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…
Entanglement and Complexity of Purification in (1+1)-dimensional free Conformal Field Theories
Hugo A. Camargo, Lucas Hackl, Michal P. Heller +3
Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum field theory as a partial trace is necessarily a challenging task. Nevertheless, such puri…
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…
Entanglement of Purification in Many Body Systems and Symmetry Breaking
Arpan Bhattacharyya, Alexander Jahn, Tadashi Takayanagi +1
We study the entanglement of purification (EoP), a measure of total correlation between two subsystems and , for free scalar field theory on a lattice and the transverse-fie…
