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…

Monte Carlo studies of quantum cosmology by the generalized Lefschetz thimble method

Chien-Yu Chou, Jun Nishimura

Quantum cosmology aims at elucidating the beginning of our Universe. Back in early 80's, Vilenkin and Hartle-Hawking put forward the "tunneling from nothing" and "no boundary" prop…
