Star-exponential for Fermi systems and the Feynman-Kac formula
J. Berra-Montiel, H. García-Compeán, A. Kafuri +1
Inspired by the formalism that relates the star-exponential with the quantum propagator for bosonic systems, in this work we introduce the analogous extension for the fermionic cas…

Path integrals and deformation quantization:the fermionic case
Anuar Kafuri
This thesis addresses a fundamental problem in deformation quantization: the difficulty of calculating the star-exponential, the symbol of the evolution operator, due to convergenc…

A supersymmetry journey from the Jaynes-Cummings to the anisotropic Rabi model
A. Kafuri, F. H. Maldonado-Villamizar, A. Moroz +1
We revisit the Jaynes-Cummings and anti-Jaynes-Cummings model through the lens of Lie theory, aiming to highlight the efficacy of an operator-based approach for diagonalization. We…
