A quantum Monte Carlo study of the high-pressure phases of solid hydrogen
… wavefunction uses single-body solutions from a mean-field calculation coupled with standard pair potential terms to achieve the most accurate results to date. Equally accurate results were realized for calculations in the disparate insulating molecular and metallic atomic regime. We performed a …

Cyclic polymer liquid crystal structures.
… of the Metropolis Monte Carlo technique and a mean field calculation. Two models have been studied by the Monte Carlo technique in the NVT ensemble. In the first, each complete molecule was represented by a disc-like interactions potential and a tendency for the molecules to align in columns …

Non-equilibrium dynamics in three-dimensional magnetic spin models and molecular motor-inspired one-dimensional exclusion processes
… antiferromagnet in the presence of an external field. The phase diagram of this system exhibits two critical lines that meet at a bicritical point. We study the aging scaling dynamics for the model C critical line, probe the model F critical line by investigating the system size dependence of …

Complex phase behavior of exotic oxides: optical spectroscopy studies
… phase separation in this compound. The magnetic field dependence of Raman spectra also indicates that the low temperature ferromagnetic phase is inhomogeneous. We observed signatures of the long-range charge ordering and short-range orbital ordering, respectively, on the dielectric functions of …
