Comparing bipartite entropy growth in open-system matrix-product simulation methods
Guillermo Preisser, David Wellnitz, Thomas Botzung +1
The dynamics of one-dimensional quantum many-body systems is often numerically simulated with matrix-product states (MPSs). The computational complexity of MPS methods is known to…

Multifractality in the interacting disordered Tavis-Cummings model
Francesco Mattiotti, Jérôme Dubail, David Hagenmüller +3
We analyze the spectral and transport properties of the interacting disordered Tavis-Cummings model at half excitation filling. We demonstrate that a Poissonian level statistics co…
