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…

A comprehensive exploration of interaction networks reveals a connection between entanglement and network structure
Yoshiaki Horiike, Yuki Kawaguchi
Quantum many-body systems are typically studied assuming translational symmetry in the interaction network. Recent experimental advances in various platforms for quantum simulators…
