Phonon soft modes and para- to ferro-electric phase transitions
نویسندگان
چکیده
In this special issue of Physica A in memory Professor Dietrich Stauffer, I first recall my impression on him while being his postdoc for a year at HLRZ. the following scientific part, discuss theory soft phonons with quartic nonlinear interactions. This is applied to cubic crystal BaTiO$_3$ phase transition from para- ferroelectric phase.

Phase Transitions in Soft Topographic
We have developed an algorithm (STVQ) for the optimization of neighborhood preserving maps by applying deterministic anneal-ing to an energy function for topographic vector quantization. The com-binatorial optimization problem is solved by introducing temperature dependent fuzzy assignments of data points to cluster centers and applying an EM-type algorithm at each temperature while annealing. ...
متن کاملKinetics of the field induced commensurate to ferro-electric phase transition in thiourea
The paper examines the kinetics of the electric field induced, first-order transition from the commensurate to the ferro-electric phase in thiourea (SC(NH2)2) at 170 K. The satellite reflection from the modulated phase, locked in with a wave vector q = 1/9b∗ disappears when the phase transition is induced by a static electric field Ec along the a-axis. In order to study the kinetics of the phas...
متن کاملQuantum phase transitions in one-dimensional electron-phonon systems
Low dimensional strongly coupled electron-phonon systems like MX-chains, ferroelectric perovskites, conjugated polymers, or organic charge transfer salts exhibit a remarkable wide range of strengths of competing forces and, as a result, physical properties [1]. Most notably quasi one-dimensional (1D) materials are very susceptible to structural distortions driven by the electron-phonon (EP) int...
متن کاملQuantum Phase Transitions and Collective Modes in d-wave Superconductors
Fluctuations near second-order quantum phase transitions in d-wave superconductors can cause strong damping of fermionic excitations, as observed in photoemission experiments. The damping of the gapless nodal quasiparticles can arise naturally in the quantum-critical region of a transition with an additional spin-singlet, zero momentum order parameter; we argue that the transition to a dx2−y2 +...
