DOI: 10.1088/1367-2630/aa93a5
Abstract: We numerically explore the many body localization (MBL) transition through the lens of the entanglement spectrum. While a direct transition from localization to thermalization is believed to be obtained in the thermodynamic limit (the exact… read more here.

DOI: 10.1088/1751-8121/ac5529
Abstract: The statistical mechanics characterization of finite subsystems embedded in an infinite system is a fundamental question of quantum physics. Nevertheless, a full closed form for all required entropic measures does not exist in the general… read more here.

Abstract: The entanglement spectrum is a useful tool to study topological phases of matter, and contains valuable information about the ground state of the system. Here, we study its properties for free non-Hermitian systems for both… read more here.

DOI: 10.1103/physrevd.99.026008
Abstract: A sort of planar tensor networks with tensor constraints is investigated as a model for holography. We study the greedy algorithm generated by tensor constraints and propose the notion of critical protection (CP) against the… read more here.

DOI: 10.1103/physrevlett.121.250601
Abstract: We unveil the stable (d+1)-dimensional topological structures underlying the quench dynamics for all of the Altland-Zirnbauer classes in d=1 dimension, and we propose to detect such dynamical topology from the time evolution of entanglement spectra.… read more here.

DOI: 10.1134/s0021364017230035
Abstract: The entanglement spectrum of superfluid phases of 3He, the 3D B-phase and the planar phase in two dimensions, has been analyzed. The wavefunctions of the low-lying eigenstates, including Majorana zero modes, as well as the… read more here.
