Entanglement entropy of fermions in a strange metal
Santanu Singh, Surajit Bera, Chenyuan Li +2
The subsystem-size dependence of ground-state entanglement entropy and its crossover to thermal entropy as a function of temperature are well understood for one-dimensional (1D) ga…
Generation of Volume-Law Entanglement by Local-Measurement-Only Quantum Dynamics
Surajit Bera, Igor V. Gornyi, Sumilan Banerjee +1
Repeated local measurements typically have adversarial effects on entangling unitary dynamics, as local measurements usually degrade entanglement. However, recent works on measurem…
Sachdev-Ye-Kitaev Model in a Quantum Glassy Landscape
Surajit Bera, Jorge Kurchan, Marco Schiro
We study a generalization of `Yukawa models' in which Majorana fermions, interacting via all-to-all random couplings as in the Sachdev-Ye-Kitaev (SYK) model, are parametrically cou…
Non-Stabilizerness of Sachdev-Ye-Kitaev Model
Surajit Bera, Marco Schirò
We study the non-stabilizerness or quantum magic of the Sachdev-Ye-Kitaev () model, a prototype example of maximally chaotic quantum matter. We show that the Majorana spec…
