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…
Tensor network models of AdS/qCFT
Alexander Jahn, Zoltán Zimborás, Jens Eisert
The study of critical quantum many-body systems through conformal field theory (CFT) is one of the pillars of modern quantum physics. Certain CFTs are also understood to be dual to…
