Quantum Monte Carlo Methods: Algorithms for Lattice Models

- J. Gubernatis, N. Kawashima, P. Werner
- Physics
- 24 June 2016

Featuring detailed explanations of the major algorithms used in quantum Monte Carlo simulations, this is the first textbook of its kind to provide a pedagogical overview of the field and its… Expand

Scaling relation for dangerously irrelevant symmetry-breaking fields

- T. Okubo, Kosei Oshikawa, Hiroshi Watanabe, N. Kawashima
- Physics
- 7 November 2014

We propose a scaling relation for critical phenomena in which a symmetry-breaking field is dangerously irrelevant. We confirm its validity on the six-state clock model in three and four dimensions by… Expand

Clues and criteria for designing a Kitaev spin liquid revealed by thermal and spin excitations of the honeycomb iridate Na 2 IrO 3

- Youhei Yamaji, T. Suzuki, Takuto Yamada, S. Suga, N. Kawashima, M. Imada
- Physics
- 21 January 2016

Contrary to the original expectation, ${\mathrm{Na}}_{2}{\mathrm{IrO}}_{3}$ is not a Kitaev's quantum spin liquid (QSL) but shows a zigzag-type antiferromagnetic order in experiments. Here, we… Expand

Strong-coupling expansion for the momentum distribution of the Bose-Hubbard model with benchmarking against exact numerical results

- J. Freericks, H. R. Krishnamurthy, Yasuyuki Kato, N. Kawashima, N. Trivedi
- Physics
- 19 February 2009

A strong-coupling expansion for the Green's functions, self-energies, and correlation functions of the Bose-Hubbard model is developed. We illustrate the general formalism, which includes all… Expand

Phase Transition in Potts Model with Invisible States

- R. Tamura, Shu Tanaka, N. Kawashima
- Physics
- 10 May 2010

We study phase transition in the ferromagnetic Potts model with invisible states that are added as redundant states by mean-field calculation and Monte Carlo simulation. Invisible states affect the… Expand

Phase Transition of Generalized Ferromagnetic Potts Model- Effect of Invisible States -

- Shu Tanaka, R. Tamura, N. Kawashima
- Physics
- 27 February 2011

We investigate the nature of the phase transition of the ferromagnetic Potts model with invisible states. The ferromagnetic Potts model with invisible states can be regarded as a straightforward… Expand

Dimensional reduction at a quantum critical point

- S. Sebastian, N. Harrison, +5 authors I. Fisher
- Physics, Medicine
- Nature
- 1 June 2006

Competition between electronic ground states near a quantum critical point (QCP)—the location of a zero-temperature phase transition driven solely by quantum-mechanical fluctuations—is expected to… Expand

Magnetic-field-induced condensation of triplons in Han Purple pigment BaCuSi2O6.

- M. Jaime, V. Correa, +9 authors K. Uchinokura
- Physics, Medicine
- Physical review letters
- 14 April 2004

Besides being an ancient pigment, BaCuSi2O6 is a quasi-2D magnetic insulator with a gapped spin dimer ground state. The application of strong magnetic fields closes this gap, creating a gas of… Expand

Recent Developments of World-Line Monte Carlo Methods

- N. Kawashima, K. Harada
- Physics
- 29 December 2003

World-line quantum Monte Carlo methods are reviewed with an emphasis on breakthroughs made in recent years. In particular, three algorithms – the loop algorithm, the worm algorithm, and the… Expand

Application of a continuous time cluster algorithm to the two-dimensional random quantum Ising ferromagnet

- H. Rieger, N. Kawashima
- Physics, Mathematics
- 10 February 1998

Abstract:A cluster algorithm formulated in continuous (imaginary) time is presented for Ising models in a transverse field. It works directly with an infinite number of time-slices in the imaginary… Expand
