TL;DR: In this paper, a stable ordered CuPt-structure at x = 0.5Sb0.5 with alternating (111)-layers of As and Sb was considered, and it was shown that wires made of certain ordered alloys have spin splittings up to 20 times larger than those reached in pristine InSb wires.

TL;DR: In this paper, the authors theoretically analyze these structures and develop a procedure to accurately test proposed quantum Hall wavefunctions and find that tilted wells favor partial subband polarization to yield Abelian even-denominator states.

TL;DR: In this article, the authors present a generic approach to compute the fidelity susceptibility of correlated fermions, bosons, and quantum spin systems in a broad range of quantum Monte Carlo methods.

TL;DR: In this article, the authors present a numerical study of the Hubbard model on simply stacked honeycomb and square lattices, motivated by a recent experimental realization of such models with ultracold atoms in optical lattices.

TL;DR: In this paper, the authors studied the thermodynamic properties of the 3D Hubbard model for temperatures down to the Néel temperature by using cluster dynamical mean-field theory, and calculated the energy, entropy, density, double occupancy, and nearest-neighbor spin correlations as a function of chemical potential, temperature, and repulsion strength.
