Hamming Distance and the onset of quantum criticality
Tian-Cheng Yi, Richard T. Scalettar, Rubem Mondaini
Simulating models for quantum correlated matter unveils the inherent limitations of deterministic classical computations. In particular, in the case of quantum Monte Carlo methods,…
-Phase shift across stripes in a charge density wave system
Tao Ying, Richard Scalettar, Rubem Mondaini
Many strongly correlated materials are characterized by deeply intertwined charge and spin order. Besides their high superconducting transition temperatures, one of the central fea…
Charge Singlets and Orbital-Selective Charge Density Wave Transitions
Yuxi Zhang, Chunhan Feng, Rubem Mondaini +2
The possibility of "orbitally selective Mott transitions" within a multiband Hubbard model, in which one orbital with large on-site electron-electron repulsion is insulating…
Phase Diagram of the Su-Schrieffer-Heeger-Hubbard model on a square lattice
Chunhan Feng, Bo Xing, Dario Poletti +2
The Hubbard and Su-Schrieffer-Heeger Hamiltonians (SSH) are iconic models for understanding the qualitative effects of electron-electron and electron-phonon interactions respective…
Quantum Critical Points and the Sign Problem
Rubem Mondaini, Sabyasachi Tarat, Richard T. Scalettar
The "sign problem" (SP) is the fundamental limitation to simulations of strongly correlated materials in condensed matter physics, solving quantum chromodynamics at finite baryon d…
Deconvolving the components of the sign problem
S. Tarat, Bo Xiao, R. Mondaini +1
Auxiliary field Quantum Monte Carlo simulations of interacting fermions require sampling over a Hubbard-Stratonovich field introduced to decouple the interactions. The weight f…
