Local Thermalization of SU(2) Lattice Gauge Fields on Quantum Computers
Jiunn-Wei Chen, Yu-Ting Chen, Ghanashyam Meher +3
We simulate the local thermalization dynamics for minimally truncated SU(2) pure gauge theory on linear plaquette chains with up to 151 plaquettes using IBM quantum computers. We s…
Anomalous resonance in Weyl semimetals: A holographic study of non-linear effects
Maximilian Gaschler, Andreas Schäfer, Sebastian Waeber
We consider hairy, magnetic black brane solutions to Einstein-Maxwell-Chern-Simons-dilaton theory with full back-reaction of the scalar and gauge fields and compute the time evolut…
The Magic Barrier before Thermalization
Lukas Ebner, Berndt Müller, Andreas Schäfer +3
We investigate the time dependence of anti-flatness in the entanglement spectrum, a measure for non-stabilizerness and lower bound for non-local quantum magic resource, on a subsys…
Two Splits, Three Ways: Advances in Double Splitting Quenches
Joseph Dominicus Lap, Berndt Müller, Andreas Schäfer +1
In this work we introduce a method for calculating holographic duals of BCFTs with more than two boundaries. We apply it to calculating the dynamics of entanglement entropy in a 1+…

Lukas Ebner, Berndt Müller, Andreas Schäfer +2
We present preliminary numerical evidence for the hypothesis that the Hamiltonian SU(2) gauge theory discretized on a lattice obeys the Eigenstate Thermalization Hypothesis (ETH).…

Georg Bergner, Norbert Bodendorfer, Masanori Hanada +5
We study the confinement/deconfinement transition in the D0-brane matrix model (often called the BFSS matrix model) and its one-parameter deformation (the BMN matrix model) numeric…
Holographic Kolmogorov-Sinai entropy and the quantum Lyapunov spectrum
Georg Maier, Andreas Schäfer, Sebastian Waeber
In classical chaotic systems the entropy, averaged over initial phase space distributions, follows an universal behavior. While approaching thermal equilibrium it passes through a…
