Field-temperature phase diagram and entropy landscape of CeAuSb2

The Pressure-Temperature Phase Diagram of Metacetamol and Its Comparison to the Phase Diagram of Paracetamol.

Understanding the polymorphic behavior of active pharmaceutical ingredients is important for formulation purposes and regulatory reasons. Metacetamol is an isomer of paracetamol and it similarly exhibits polymorphism. In the present article, it has been found that one of the polymorphs of metacetamol is only stable under increased pressure, which has led to the conclusion that metacetamol like ...

Combinatorial entropy and phase diagram of partially ordered ice phases.

A close analytical estimate for the combinatorial entropy of partially ordered ice phases is presented. The expression obtained is very general, as it can be used for any ice phase obeying the Bernal-Fowler rules. The only input required is a number of crystallographic parameters, and the experimentally observed proton site occupancies. For fully disordered phases such as hexagonal ice, it reco...

Mean-field phase diagram of disordered bosons in a lattice at non-zero temperature

Abstract. Bosons in a periodic lattice with on-site disorder at low but non-zero temperature are considered within a mean-field theory. We show that, not only at vanishing but also at non-zero temperature, both the Mott-insulator and the Bose-glass phase are unambiguously distinguished by their density of states at small energies. We obtain the phase diagram of these phases as well as the super...

Thermodynamics and phase diagram of high temperature superconductors.

Thermodynamic quantities are derived for superconducting and pseudogap regimes by taking into account both amplitude and phase fluctuations of the pairing field. In the normal (pseudogap) state of the underdoped cuprates, two domains have to be distinguished: near the superconducting region, phase correlations are important up to temperature T(phi). Above T(phi), the pseudogap region is determi...
