On symmetry-resolved generalized entropies
Fei Yan, Sara Murciano, Pasquale Calabrese +1
Symmetry-resolved entanglement, capturing the refined structure of quantum entanglement in systems with global symmetries, has attracted a lot of attention recently. In this manusc…
Duality defect in a deformed transverse-field Ising model
Fei Yan, Robert Konik, Aditi Mitra
Physical quantities with long lifetimes have both theoretical significance in the study of quantum many-body systems and practical implications for quantum technologies. In this ma…
Dynamical correlations and nonequilibrium sum rules in photodoped Hubbard ladders
E. Merhej, J. P. Hague, R. M. Konik +1
Using matrix product state techniques we study the nonequilibrium dynamical response of the half-filled Hubbard ladder when subject to an optical pump. Optical pumping offers a way…
Detecting Multipartite Entanglement Patterns using Single Particle Green's Functions
Rajesh K. Malla, Andreas Weichselbaum, Tzu-Chieh Wei +1
We present a protocol for detecting multipartite entanglement in itinerant many-body electronic systems using single particle Green's functions. To achieve this, we first establish…
Ultrafast Control of Magnetic Correlations in a Heisenberg Spin Ladder
Tianhao Ren, Robert M. Konik
We study the time-dependent response of a Heisenberg spin ladder subjected to a time-dependent square form variation of its rung spin exchange coupling. To do so, we employ a field…
Krylov Spaces for Truncated Spectrum Methodologies
Márton K. Lájer, Robert M. Konik
We propose herein an extension of truncated spectrum methodologies (TSMs), a non-perturbative numerical approach able to elucidate the low energy properties of quantum field theori…
