the existence and stability of various nonlinear modes beyond just stable dark solitons in this scheme. This proposal may offer a pathway to generate, stabilize, and control nonlinear modes in the nonresonantly pumped exciton-polariton system.

Summary: Recent research has shown that the XX central spin model is integrable when a magnetic field perpendicular to the coupling plane is present. A large number of its eigenstates exhibit no correlation between the central spin and the spins it is coupled to. In this study, we have demonstrated that the integrability of the XX-central spin model remains even in the presence of a magnetic field oriented arbitrarily. Additionally, we have shown that dark states can still be found in the presence of an in-plane magnetic field if the coupling is strong enough. Finally, we have provided a simple explanation for this result and demonstrated its universality for various distributions of the coupling.

Summary: We introduce the concept of dark space phase transition, which may occur in open many-body quantum systems where irreversible decay, interactions, and quantum interference compete. Our study is based on a quantum many-body model and reveals a nonequilibrium phase transition within this dark space, featuring phenomena that cannot be encountered in classical systems. It has potential implications for technological applications, such as the collective encoding of quantum information.

Summary: The study focuses on the dynamical behaviors of a Bose-Einstein condensate with a dark soliton reflected from potential wells and barriers. The orientation angle and width of the potential change significantly affect the reflection probability, which can be described by a cosine function related to the angle. The reflection behavior differs for potential wells and barriers, with the dark soliton length and matter wave decay length playing key roles respectively. Time evolution of density profiles reveals distinct behaviors of matter waves in the region of potential variations during the reflection process.

Summary: Recent progress in the study of open quantum systems, coupled with the potential for commercially viable quantum technologies, has sparked significant interest. Many open quantum systems can be described by a non-Hermitian Hamiltonian, allowing for decay and dissipation to occur. In this paper, we discuss the universal dynamical scaling in the non-Hermitian O(N) model Hamiltonian after a sudden quench. We find that, despite the disruption of universality due to non-Hermiticity, the short-time scaling behavior can be restored, showcasing the compensation of dissipation by interaction effects and the emergence of a prethermal dark state where coherent many-body dynamics can still be observed.

Summary: In this study, we investigate the quantum dynamics of many-qubit systems strongly coupled to a quantized electromagnetic cavity field in the presence of decoherence and dissipation. The varying coupling strength of different qubits to the cavity field and the spread of their transition frequencies are taken into account. We derive compact analytic solutions for time-dependent quantum state amplitudes and observables for a broad class of open quantum systems using the stochastic Schrodinger equation approach. Depending on the initial quantum state preparation, we demonstrate that an ensemble of qubits can evolve into a rich variety of many-qubit entangled states with destructive or constructive interference between the qubits. Specifically, when only a small fraction of qubits are initially excited, the dissipation in a cavity will inevitably drive the system into robust dark states that are completely decoupled from the cavity and have much longer lifetimes than the decay time of the cavity field. Furthermore, we identify the conditions under which coherent coupling to the quantized cavity field overcomes the dephasing caused by a spread of transition frequencies in multiqubit systems and leads to the formation of a decoupled dark state.

Summary: We investigate the stability and controllability of one-dimensional bright and dark solitons, and two-dimensional bright solitons and vortices with different charges in a nonresonantly incoherent pumped exciton-polariton condensates. The introduction of a composite pumping can stabilize and modulate the profiles of these solitons. Our work demonstrates that the solitons obtained in this study are different from the ones in previous studies. This research may provide a way to modulate these solitons in the nonresonantly pumped exciton-polariton system.

Summary: This study investigates the Polariton induced conical intersection (PICI) created by coupling a diatomic molecule with quantized photon mode inside an optical cavity and the corresponding Berry Phase effects. The research shows that the Berry phase results in a phase-shift in the wavefunction after encircling the CI, while the geometric phase significantly influences the coupling between polaritonic states. These effects are further demonstrated through photo-fragment angular distribution.

Summary: Transition-metal dichalcogenides (TMDs) are layered materials with advantageous optoelectronic properties. In tungsten-based TMDs, dark excitons, which are optically inaccessible but represent the lowest excitonic states, can be formed by phonon scattering of photoexcited electrons under compressive strain in WS2. The emission and spectral properties of these dark excitons strongly depend on the local strain environment, making it a promising mechanism for strain sensing in two-dimensional semiconductors, with a gauge factor exceeding 104.

Summary: This study investigates the application of photoinduced electrochemiluminescence (PECL) in designing anti-Stokes systems that convert infrared (IR) into visible light without direct electrical contact. By studying different types of Si-based closed bipolar electrodes (BPEs), it was found that bright and long-lasting emission can be triggered by external bias and IR illumination. The study also demonstrates the control of onset bias and anti-Stokes shift by the employed electrochemiluminescent (ECL) system.

Summary: In this study, we investigated the performance of unprotected epitaxial GaAs/Si photoelectrodes during photocorrosion using structural, optical, and photoelectrochemical characterizations. We found that photoanodes consisting of a 1 μm thick GaAs epitaxially grown thin film on a low-cost Si substrate exhibited higher photocurrent than expensive commercial GaAs wafers. Through photoelectrochemical experiments under monochromatic excitation, we attributed the improved photocurrent to the dual-bandgap operation of the GaAs/Si photoelectrode, benefiting from both GaAs and Si photo-generated carriers. This finding opens up new possibilities for designing efficient and low-cost dual-bandgap photoelectrodes.
