Criteria for Feasible Monte Carlo Stochastic Simulations of Bosonic Markovian Open Quantum Dynamics
Toma Yoneya, Kazuya Fujimoto, Yuki Kawaguchi
The Monte Carlo sampling of the stochastic differential equations (SDEs) based on the quasiprobability distribution function, such as the Glauber--Sudarshan P, Wigner, and Husimi Q…
Path-Integral Formulation of Bosonic Markovian Open Quantum Dynamics with Monte Carlo stochastic trajectories using the Glauber-Sudarshan P, Wigner, and Husimi Q Functions and Hybrids
Toma Yoneya, Kazuya Fujimoto, Yuki Kawaguchi
The Monte Carlo (MC) trajectory sampling of stochastic differential equations (SDEs) based on the quasiprobabilities, such as the Glauber-Sudarshan P, Wigner, and Husimi Q function…
An Equation of State for Turbulence in the Gross-Pitaevskii model
Gevorg Martirosyan, Kazuya Fujimoto, Nir Navon
We report the numerical observation of a far-from-equilibrium equation of state (EOS) in the Gross-Pitaevskii model. We first show that the momentum distribution of the turbulent c…
Path-Integral Formulation of Truncated Wigner Approximation for Bosonic Markovian Open Quantum Systems
Toma Yoneya, Kazuya Fujimoto, Yuki Kawaguchi
The truncated Wigner approximation (TWA) enables us to investigate bosonic quantum many-body dynamics, including open quantum systems described by the Gorini-Kossakowski-Sudarshan-…
