High pressure layered structure of carbon disulfide
S. Shahab Naghavi, Yanier Crespo, Roman Martonak +1
Solid CS is superficially similar to CO, with the same molecular crystal structure at low pressures, which has suggested similar phases also at high pressures. W…
Collective spin 1 singlet phase in high pressure oxygen
Y. Crespo, M. Fabrizio, S. Scandolo +1
Oxygen, one of the most common and important elements in nature, has an exceedingly well explored phase diagram under pressure, up and beyond 100 GPa. At low temperatures, the low…
Competing Antiferromagnetic and Spin-Glass Phases in a Hollandite Structure
Y. Crespo, A. Andreanov, N. Seriani
We introduce a simple lattice model with Ising spins to explain recent experimental results on spin freezing in a hollandite-type structure. We argue that geometrical frustration o…
Calculating Thermodynamics Properties of Quantum Systems by a non-Markovian Monte Carlo Procedure
Yanier Crespo, Alessandro Laio, Giuseppe E. Santoro +1
We present a history-dependent Monte Carlo scheme for the efficient calculation of the free-energy of quantum systems, inspired by the Wang-Landau sampling and metadynamics method.…
