    • Pressure dependence of ferroelectric quantum critical fluctuation 

      Coak, Matthew J.; Haines, Charles Robert Sebastian; Liu, Cheng; Guzmán Verri, Gian Giacomo; Saxena, Siddharth S. (2019-12-13)
      Phase transitions to a long-range-ordered state driven by a softened phonon mode are ubiquitous across condensed matter physics, but the evolution of such a mode as the system is tuned to or from the transition has never ...

    • Quantum Ferroelectric Instabilities in Superconducting SrTiO3 

      Arce Gamboa, José Rafael; Guzmán Verri, Gian Giacomo (2018)
      We examine the effects of strain and cation substitution on the superconducting phase of polar semiconductors near a ferroelectric quantum phase transition with a model that combines a strong coupling theory of ...
