Distinguishing thermal versus quantum annealing using probability-flux signatures across interaction networks
Yoshiaki Horiike, Yuki Kawaguchi
Simulated annealing provides a heuristic solution to combinatorial optimization problems. The cost function of a problem is mapped onto the energy function of a physical many-body…

Dynamical axion fields coupled with one-dimensional spinless fermions
Yuto Hosogi, Koichiro Furutani, Yuki Kawaguchi
We investigate coupled dynamics of spinless fermions on a one-dimensional lattice and spins on the links. When the hopping integral and the on-site potential of the fermions depend…

Nonequilibrium quantum states emerging from flippable spins in random networks
Yoshiaki Horiike, Yuki Kawaguchi
Recent advances in programmable quantum simulators have enabled the realization of irregular interaction networks, which natural crystal lattices cannot provide, together with time…
