    Back-contact architectures for perovskite solar cells eliminate parasitic-absorption losses caused by the electrode and charge collection layers but increase surface reflection due to the high refractive index mismatch ...
  • FINITE THERMAL PARTICLE CREATION OF CASIMIR LIGHT 
    Good, Michael R. R.; Linder, Eric V.; Wilczek, Frank (Modern Physics Letters A, 2019)
    A new solution for an analytic spectrum of particle creation by an accelerating mir ror (dynamical Casimir effect) is given. It is the first model to simultaneously radiate thermally and emit a finite number of particles.

    Kwidzinski, Nick; Malafarina, Daniele; Ostrowski, Jan J.; Piechocki, Włodzimierz; Schmitz, Tim (arxiv, 2020-04)
    We consider the gravitational collapse of a self-gravitating spherical dust cloud in the Hamiltonian formalism. We address both homogeneous and inhomogeneous cases. Our novel derivation of the Hamiltonian of the system ...
  • LIGHT TRAPPING BY ARBITRARILY THIN CAVITIES 
    Zhumabek, Tilek; Valagiannopoulos, Constantinos (PHYSICAL REVIEW RESEARCH, 2020)
    Simple plasmonic multilayers are found to perfectly trap electromagnetic waves around specific incidence directions, regardless of the sample thickness. Such a counterintuitive feature is acquired via increasing un boundedly ...
