Localization and delocalization of fermions in a background of correlated spins
Tetsuya Takaishi, Kazuhiko Sakakibara, Ikuo Ichinose +1
We study the (de)localization phenomena of one-component lattice fermions in spin backgrounds. The O(3) classical spin variables on sites fluctuate thermally through the ordinary n…
Neural Network for Quantum Brain Dynamics: 4D CP+U(1) Gauge Theory on Lattice and its Phase Structure
Shinya Sakane, Takashi Hiramatsu, Tetsuo Matsui
We consider a system of two-level quantum quasi-spins and gauge bosons put on a 3+1D lattice. As a model of neural network of the brain functions, these spins describe neurons quan…
Atomic quantum simulation of a three-dimensional U(1) gauge-Higgs model
Yoshihito Kuno, Shinya Sakane, Kenichi Kasamatsu +2
In this paper, we study theoretically atomic quantum simulations of a U(1) gauge-Higgs model on a three-dimensional (3D) spatial lattice by using an extended Bose-Hubbard model wit…
Quantum simulation of -dimensional U(1) gauge-Higgs model on a lattice by cold Bose gases
Yoshihito Kuno, Shinya Sakane, Kenichi Kasamatsu +2
We present a theoretical study of quantum simulations of -dimensional U(1) lattice gauge-Higgs models, which contain a compact U(1) gauge field and a Higgs matter field, by…
Real time dynamics and proposal for feasible experiments of lattice gauge-Higgs model simulated by cold atoms
Yoshihito Kuno, Kenichi Kasamatsu, Yoshiro Takahashi +2
Lattice gauge theory has provided a crucial non-perturbative method in studying canonical models in high-energy physics such as quantum chromodynamics. Among other models of lattic…
Lattice Gauge Theory for Condensed Matter Physics: Ferromagnetic Superconductivity as its Example
Ikuo Ichinose, Tetsuo Matsui
Recent theoretical studies of various strongly-correlated systems in condensed matter physics reveal that the lattice gauge theory(LGT) developed in high-energy physics is quite a…
