Summary: At the limit of infinite confinement strength, the ground state of a system containing two interacting fermions or bosons in harmonic confinement remains strongly correlated. The natural orbitals of this system exhibit peculiar properties, such as nonzero collective occupancies for all angular momenta and a relationship with eigenfunctions and eigenvalues of a zero-energy Schrodinger equation with an attractive Gaussian potential. These properties have implications for the decay behavior and energy contributions of the system.

Summary: A goal of modern condensed-matter physics is to search for states of matter with emergent properties and desirable functionalities. By controlling light-matter interactions, it is possible to manipulate and synthesize strongly correlated quantum matter, leading to phenomena like photon-mediated superconductivity, cavity fractional quantum Hall physics, and optically driven topological phenomena.

Summary: Guiding many-body systems to desired states is a central challenge of modern quantum science. In this study, low-entropy quantum fluids of light were constructed in a Bose-Hubbard circuit using particle-by-particle assembly and adiabatic preparation. The results show the formation of strongly correlated fluids with entanglement and avoidance interactions.

Summary: The Anequation-of-motion block-correlated coupled cluster method based on the generalized valence bond wave function (EOM-GVB-BCCC) is proposed to describe low-lying excited states for strongly correlated systems. The EOM-GVB-BCCC2b method, which includes up to two-pair correlation, has been successfully implemented and tested for several strongly correlated systems. The results of EOM-GVB-BCCC2b for a water hexamer and four conjugated diradical species are consistent with the density matrix renormalization group (DMRG) results.

Summary: The applicability of using entanglement witnesses and operator-specific quantum bounds to diagnose many-body entanglement in condensed matter systems is investigated. The study focuses on detecting entangled states in quantum systems driven out of equilibrium. The dynamics of a fermion chain undergoing a time-dependent change of the Coulomb interaction is studied using the multipartite entanglement witness, the quantum Fisher information. The results show that the quantum Fisher information can witness distinct signatures of multipartite entanglement both near and far from equilibrium, and these signatures are robust against decoherence. The findings have implications for probing entanglement in light-driven quantum materials with time-resolved optical and x-ray scattering methods.

Summary: The study found that local orbital fluctuations are significantly enhanced in the superconducting state of A(3)C(60) fulleride superconductors, providing the pairing glue and supporting the spin/orbital freezing theory of unconventional superconductivity. Additionally, the results are consistent with the experimentally observed universal relation between the gap energy and local susceptibility in a wide range of unconventional superconductors.

Summary: We have developed a new machine-learning model to predict mutual information for strongly correlated systems, which is a complex quantity but carries important information about the correlation structure. In this study, we replaced expensive DMRG calculations with our newly trained ML model to predict mutual information. We demonstrated the model's performance in determining correlation structure and orbital ordering for accurate DMRG calculations, comparing the results with those obtained from accurate DMRG calculations.

Summary: Composite fermions can form bubbles that order into a lattice. The re-entrance of the fractional quantum Hall effect is associated with a bubble phase with two composite fermion quasiparticles per bubble. This observation demonstrates the existence of a new class of strongly correlated topological phases driven by clustering and charge ordering of emergent quasiparticles.

Summary: Efficient catalysts are crucial for the oxygen evolution reaction (OER) in various electrochemical processes. In this study, cobalt tetrahedra stabilized on the surface of YBCo4O7 material were found to efficiently catalyze OER. The surface of YBaCo4O7 showed resilience towards structural amorphization during OER, and the dual corner-shared cobalt tetrahedra acted as active sites for the reaction.

Summary: Magnetic alloys are crucial for efficient catalysts in fuel cells. Spin manipulation of magnetic materials has been found to enhance the kinetics of oxygen reduction reaction (ORR), bridging the gap between strongly correlated materials physics and heterogeneous catalysis. In this study, structurally ordered Pt3Co nanowires are synthesized and display superior ORR catalytic activity and higher tolerance to carbon monoxide compared to other catalysts. Density functional theory calculations reveal that the ordered Pt3Co(111) surface exhibits better selectivity and lower activation energy for ORR compared to disordered Pt3Co(111) and Pt(111) surfaces.
