Length-resolved Operator Growth and Path-Entropy Obstructions to Many-Body Localization
J. Sirker
For the disordered Ising chain with transverse and longitudinal fields, where couplings and fields are drawn from strictly positive distributions, Cao~\cite{Cao} has shown that the…

Pseudospectral phenomena and the origin of the non-Hermitian skin effect
J. Sirker
The non-Hermitian skin effect (NHSE), characterized by a macroscopic accumulation of eigenstates at the edge of a system with open boundaries, is often ascribed to a non-trivial po…

Comment on: "Scaling and Universality at Noisy Quench Dynamical Quantum Phase Transitions"
J. Sirker
In Ref. [1], dynamical quantum phase transitions (DQPTs) -- non-analyticities in the Loschmidt return rate at critical times -- are investigated in the presence of noise for a two-…
