TL;DR: In this paper, the total many-body correlations present in finite temperature classical spin systems were studied using the concept of mutual information, and the Shannon mutual information and the Renyi mutual information in both Ising and Potts models in two dimensions were calculated numerically by combining matrix product state algorithms and Monte Carlo sampling techniques.

TL;DR: In this paper, the ground state phase diagram of the one-dimensional Bose-Fermi Hubbard model is studied in the canonical ensemble using a quantum Monte Carlo method, focusing on the case where both species have half filling in order to maximize the pairing correlations between the bosons and the fermions.

TL;DR: In this paper, the authors numerically diagonalize a comprehensive effective Hamiltonian describing the fractional quantum Hall effect of electrons under realistic conditions in GaAs semiconductors, and find the ground state in both the torus and spherical geometries as a function of the quantum well and sub-band mixing.

TL;DR: The one-dimensional Kondo-lattice model is investigated using quantum Monte Carlo and transfer-matrix techniques and shows a Ruderman-Kittel-Kasuya-Yosida-like behavior in the weak-coupling region.

TL;DR: A persistent storage mechanism is proposed that manages input, intermediate, and output data files, strengthening the links between provenance and data and provides better support for reproducibility.
