Relevance of long-range screening in Mott transition examined via a hydrogen lattice
Zi-Jian Lang, Sudeshna Sen, Pak Ki Henry Tsang +3
The Mott transition, a metal-insulator transition due to strong electronic interaction, is observed in many materials without an accompanying change of system symmetry. An importan…
Doping a Wigner-Mott insulator: Exotic charge orders in transition-metal dichalcogenide moiré heterobilayers
Yuting Tan, Pak Ki Henry Tsang, Vladimir Dobrosavljević +1
The moiré pattern induced by lattice mismatch in transition-metal dichalcogenide heterobilayers causes the formation of flat bands, where interactions dominate the kinetic energy.…
Disorder-dominated quantum criticality in moiré bilayers
Yuting Tan, Pak Ki Henry Tsang, V. Dobrosavljević
Moiré bilayer materials have recently attracted much attention following the discovery of various correlated insulating states at specific band fillings. Here we discuss the metal-…
Quantum-embedding description of the Anderson lattice model with the ghost Gutzwiller Approximation
Marius S. Frank, Tsung-Han Lee, Gargee Bhattacharyya +5
We present benchmark calculations of the Anderson lattice model based on the recently-developed "ghost Gutzwiller approximation". Our analysis shows that, in some parameters regime…
