DOI: 10.1088/1742-5468/add1cd
Abstract: Some lattice models having two conservation laws may display an equilibrium phase transition from a homogeneous (positive temperature—PT) to a condensed (negative temperature) phase, where a finite fraction of the energy is localized in a… read more here.

DOI: 10.1103/7bc3-3jz9
Abstract: We focus on the infinite temperature dynamical spin structure factor of the asymmetric Hatsugai-Kohmoto model, the relative of the asymmetric Hubbard model. It is characterized by distinct single particle energies for the two spin species,… read more here.

DOI: 10.1103/physrevb.101.094304
Abstract: We consider the class of dual-unitary quantum circuits in 1 + 1 dimensions and introduce a notion of “solvable” matrix product states (MPSs), defined by a specific condition which allows us to tackle their time… read more here.

DOI: 10.1103/physrevb.110.l100304
Abstract: We study a chaotic particle-conserving kinetically constrained model, with a single parameter which allows us to break reflection symmetry. Through extensive numerical simulations we find that the domain wall state shows a variety of dynamical… read more here.

DOI: 10.1103/physrevlett.124.130602
Abstract: Dynamical universality is the observation that the dynamical properties of different systems might exhibit universal behavior that are independent of the system details. In this Letter, we study the longtime dynamics of a one-dimensional noisy… read more here.

DOI: 10.1103/physrevlett.127.230603
Abstract: Studies of disordered spin chains have recently experienced a renewed interest, inspired by the question to which extent the exact numerical calculations comply with the existence of a many-body localization phase transition. For the paradigmatic… read more here.
