Pressure induced phase transitions in PbTiO(3).
Recent theoretical simulations using density functional theory (DFT) and novel low temperature high energy x-ray diffraction experiments clearly show the existence of a high pressure morphotropic phase boundary (MPB) in pure PbTiO(3). The experiments show a richer phase diagram than the simulations, with multiple monoclinic phases (Pm and Cm) in the MPB region. In this paper we examine the MPB ...
متن کاملPressure-induced topological phase transitions in membranes.
Some highly unusual features of a lipid-water liquid crystal are revealed by high pressure x-ray diffraction, light scattering and dilatometric studies of the lamellar (bilayer Lα) to nonlamellar inverse hexagonal (HII) phase transition. (i) The size of the unit cell of the HII phase increases with increasing pressure. (ii) The transition volume, ∆Vbh, decreases and appears to vanish as the pre...
متن کاملPressure- and field-induced magnetic quantum phase transitions in TlCuCl3
Abstract TlCuCl3 is a quantum spin liquid of S = 1/2 Cu2+ dimers. Interdimer superexchange interactions give a three-dimensional magnon dispersion and a spin gap significantly smaller than the dimer coupling, which is closed by an applied hydrostatic pressure of approximately 2.5 kbar or by a magnetic field of 5.6 T, offering a unique opportunity to explore both the pressureand fieldinduced qua...
متن کاملAb-initio studies of pressure induced phase transitions in BaO
We use ab-initio Quantum Mechanics to study the zero temperature phase diagram of BaO. We calculate zero temperature Equations of State of different crystalline phases [B1 (NaCl), B8(NiAs), B2(CsCl), and distorted B2] using Density Functional Theory (DFT) with the generalized gradient approximation (GGA). We find the B1 structure to be the thermodynamically stable one at zero pressure; followed...
