Photon orbital angular momentum in a plasma vortex
J. T. Mendonça, B. Thidé, J. E. S. Bergman +4
We study theoretically the exchange of angular momentum between a photon beam and a plasma vortex, and demonstrate the possible excitation of photon angular momentum states in a pl…
Detecting orbital angular momentum in radio signals
H. Then, B. Thidé, J. T. Mendonça +5
Electromagnetic waves with an azimuthal phase shift are known to have a well defined orbital angular momentum. Different methods that allow for the detection of the angular momentu…
Spectral resolution in hyperbolic orbifolds, quantum chaos, and cosmology
H. Then
We present a few subjects from physics that have one in common: the spectral resolution of the Laplacian.
Computing the optimal protocol for finite-time processes in stochastic thermodynamics
Holger Then, Andreas Engel
Asking for the optimal protocol of an external control parameter that minimizes the mean work required to drive a nano-scale system from one equilibrium state to another in finite…
CMB Alignment in Multi-Connected Universes
R. Aurich, S. Lustig, F. Steiner +1
The low multipoles of the cosmic microwave background (CMB) anisotropy possess some strange properties like the alignment of the quadrupole and the octopole, and the extreme planar…
