Numerical evidence of quantum melting of spin ice: quantum-classical crossover
Yasuyuki Kato, Shigeki Onoda
Unbiased quantum Monte-Carlo simulations are performed on the nearest-neighbor spin- pyrochlore XXZ model with an antiferromagnetic longitudinal and a weak ferromagnet…
Efficient Langevin Simulation of Coupled Classical Fields and Fermions
Kipton Barros, Yasuyuki Kato
We introduce an efficient Langevin method to study bilinear Fermionic Hamiltonians interacting with classical fields. Our method is suitable for very large systems and offers high…
Multi-discontinuity algorithm for world-line Monte Carlo simulations
Yasuyuki Kato
We introduce a novel multi-discontinuity algorithm for efficient global update of world-line configurations in Monte Carlo simulations of interacting quantum systems. This new algo…
Finite-Size Scaling for Quantum Criticality above the Upper Critical Dimension: Superfluid-Mott-Insulator Transition in Three Dimensions
Yasuyuki Kato, Naoki Kawashima
Validity of modified finite-size scaling above the upper critical dimension is demonstrated for the quantum phase transition whose dynamical critical exponent is . We consider…
