Diversifying time evolution of matrix product states using BUGs
Kornél Kapás, Dominik Sulz, Charlotte Verhoeven +3
Time evolution of tensor-network states is a central tool for studying nonequilibrium dynamics in strongly correlated quantum systems. In the past decade, using the time-dependent…
Block entropy area based non-local fermionic mode optimization with gradient disentanglers
Miklós Antal Werner, Gero Friesecke, Andor Menczer +2
We introduce a systematic block entropy area based mode optimization algorithm for many-body quantum states of interacting fermions represented by matrix product states. From the g…
Global fermionic mode optimization via swap gates
Gero Friesecke, Miklós Antal Werner, Kornél Kapás +2
An optimal choice of single-particle modes leads to an optimal tensor network-based compression of the many-body wave function for systems of indistinguishable particles, which com…
Loss-induced quantum information jet in an infinite temperature Hubbard chain
Patrik Penc, Cătălin Paşcu Moca, Örs Legeza +3
Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly i…
Two dimensional quantum lattice models via mode optimized hybrid CPU-GPU density matrix renormalization group method
Andor Menczer, Kornél Kapás, Miklós Antal Werner +1
We present a hybrid numerical approach to simulate quantum many body problems on two spatial dimensional quantum lattice models via the non-Abelian ab initio version of the density…
A simple electronic ladder model harboring parafermions
Botond Osváth, Gergely Barcza, Örs Legeza +2
Parafermions are anyons with the potential for realizing non-local qubits that are resilient to local perturbations. Compared to Majorana zero modes, braiding of parafermions imple…
