Split orthogonal group: A guiding principle for sign-problem-free fermionic simulations
Lei Wang, Ye-Hua Liu, Mauro Iazzi +2
We present a guiding principle for designing fermionic Hamiltonians and quantum Monte Carlo (QMC) methods that are free from the infamous sign problem by exploiting the Lie groups…
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…
Topological Origin of the Fermion Sign Problem
Mauro Iazzi, Alexey A. Soluyanov, Matthias Troyer
Monte Carlo simulations are a powerful tool for elucidating the properties of complex systems across many disciplines. Not requiring any a priori knowledge, they are particularly w…
Spontaneous Symmetry Breaking via Measurement: From Bose-Einstein Condensates to Josephson Effect
Takaaki Monnai, Mauro Iazzi, Kazuya Yuasa
Why does spontaneous symmetry breaking occur? Why is a state breaking symmetry realized? We explore an idea that measurement selects such a state even if a system is given in a sta…
Thermodynamics and magnetic properties of the anisotropic 3D Hubbard model
Jakub Imriška, Mauro Iazzi, Lei Wang +7
We study the 3D Hubbard model with anisotropic nearest neighbor tunneling amplitudes using the dynamical cluster approximation and compare the results with a quantum simulation exp…
