The role of classical periodic orbits in quantum many-body systems
Daniel Waltner, Boris Gutkin
Semiclassical methods have been applied very successfully to describe the nontrivial transition from the quantum to the classical regime in -particle or at least $…
Signatures of the interplay between chaos and local criticality on the dynamics of scrambling in many-body systems
Felix Meier, Mathias Steinhuber, Juan Diego Urbina +2
Fast scrambling, quantified by the exponential initial growth of Out-of-Time-Ordered-Correlators (OTOCs), is the ability to efficiently spread quantum correlations among the degree…
Winding Number Statistics of a Parametric Chiral Unitary Random Matrix Ensemble
Petr Braun, Nico Hahn, Daniel Waltner +2
The winding number is a concept in complex analysis which has, in the presence of chiral symmetry, a physics interpretation as the topological index belonging to gapped phases of f…
A Mapping between the Spin and Fermion Algebra
Felix Meier, Daniel Waltner, Petr Braun +1
We derive a formalism to express the spin algebra in a spin representation in terms of the algebra of fermionic operators that obey the Canonical Anti-co…
Localization in the Kicked Ising Chain
Daniel Waltner, Petr Braun
Determining the border between ergodic and localized behavior is of central interest for interacting many-body systems. We consider here the recently very popular spin-chain model…
Exact local correlations in kicked chains at light cone edges
Boris Gutkin, Petr Braun, Maram Akila +2
We show that local correlators in a wide class of kicked chains can be calculated exactly at light cone edges. Extending previous works on dual-unitary systems, the correlators bet…
