Quantum Scattering in Schwarzschild Spacetime: Hawking Radiation and Black Hole Atmospheres
Victor H. Alencar, Gabriel Picanço, Carlos A. D. Zarro
In this paper, we investigate scattering of a scalar field near a Schwarzschild black hole through its -matrix. Within this framework, we obtain a novel derivation of Hawking ra…

Fixed points of semi-simple supersymmetric gauge theories
Andrew D. Bond, Daniel F. Litim, Gabriel Picanço
We study fixed points and phase diagrams of semi-simple supersymmetric gauge theories coupled to chiral superfields and a superpotential. Particular emphasis is put on new phenomen…

Symmetric Yang--Mills theory in FLRW universes
Mahir Ertürk, Gabriel Picanço
In this work, we set up the theoretical framework and indicate future applications of symmetric Yang--Mills fields to cosmology. We analyze the coset space dimensional reduction sc…
