Kibble-Zurek mechanism from different angles: The transverse XY model and subleading scalings

Björn Ladewig, Steven Mathey, Sebastian Diehl

The Kibble-Zurek mechanism describes the saturation of critical scaling upon dynamically approaching a phase transition. This is a consequence of the breaking of adiabaticity due t…

Dynamic renormalization group theory for open Floquet systems

Steven Mathey, Sebastian Diehl

We develop a comprehensive Renormalization Group (RG) approach to criticality in open Floquet systems, where dissipation enables the system to reach a well-defined Floquet steady s…

Activating critical exponent spectra with a slow drive

Steven Mathey, Sebastian Diehl

We uncover an aspect of the Kibble--Zurek phenomenology, according to which the spectrum of critical exponents of a classical or quantum phase transition is revealed, by driving th…

Absence of Criticality in the Phase Transitions of Open Floquet Systems

Steven Mathey, Sebastian Diehl

We address the nature of phase transitions in periodically driven systems coupled to a bath. The latter enables a synchronized non-equilibrium Floquet steady state at finite entrop…

KPZ equation with short-range correlated noise: emergent symmetries and non-universal observables

Steven Mathey, Elisabeth Agoritsas, Thomas Kloss +2

We investigate the stationary-state fluctuations of a growing one-dimensional interface described by the KPZ dynamics with a noise featuring smooth spatial correlations of characte…

Functional renormalisation approach to driven dissipative dynamics

Steven Mathey

I investigate stationary scaling states of Burgers' and Gross-Pitaevskii equations (GPE). The path integral representation of the steady state of the stochastic Burgers equation is…

Anomalous scaling at non-thermal fixed points of Burgers' and Gross-Pitaevskii turbulence

Steven Mathey, Thomas Gasenzer, Jan M. Pawlowski

Scaling in the dynamical properties of complex many-body systems has been of strong interest since turbulence phenomena became the subject of systematic mathematical studies. In th…

Decoherence in an exactly solvable qubit model with initial qubit-environment correlations

V. G. Morozov, S. Mathey, G. Röpke

We study a model of dephasing (decoherence) in a two-state quantum system (qubit) coupled to a bath of harmonic oscillators. An exact analytic solution for the reduced dynamics of…
