Operator Delocalization in Quantum Networks
Joonho Kim, Jeff Murugan, Jan Olle +1
We investigate the delocalization of operators in non-chaotic quantum systems whose interactions are encoded in an underlying graph or network. In particular, we study how fast ope…
Neural Networks as Universal Probes of Many-Body Localization in Quantum Graphs
Cameron Beetar, Jeff Murugan, Dario Rosa
We show that a neural network, trained on the entanglement spectra of a nearest neighbor Heisenberg chain in a random transverse magnetic field, can be used to efficiently study th…
Quantum Charging Advantage Cannot Be Extensive Without Global Operations
Ju-Yeon Gyhm, Dominik Šafránek, Dario Rosa
Quantum batteries are devices made from quantum states, which store and release energy in a fast and efficient manner, thus offering numerous possibilities in future technological…
Replica Symmetry Breaking and Phase Transitions in a PT Symmetric Sachdev-Ye-Kitaev Model
Antonio M. García-García, Yiyang Jia, Dario Rosa +1
We show that the low temperature phase of a conjugate pair of uncoupled, quantum chaotic, nonhermitian systems such as the Sachdev-Ye-Kitaev (SYK) model or the Ginibre ensemble of…
