Universality classes of spin transport in one-dimensional isotropic magnets: the onset of logarithmic anomalies
Jacopo De Nardis, Marko Medenjak, Christoph Karrasch +1
We report a systematic study of finite-temperature spin transport in quantum and classical one-dimensional magnets with isotropic spin interactions, including both integrable and n…
Superdiffusive transport of energy in one-dimensional metals
Vir B. Bulchandani, Christoph Karrasch, Joel E. Moore
Metals in one spatial dimension are described at the lowest energy scales by the Luttinger liquid theory. It is well understood that this free theory, and even interacting integrab…
Anomalous spin diffusion in one-dimensional antiferromagnets
Jacopo De Nardis, Marko Medenjak, Christoph Karrasch +1
The problem of characterizing low-temperature spin dynamics in antiferromagnetic spin chains has so far remained elusive. We reinvestigate it by focusing on isotropic antiferromagn…
Subdiffusive front scaling in interacting integrable models
Vir B. Bulchandani, Christoph Karrasch
We show that any interacting integrable model possesses a class of initial states for which the leading corrections to ballistic transport are subdiffusive rather than diffusive. T…
Loschmidt-amplitude wave function spectroscopy and the physics of dynamically driven phase transitions
D. M. Kennes, C. Karrasch, A. J. Millis
We introduce the Loschmidt amplitude as a powerful tool to perform spectroscopy of generic many-body wave functions and use it to interrogate the wave function obtained after rampi…
Controlling Dynamical Quantum Phase Transitions
D. M. Kennes, D. Schuricht, C. Karrasch
We study the dynamics arising from a double quantum quench where the parameters of a given Hamiltonian are abruptly changed from being in an equilibrium phase A to a different phas…
