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…
Real-Time Dynamics in a (2+1)-D Gauge Theory: The Stringy Nature on a Superconducting Quantum Simulator
Jesús Cobos, Joana Fraxanet, César Benito +7
Understanding the confinement mechanism in gauge theories and the universality of effective string-like descriptions of gauge flux tubes remains a fundamental challenge in modern p…
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…
Spectroscopy of N=50 isotones with the valence-space density matrix renormalization group
A. Tichai, K. Kapás, T. Miyagi +4
The recently proposed combination of the valence-space in-medium similarity renormalization group (VS-IMSRG) with the density matrix renormalization group (DMRG) offers a scalable…
Attitude determination for nano-satellites -- I. Spherical projections for large field of view infrasensors
Kornél Kapás, Tamás Bozóki, Gergely Dálya +3
Due to the advancement of nano-satellite technology, CubeSats and fleets of CubeSats can form an alternative to high-cost large-size satellite missions with the advantage of extend…
