Influence phase of a dS observer. Part II. Electromagnetism

Journal of High Energy Physics
We extend our proposal for static patch holography made in part I to the case of electromagnetism. Using the on-shell action on de Sitter Schwinger-Keldysh (dS-SK) geometry, we derive the influence phase of an observer in dS d+1 interacting with bulk ...

The Cerenkov effect revisited: from swimming ducks to zero modes in gravitational analogs

, 2012
We present an interdisciplinary review of the generalized Cerenkov emission of radiation from uniformly moving sources in the different contexts of classical electromagnetism, superfluid hydrodynamics, and classical hydrodynamics.

Room‐Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle–Liquid Crystal System

Advanced Materials, EarlyView.
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Explicit Actions for Electromagnetism with Two Gauge Fields with Only one Electric and one Magnetic Physical Fields

, 2006
We extend the work of Mello et al. based in Cabbibo and Ferrari concerning the description of electromagnetism with two gauge fields from a variational principle, i.e. an action. We provide a systematic independent derivation of the allowed actions which
