Distinguishing dynamical quantum criticality through local fidelity distances
Ruchira V Bhat, Soumya Bera
Using local quantum fidelity distances, we study the dynamical quantum phase transition in integrable and non-integrable one-dimensional Ising chains. Unlike the Loschmidt echo, th…

High-temperature spin dynamics in the Heisenberg chain: Magnon propagation and emerging KPZ-scaling in the zero-magnetization limit
Felix Weiner, Peter Schmitteckert, Soumya Bera +1
The large-scale dynamics of quantum integrable systems is often dominated by ballistic modes due to the existence of stable quasi-particles. We here consider as an archetypical exa…

Dynamical quantum phase transitions in Weyl semimetals
Aritra Lahiri, Soumya Bera
The quench dynamics in type-I inversion symmetric Weyl semimetals (WSM) are explored in this work which, due to the form of the Hamiltonian, may be readily extended to two-dimensio…
