DOI: 10.1007/s00220-020-03760-x
Abstract: We study a class of close-packed dimer models on the square lattice, in the presence of small but extensive perturbations that make them non-determinantal. Examples include the 6-vertex model close to the free-fermion point, and… read more here.

DOI: 10.1007/s11425-015-0270-9
Abstract: This paper studies multi-solitons of non-integrable generalized Davey-Stewartson system in the elliptic-elliptic case. By extending the method for constructing multi-solitons of non-integrable nonlinear Schrödinger equations and systems developed by Martel et al. to the present… read more here.

DOI: 10.1088/1751-8121/ab2ddb
Abstract: The Loschmidt echo is investigated to track the effect of the local QDP. It is also quite sensitive to whether the background dynamics is integrable or not. For the integrable case, viz. the Heisenberg model,… read more here.

DOI: 10.1103/physrevb.100.115150
Abstract: How quantum information is scrambled in the global degrees of freedom of non-equilibrium many-body systems is a key question to understand local thermalization. Here we propose that the scaling of the mutual information between two… read more here.
