Critical correlations of Ising and Yang-Lee critical points from Tensor RG
Sankhya Basu, Vadim Oganesyan
We examine feasibility of accurate estimations of universal critical data using tensor renormalization group (TRG) algorithm introduced by Levin and Nave. Specifically, we compute…

Fisher zeros and persistent temporal oscillations in non-unitary quantum circuits
Sankhya Basu, Daniel P. Arovas, Sarang Gopalakrishnan +2
We present a quantum circuit with measurements and post-selection that exhibits a panoply of space- and/or time-ordered phases, from ferromagnetic order to spin-density waves to ti…

Dimensional crossover and the link between thermodynamics and dynamics: the case of Ising models at complex temperature
Sankhya Basu, Chris A. Hooley, Vadim Oganesyan
We study dimensional crossover in Ising systems at complex temperatures by comparing three types of system: the infinite isotropic 2D Ising model; the infinite anisotropic 2D Ising…
