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…
Controllable chirality-induced geometrical Hall effect in a frustrated highly-correlated metal
B. G. Ueland, C. F. Miclea, Yasuyuki Kato +11
A current of electrons traversing a landscape of localized spins possessing non-coplanar magnetic order gains a geometrical (Berry) phase which can lead to a Hall voltage independe…
Structure of magnetic order in Pauli limited unconventional superconductors
Yasuyuki Kato, C. D. Batista, I. Vekhter
We analyse the magnetic structure of the antiferromagnetic order induced in Pauli limited d-wave superconductors by Zeeman coupling to magnetic field. We determine the phase diagra…
Magnetic and nematic orderings in spin-1 antiferromagnets with single-ion anisotropy
Keola Wierschem, Yasuyuki Kato, Yusuke Nishida +2
We study a spin-one Heisenberg model with exchange interaction, J, uniaxial single-ion exchange anisotropy, D, and Zeeman coupling to a magnetic field, B, parallel to the symmetry…
Efimov effect in quantum magnets
Yusuke Nishida, Yasuyuki Kato, Cristian D. Batista
Physics is said to be universal when it emerges regardless of the underlying microscopic details. A prominent example is the Efimov effect, which predicts the emergence of an infin…
Orbital disorder induced by charge fluctuations in vanadium spinels
Yasuyuki Kato, Gia-Wei Chern, K. A. Al-Hassanieh +2
Motivated by recent experiments on vanadium spinels, VO, that show an increasing degree of electronic delocalization for smaller cation sizes, we study the evolution of…
