This is a review of recent developments in Monte Carlo methods in the field of ultracold
gases. For bosonic atoms in an optical lattice we discuss path-integral Monte Carlo …

Charge transport in crystalline organic semiconductors is intrinsically limited by the
presence of large thermal molecular motions, which are a direct consequence of the weak …

Quantum systems are notoriously difficult to simulate with classical means. Recently, the
idea of using another quantum system—which is experimentally more controllable—as a …

Electron-lattice interactions play a prominent role in quantum materials, making a deeper
understanding of direct routes to phonon-mediated high-transition-temperature (T c) …

We present a new variational method for investigating the ground state and out of
equilibrium dynamics of quantum many-body bosonic and fermionic systems. Our approach …

Antiferromagnetism (AFM) such as Néel ordering is often closely related to Coulomb
interactions such as Hubbard repulsion in two-dimensional (2D) systems. Whether Néel …

Over the past several years, a new generation of quantum simulations has greatly expanded
our understanding of charge density wave phase transitions in Hamiltonians with coupling …

It is widely accepted that phonon-mediated high-temperature superconductivity is
impossible at ambient pressure, because of the very large effective masses of polarons or …

We present a machine-learning method for predicting sharp transitions in a Hamiltonian
phase diagram by extrapolating the properties of quantum systems. The method is based on …

Computing the charge mobility of molecular semiconductors requires a balanced set of
approximations covering both the electronic structure of the Hamiltonian parameters and the …
