Dynamically generated quadrupole polarization using Floquet adiabatic evolution
Gonzalo Camacho, Christoph Karrasch, Roman Rausch
We investigate the nonequilibrium dynamics of the quantum spin chain subjected to a time-dependent external drive, where the driving frequency is adiabatically decreased as a…
Quantum spin spiral ground state of the ferrimagnetic sawtooth chain
Roman Rausch, Matthias Peschke, Cassian Plorin +2
The ferrimagnetic phase of the sawtooth chain with mixed ferromagnetic nearest-neighbour interactions and antiferromagnetic next-nearest-neighbour interactions (within the…
Minimal one-dimensional model of bad metal behavior from fast particle-hole scattering
Yan-Qi Wang, Roman Rausch, Christoph Karrasch +1
A strongly interacting plasma of linearly dispersing electron and hole excitations in two spatial dimensions (2D), also known as a Dirac fluid, can be captured by relativistic hydr…
