Neural-network quantum states for solving few-body problems: application to Efimov physics
Sora Yokoi, Shimpei Endo, Hiroki Saito
Neural-network quantum states have recently emerged as a powerful method for solving quantum many-body problems, with notable successes in lattice systems. Here, we extend this app…
Dynamics of entanglement asymmetry for space-inversion symmetry of free fermions on honeycomb lattices
Ryogo Hara, Shimpei Endo, Shion Yamashika
We study the entanglement asymmetry for the space-inversion symmetry of free fermions on a two-dimensional honeycomb lattice with an on-site energy imbalance between the two sublat…
Quantum Fisher Information as a Measure of Symmetry Breaking in Quantum Many-Body Systems
Shion Yamashika, Shimpei Endo, Hiroyasu Tajima
Symmetry breaking underlies diverse phenomena from phase transitions in condensed matter to fundamental interactions in gauge theories. Despite many proposed indicators, a general…
Topological phases and edge modes of an uneven ladder
Wen-Chuang Shang, Yi-Ning Han, Shimpei Endo +1
We investigate the topological properties of a two-chain quantum ladder with uneven legs, i.e. the two chains differ in their periods by a factor of two. Such an uneven ladder pres…
Dynamical invariant based shortcut to equilibration in open quantum systems
Mohamed Boubakour, Shimpei Endo, Thomás Fogarty +1
We propose using the dynamical invariant also known as the Lewis-Riesenfeld invariant, to speed-up the equilibration of a driven open quantum system. This allows us to reverse engi…
