Optical Control of the Thermal Conductivity in BaTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

Group Theory and Crystal Field Theory

1961
Publisher Summary The chapter describes crystal field theory that concerns with an attempt to calculate as much as possible about the behavior of solids on the basis of a known or assumed symmetry of the problem and with the simplifying assumption that the interaction between the ion or atom of interest and its nearest neighbors is electrostatic in ...

Polchinski's equation for group field theory

Fortschritte der Physik, 2014
AbstractWe derive an exact renormalization group equation in the context of (colored) group field theories. This equation describes the variation of the effective action as some of the modes of the fields are integrated out. From a combinatorial point of view, the effective action can be expressed using a boundary triangulation and the corresponding ...

Exotic Galileian group in field theory

Journal of Mathematical Sciences, 2006
The exotic Galileian group is realized as a symmetry group of a family of nonrelativistic field theories on the noncommutative plane. This was obtained in a unique way consistent with the Seiberg—Witten mapping. The symmetry group of the free model is analyzed and a characterization of the class of the self-interacting theories is given.
