Probing the Chaos to Integrability Transition in Double-Scaled SYK
Sergio E. Aguilar-Gutierrez, Rathindra Nath Das, Johanna Erdmenger +1
We investigate how a thermodynamical first-order phase transition affects the dynamical chaotic behaviour of a given model. To this effect, we analyze the model of Berkooz, Brukner…
Torsional Hall Viscosity of Massive Chern Insulators: Magnetic Field and Momentum Deformations
Ioannis Matthaiakakis, Weizhen Jia, Raffael L. Klees +7
This work focuses on the non-dissipative, parity-odd spin transport of -dimensional relativistic electrons, generated by torsion, and the torsional Hall viscosity $ζ_{\rm H}…
Entropy Measures for Transition Matrices in Random Systems
Zhaohui Chen, Rene Meyer, Zhuo-Yu Xian
A transition matrix can be constructed through the partial contraction of two given quantum states. We analyze and compare four different definitions of entropy for transition matr…
Krylov space approach to Singular Value Decomposition in non-Hermitian systems
Pratik Nandy, Tanay Pathak, Zhuo-Yu Xian +1
We propose a tridiagonalization approach for non-Hermitian random matrices and Hamiltonians using singular value decomposition (SVD). This technique leverages the real and non-nega…
Wormhole-induced effective coupling in SYK chains
Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +2
Inhomogeneous quantum chains have recently been considered in the context of developing novel discrete realizations of holographic dualities. To advance this programme, we explore…
