Negative sign problem in continuous-time quantum Monte Carlo: optimal choice of single-particle basis for impurity problems
Hiroshi Shinaoka, Yusuke Nomura, Silke Biermann +2
The negative sign problem in quantum Monte Carlo (QMC) simulations of cluster impurity problems is the major bottleneck in cluster dynamical mean field calculations. In this paper…
Fate of the Kondo Effect and Impurity Quantum Phase Transitions Through the Lens of Fidelity Susceptibility
Lei Wang, Hiroshi Shinaoka, Matthias Troyer
The Kondo effect is an ubiquitous phenomenon appearing at low temperature in quantum confined systems coupled to a continuous bath. Efforts in understanding and controlling it have…
Analysis of Charge-spin-orbital Fluctuations by Ab Initio Calculation and Random Phase Approximation: Application to Non-coplanar Antiferromagnet Cd2Os2O7
Amane Uehara, Hiroshi Shinaoka, Yukitoshi Motome
We present a systematic analysis on the basis of ab initio calculations and many-body perturbation theory for clarifying the dominant fluctuation in complex charge-spin-orbital cou…
Charge-spin-orbital Fluctuations in Mixed Valence Spinels: Comparative Study of AlV2O4 and LiV2O4
Amane Uehara, Hiroshi Shinaoka, Yukitoshi Motome
Mixed valence spinels provide a fertile playground for the interplay between charge, spin, and orbital degrees of freedom in strongly correlated electrons on a geometrically frustr…
Phase diagram of pyrochlore iridates: all-in-all-out magnetic ordering and non-Fermi liquid properties
Hiroshi Shinaoka, Shintaro Hoshino, Matthias Troyer +1
We study the prototype 5d pyrochlore iridate Y2Ir2O7 from first principles using the local density approximation and dynamical mean-field theory (LDA+DMFT). We map out the phase di…
