Local optimization on pure Gaussian state manifolds
Bennet Windt, Alexander Jahn, Jens Eisert +1
We exploit insights into the geometry of bosonic and fermionic Gaussian states to develop an efficient local optimization algorithm to extremize arbitrary functions on these famili…
Central charges of aperiodic holographic tensor network models
Alexander Jahn, Zoltán Zimborás, Jens Eisert
Central to the AdS/CFT correspondence is a precise relationship between the curvature of an anti-de Sitter (AdS) spacetime and the central charge of the dual conformal field theory…
Majorana dimers and holographic quantum error-correcting codes
Alexander Jahn, Marek Gluza, Fernando Pastawski +1
Holographic quantum error-correcting codes have been proposed as toy models that describe key aspects of the AdS/CFT correspondence. In this work, we introduce a versatile framewor…
Complexity and entanglement for thermofield double states
Shira Chapman, Jens Eisert, Lucas Hackl +4
Motivated by holographic complexity proposals as novel probes of black hole spacetimes, we explore circuit complexity for thermofield double (TFD) states in free scalar quantum fie…
Equilibration towards generalized Gibbs ensembles in non-interacting theories
Marek Gluza, Jens Eisert, Terry Farrelly
Even after almost a century, the foundations of quantum statistical mechanics are still not completely understood. In this work, we provide a precise account on these foundations f…
