Thermal phase transition for some spin-boson models
(2013-09-01)
In this work we study two different spin-boson models. Such models are generalizations of the Dicke model, it means they describe systems of N identical two-level atoms coupled to a single-mode quantized bosonic field, ...

Effect of nearest neighbor Pb-O divacancy pairs on the ferroelectric-relaxor transition in Pb(Sc1/2Nb1/2)O3
(American Physical Society, 2008-12)
Molecular dynamics simulations were performed on a frst-principles-based effective Hamiltonian for Pb(Sc1/2Nb1/2)O3 (PSN) with nearest neighbor Pb-O divacancy pairs. Simulations were performed for PSN with ideal chemical ...

Phase Transition Characteristics in A-Site La3+ Modified Bi-Layered Aurivillius-Type Structure SrBi2Nb2O9 Ferroelectric Ceramics
(Taylor & Francis Ltd, 2015-10-13)
The phase transition characteristics have been investigated in lanthanum modified bismuth layer structured SrBi2Nb2O9 (SBN) ferroelectric ceramics, obtained from the conventional sintering method. In particular, structural, ...
Why is the electrocaloric effect so small in ferroelectrics?
(2016-05-19)
Ferroelectrics are attractive candidate materials for environmentally friendly solid state refrigeration free of greenhouse gases. Their thermal response upon variations of external electric fields is largest in the vicinity ...
