PT-symmetric spectral singularity and negative frequency resonance
Sarang Pendharker, Yu Guo, Farhad Khosravi +1
Vacuum consists of a bath of balanced and symmetric positive and negative frequency fluctuations. Media in relative motion or accelerated observers can break this symmetry and pref…
Universal Zero Conductivity Condition for Optical Absorption
Yu Guo, Sarang Pendharker, Zubin Jacob
Harnessing information and energy from light within a nanoscale mode volume is a fundamental challenge for nanophotonic applications ranging from solar photovoltaics to single phot…
Thermal excitation of plasmons for near-field thermophotovoltaics
Yu Guo, Sean Molesky, Huan Hu +2
The traditional approaches of exciting plasmons consist of using electrons (eg: electron energy loss spectroscopy) or light (Kretchman and Otto geometry) while more recently plasmo…
Giant non-equilibrium vacuum friction: Role of singular evanescent wave resonances in moving media
Yu Guo, Zubin Jacob
We recently reported on the existence of a singular resonance in moving media which arises due to perfect amplitude and phase balance of evanescent waves. We show here that the non…
Fluctuational electrodynamics of hyperbolic metamaterials
Yu Guo, Zubin Jacob
We give a detailed account of equilibrium and non-equilibrium fluctuational electrodynamics of hyperbolic metamaterials. We show the unifying aspects of two different approaches; o…
Singular evanescent wave resonances
Yu Guo, Zubin Jacob
Resonators fold the path of light by reflections leading to a phase balance and thus constructive addition of propagating waves. However, amplitude decrease of these waves due to i…
