Summary: We propose a mechanism for liquid formation in strongly correlated lattice systems by studying dipolar bosons in one-dimensional optical lattices as an example. We present a perturbative theory and validate it through simulations for the energetic and structural properties of the system's phases. We analyze the nonequilibrium properties and calculate the dynamic structure factor.

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: In this study, the authors demonstrate the precise tuning of one-dimensional confined potential at a homojunction of two single-layer 1T-NbSe2 islands using an in situ manipulation technique. The potential is found to be structurally sensitive and shows a nonmonotonic function of their interspacing. The electronic properties also change from a correlated insulator to a generalized one-dimensional Wigner crystallization with increasing confinement.

Summary: We investigate the equilibrium momentum distribution of strongly interacting one-dimensional mixtures of particles at zero temperature confined in a box potential. We find that the magnitude of the tail of the momentum distribution, characterized by 1/k4, is influenced not only by short-distance correlations but also by the presence of rigid walls. This additional contribution, which includes a k-independent term and an oscillating part, breaks the Tan relation and surprisingly encodes information on long-range spin correlations.

Summary: This study investigates many-body modes in gated one-dimensional wires and observes two parabolic dispersions associated with spin and charge excitations at high energies. It also discovers two additional one-dimensional replica modes that strengthen with decreasing wire length.

Summary: In this study, Ca2CuO3 nanosheets were used to explore the nonlinear optical performance and ultrafast carrier dynamics. The results showed that these nanosheets exhibited convertible nonlinear optical behavior and ultrashort relaxation time, indicating the excellent performance of one-dimensional strongly correlated cuprates.

Summary: The study investigates superconducting instability in quasi-1D disordered systems, modeling them as an array of Luttinger liquids with Josephson-type interchain coupling. The research utilizes renormalization-group analysis to search for parameters supporting superconductivity enhancement, finding that this phenomenon may occur within a specific range of parameters. This could potentially explain the experimental observation of disorder-enhanced superconductivity.

Summary: In this work, the nonadiabatic exchange-correlation (XC) potentials for strongly correlated materials in the context of time-dependent density-functional theory (TDDFT) are derived. The potentials are obtained for both the limits of strong and weak correlations, and the accuracy is tested by comparing with the dynamical mean-field theory (DMFT) solution. The possibility of obtaining a universal XC potential for intermediate interaction strengths is also discussed.
