A Recursive Method of the Stochastic State Selection for Quantum Spin Systems
Tomo Munehisa, Yasuko Munehisa
In this paper we propose the recursive stochastic state selection method, an extension of the recently developed stochastic state selection method in Monte Carlo calculations for q…
The Stochastic State Selection Method for Energy Eigenvalues in the Shastry-Sutherland Model
Tomo Munehisa, Yasuko Munehisa
We apply a recently developed stochastic method to the Shastry-Sutherland model on 4x4 and 8x8 lattices. This method, which we call the Stochastic State Selection Method here, enab…
A New Approach to Stochastic State selections in Quantum Spin Systems
Tomo Munehisa, Yasuko Munehisa
We propose a new type of Monte Carlo approach in numerical studies of quantum systems. Introducing a probability function which determines whether a state in the vector space survi…
Synchronized pulse control of decoherence
Chikako Uchiyama, Masaki Aihara
We present a new strategy for multipulse control over decoherence. When a two-level system interacts with a reservoir characterized by a specific frequency, we find that the decohe…
QCD event generators with next-to-leading order matrix-elements and parton showers
Y. Kurihara, J. Fujimoto, T. Ishikawa +4
A new method to construct event-generators based on next-to-leading order QCD matrix-elements and leading-logarithmic parton showers is proposed. Matrix elements of loop diagram as…
