Updated Core Libraries of the ALPS Project
Markus Wallerberger, Sergei Iskakov, Alexander Gaenko +13
The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice…
Parallel loop cluster quantum Monte Carlo simulation of quantum magnets based on global union-find graph algorithm
Synge Todo, Haruhiko Matsuo, Hideyuki Shitara
A large-scale parallel loop cluster quantum Monte Carlo simulation is presented. On 24,576 nodes of the K computer, one loop cluster Monte Carlo update of the world-line configurat…
Search for Common Minima in Joint Optimization of Multiple Cost Functions
Daiki Adachi, Naoto Tsujimoto, Ryosuke Akashi +2
We present a novel optimization method, named the Combined Optimization Method (COM), for the joint optimization of two or more cost functions. Unlike the conventional joint optimi…
Fast algorithm for generating random bit strings and multispin coding for directed percolation
Hiroshi Watanabe, Satoshi Morita, Synge Todo +1
We present efficient algorithms to generate a bit string in which each bit is set with arbitrary probability. By adopting a hybrid algorithm, i.e., a finite-bit density approximati…
Localized Mode and Nonergodicity of a Harmonic Oscillator Chain
Fumihiro Ishikawa, Synge Todo
We present a simple and microscopic physical model that breaks the ergodicity. Our model consists of coupled classical harmonic oscillators, and the motion of the tagged particle o…
Optical Bistability in a Low Photon-Density Regime
Tatsuhiko Shirai, Synge Todo, Hans de Raedt +1
We give a microscopic description of the optical bistability, where the transmission coefficient has two different values as a function of input light intensity, and the system exh…
