Many-body topology in parity-preserving tensor networks
Maksimilian Usoltcev, Nguyen Hanh Dung, Carolin Wille +2
Planar parity-preserving tensor networks (ppTNs) admit a fermionic formulation in which the Gaussian, efficiently contractible limit is deformed by local interactions. We investiga…
Theory of Anderson localization on the hyperbolic plane
Alexander Altland, Tobias Micklitz, Devasheesh Sharma +2
The two-dimensional hyperbolic plane, , is an unusual system in that dimensionality changes with scale: locally two-dimensional and planar at short distances, but eff…
The chiral SYK model in three-dimensional holography
Alexander Altland, Dmitry Bagrets, Nele Callebaut +1
A celebrated realization of the holographic principle posits an approximate duality between the -dimensional quantum mechanical SYK model and two-dimensional Jackiw-Teitelbo…
A minimal tensor network beyond free fermions
Carolin Wille, Maksimilian Usoltcev, Jens Eisert +1
This work proposes a minimal model extending the duality between classical statistical spin systems and fermionic systems beyond the case of free fermions. A Jordan-Wigner transfor…
Dynamics of measured many-body quantum chaotic systems
A. Altland, M. Buchhold, S. Diehl +1
We consider the dynamics of continuously measured many-body chaotic quantum systems. Focusing on the observable of state purification, we analytically describe the limits of strong…
Echo spectroscopy of Anderson localization
T. Micklitz, C. A. Müller, A. Altland
We propose a conceptually new framework to study the onset of Anderson localization in disordered systems. The idea is to expose waves propagating in a random scattering environmen…
Strong Anderson localization in cold atom quantum quenches
T. Micklitz, C. A. Müller, A. Altland
Signatures of strong Anderson localization in the momentum distribution of a cold atom cloud after a quantum quench are studied. We consider a quasi one-dimensional cloud initially…
Semiclassical theory of chaotic quantum resonances
T. Micklitz, A. Altland
States supported by chaotic open quantum systems fall into two categories: a majority showing instantaneous ballistic decay, and a set of quantum resonances of classically vanishin…
