Path integral of the relativistic point particle in Minkowski space

Publications / Por

B. Koch and E. Muñoz, “Path integral of the relativistic point particle in Minkowski space”, Physical Review D 103, 105025 (2021) In this article, we analyze the fundamental global and local symmetries involved in the action for the free relativistic point particle in Minkowski space. Moreover, we identify a hidden local symmetry, whose explicit consideration …

Chemical sensing with graphene: A quantum field theory perspective

Publications / Por

H. Falomir, M. Loewe and E. Muñoz, “Chemical sensing with graphene: A quantum field theory perspective”, Physical Review B 103, 235431 (2021) We studied theoretically the effect of a low concentration of adsorbed polar molecules on the optical conductivity of graphene, within the Kubo linear response approximation. Our analysis is based on a continuum model …
