Numerical Hints for Dyon Condensation at via Wilson-'t Hooft Loops in Yang-Mills Theory
Hiromasa Watanabe, Issaku Kanamori, Okuto Morikawa +3
Yang-Mills theories at and are unitarily equivalent, but their periodicity has a nontrivial realization. Recent developments in generalized global symmetries sh…

Quantum decoherence in the Caldeira-Leggett model by the real-time path integral on a computer
Jun Nishimura, Hiromasa Watanabe
We propose first-principle calculations of an open system based on the real-time path integral formalism treating the environment as well as the system of our interest together on…

Quantum decoherence from complex saddle points
Jun Nishimura, Hiromasa Watanabe
Quantum decoherence is the effect that bridges quantum physics to well-understood classical physics. As such, it plays a crucial role in understanding the mysterious nature of quan…
