Understanding repulsively mediated superconductivity of correlated electrons via massively parallel DMRG
Adrian Kantian, Michele Dolfi, Matthias Troyer +1
The so-called minimal models of unconventional superconductivity are lattice models of interacting electrons derived from materials in which electron pairing arises from purely rep…
Pair Correlations in Doped Hubbard Ladders
Michele Dolfi, Bela Bauer, Sebastian Keller +1
Hubbard ladders are an important stepping stone to the physics of the two-dimensional Hubbard model. While many of their properties are accessible to numerical and analytical techn…
Matrix Product State applications for the ALPS project
Michele Dolfi, Bela Bauer, Sebastian Keller +5
The density-matrix renormalization group method has become a standard computational approach to the low-energy physics as well as dynamics of low-dimensional quantum systems. In th…
Hybridization expansion Monte Carlo simulation of multi-orbital quantum impurity problems: matrix product formalism and improved Monte Carlo sampling
Hiroshi Shinaoka, Michele Dolfi, Matthias Troyer +1
We explore two complementary modifications of the hybridization-expansion continuous-time Monte Carlo method, aiming at large multi-orbital quantum impurity problems. One idea is t…
Chiral spin liquid and emergent anyons in a Kagome lattice Mott insulator
B. Bauer, L. Cincio, B. P. Keller +4
Topological phases in frustrated quantum spin systems have fascinated researchers for decades. One of the earliest proposals for such a phase was the chiral spin liquid put forward…
Gapped and gapless spin liquid phases on the Kagome lattice from chiral three-spin interactions
Bela Bauer, Brendan P. Keller, Michele Dolfi +2
We argue that a relatively simple model containing only SU(2)-invariant chiral three-spin interactions on a Kagome lattice of S=1/2 spins can give rise to both a gapped and a gaple…
