Soft mode theory of ferroelectric phase transitions in the low-temperature phase
Luigi Casella, Alessio Zaccone
Historically, the soft mode theory of ferroelectric phase transitions has been developed for the high-temperature (paraelectric) phase, where the phonon mode softens upon decreasin…

Physics of Phonon-Polaritons in Amorphous Materials
Luigi Casella, Matteo Baggioli, Tatsuya Mori +1
The nature of bosonic excitations in disordered materials has remained elusive due to the difficulties in defining key concepts such as quasi-particles in the presence of disorder.…
