This paper is the third part of an ongoing project, aimed at studying the continuity of weak solutions to multi-phase transition problems, modelled on (1.1). We refer to [9, 10] for a general overview of the problem and of the existing literature. Previously in [9] we dealt with β ...
Laser-driven shock compression experiments reveal the presence of a phase transition in MgSiO(3) over the pressure-temperature range 300-400 GPa and 10000-16000 K, with a positive Clapeyron slope and a volume change of 6.3 (±2.0) percent. The observations are most readily interpreted as an ...
As mentioned above,PCMscan absorb, store, and release large amounts of latentthermal energyduring phase transitions at their phase change points. Meanwhile, thephase change temperatureis a constant value during phase transition, which allows for the storage of energy and also gives a function stabili...
Structural, magnetic and superconducting phase transitions in CaFe2As2 under ambient and applied pressure At ambient pressure CaFe 2As 2 has been found to undergo a first order phase transition from a high temperature, tetragonal phase to a low-temperature orth... PC Canfield,SL Bud’Ko,N Ni,...

(one at a lower temperature). Temperature is not the equivalent of the energy of athermodynamic system; e.g., a burning match is at a much higher temperature than aniceberg, but thetotal heatenergy contained in an iceberg is much greater than the energy contained in a match. Temperature,...
Itetragonal and MnIIFeIIIcubic states, both stable at room temperature. The LT-to-HT phase transition can also be induced by laser irradiation at room temperature within the thermal hysteresis. As shown in Fig.1a, the characteristic colour change occurs at the laser spots, leading to a ...
Effect of uniaxial pressure on the ferroelectric phase transition in Pb5Ge3O11 The effect of uniaxial pressure (X) up to 1 kbar, applied along the three main directions, on the Curie temperature and the dielectric constant εc of a Pb... Koralewski,M.,Molak,... - 《Journal of Physics...
We report on a temperature-induced transition from a conventional semiconductor to a two-dimensional topological insulator investigated by means of magnetotransport experiments on HgTe/CdTe quantum well structures. At low temperatures, we are in the regime of the quantum spin Hall effect and observe ...
