Commensurate lock-in and incommensurate supersolid phases of hardcore bosons on anisotropic triangular lattices
Sergei V. Isakov, Hong-Chi Chien, Jian-Jheng Wu +4
We investigate the interplay between commensurate lock-in and incommensurate supersolid phases of the hardcore bosons at half-filling with anisotropic nearest-neighbor hopping and…
Two-stage Kondo effect in side-coupled quantum dots: Renormalized perturbative scaling theory and Numerical Renormalization Group analysis
Chung-Hou Chung, Gergely Zarand, Peter Wölfle
We study numerically and analytically the dynamical (AC) conductance through a two-dot system, where only one of the dots is coupled to the leads but it is also side-coupled to the…
Quantum phase transitions in a resonant-level model with dissipation: Renormalization-group studies
Chung-Hou Chung, Matthew T. Glossop, Lars Fritz +3
We study a spinless level that hybridizes with a fermionic band and is also coupled via its charge to a dissipative bosonic bath. We consider the general case of a power-law hybrid…
