Quantum field theory in curved spacetimes (QFT in CS) has not only predicted
exciting physical phenomena, such as black hole radiation, the Unruh effect and
cosmological particle creation, but also lies at the intersection of many
mathematical subjects, and can arguably be viewed as a branch of mathematics
in its own right. In this talk, we shall give an inviting brief overview of QFT in CS.

Durante más de 50 años los cálculos perturbativos en Física de Altas Energías
se han realizado “a la Feynman”. Debido a la enorme cantidad de datos que se
obtienen en el LHC, es necesario contar con predicciones teóricas cada vez más
precisas. En los últimos años se ha avanzado con técnicas poderosas para
realizar cálculos de amplitudes de dispersión de manera eficiente, dando

A niveles de energías distintivas de una escala de compactificación hipotética,
las teorías de campo en dimensiones extras son descritas, en forma efectiva y
desde una perspectiva cuadridimensional, mediante teorías de Kaluza-Klein. Las
“simetrías escondidas”, por ejemplo presentes en el mecanismo de EnglertHiggs,
son esenciales para definir, entender e interpretar a las teorías de

Any acceptable version of a quantum theory of gravity must include, in the
appropriate limit, the recovery of the classical spacetime. Moreover, the
spacetime notion itself should be intrinsically tied to the behavior of the matter
that probes it. We consider some of difficulties that would be confronted in
attempting this enterprise. The problems we uncover seem to go beyond the
technical le

We take as a starting point an expression for the quantum geometric tensor
recently derived in the context of the gauge/gravity duality. We proceed to
generalize this formalism in such a way that it is possible to compute the
geometrical phases of quantum systems. Our scheme provides a conceptually
complete description and introduces a different point of view with respect to
earlier works. Us

The notorious problems in the description of high spins are traced back to the
inadequate (i) choice of the Lorentz algebra representation space used to embed
the high spin of interest, (ii) identification of the latter. A new approach based on
Lorentz and Poincaré invariant projectors is shown to help avoiding several of
the inconsistencies in high spin description.

We study the quantum cosmology of a quadratic f(𝑅) theory with a FRW metric,
via one of its equivalent Horndeski type actions, where the dynamic of the scalar
field is induced. The classical equations of motion and the Wheeler-DeWitt
equation, in their exact versions, are solved numerically. There is a free
parameter in the action from which two cases follow: inflation + exit and inflation

Se da una introducción a la Relatividad General pseudo-compleja. Se presentan
intentos anteriores para extender algebraicamente la teoría de Relatividad
General y se da la razón por qué solo la extensión a coordenadas pseudocomplejas
hace sentido. Se presentan las ecuaciones de Einstein modificadas y
su interpretación. Posteriormente, se reduce la teoría a una versión simplificada
y s
