Efficient Continuous-time Quantum Monte Carlo Method for the Ground State of Correlated Fermions
Lei Wang, Mauro Iazzi, Philippe Corboz +1
We present the ground state extension of the efficient quantum Monte Carlo algorithm for lattice fermions of arXiv:1411.0683. Based on continuous-time expansion of imaginary-time p…
Efficient continuous-time quantum Monte Carlo algorithm for fermionic lattice models
Mauro Iazzi, Matthias Troyer
Efficient continuous time quantum Monte Carlo (CT-QMC) algorithms that do not suffer from time discretization errors have become the state-of-the-art for most discrete quantum mode…
Probing the stability of the spin liquid phases in the Kitaev-Heisenberg model using tensor network algorithms
Juan Osorio Iregui, Philippe Corboz, Matthias Troyer
We study the extent of the spin liquid phases in the Kitaev-Heisenberg model using infinite Projected Entangled-Pair States tensor network ansatz wave functions directly in the the…
Renyi Entanglement Entropy of Interacting Fermions Calculated Using Continuous-Time Quantum Monte Carlo Method
Lei Wang, Matthias Troyer
We present a new algorithm for calculating the Renyi entanglement entropy of interacting fermions using the continuous-time quantum Monte Carlo method. The algorithm only samples i…
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…
Fermionic Quantum Critical Point of Spinless Fermions on a Honeycomb Lattice
Lei Wang, Philippe Corboz, Matthias Troyer
Spinless fermions on a honeycomb lattice provide a minimal realization of lattice Dirac fermions. Repulsive interactions between nearest neighbors drive a quantum phase transition…
