Vavilov-Cherenkov radiation for parallel motion in three-dimensional topological insulators
O. J. Franca, Stefan Yoshi Buhmann
Our study delves into the modifications observed in Vavilov-Cherenkov radiation when its generating charged particle moves parallel to an interface formed by two generic magnetoele…

Quantized Embedding Approaches for Collective Strong Coupling -- Connecting ab initio and macroscopic QED to Simple Models in Polaritonics
Frieder Lindel, Dominik Lentrodt, Stefan Yoshi Buhmann +1
Collective light-matter interactions have been used to control chemistry and energy transfer, yet accessible approaches that combine ab initio methodology with large many-body quan…

Photonic Bose-Einstein condensation in the continuum limit
Andris Erglis, Milan RadonjiÄ, Stefan Yoshi Buhmann
We investigate the properties of the photon Bose-Einstein condensate in the limit of small mode spacing. Alongside the well-known threshold of the phase transition at large mode sp…
