Q-deformed fermionic Lipkin model at finite temperature
(1997-08-15)
The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in ...
Phase conversion in a weakly first-order quark-hadron transition

Maximally localized Wannier functions for describing a topological phase transition in stanene
(American Physical Society, 2021-01)
Starting from first-principles calculations on pristine stanene and using maximally localized Wannier functions (MLWFs), we analyze the different phases of the system when it is driven to a topological phase transition. ...
Field-induced length changes in the spin-liquid candidate κ-(BEDT-TTF) 2Cu 2(CN) 3
(2012-05-01)
Measurements of the coefficient of thermal expansion on the spin-liquid candidate κ-(BEDT-TTF) 2Cu 2(CN) 3 have revealed distinct and strongly anisotropic lattice effects around 6 K - a possible spin liquid instability. ...

Absence of relaxor-like ferroelectric phase transition in (Pb,Sr)TiO3 thin films
(Springer, 2005-02-01)
We have performed dielectric and micro-Raman spectroscopy measurements in the 298 - 673 K temperature range in polycrystalline Pb0.50Sr0.50TiO3 thin films prepared by a soft chemical method. The phase transition have been ...
