A Minimal Supersymmetric Model of Particle Physics and the Early Universe

open access: yes, 2013
We consider a minimal supersymmetric extension of the Standard Model, with right-handed neutrinos and local B-L, the difference between baryon and lepton number, a symmetry which is spontaneously broken at the scale of grand unification. To a large extent, the parameters of the model are determined by gauge and Yukawa couplings of quarks and leptons ...

Elementary particles and the early Universe:A synergy of particle physics and cosmology in the birth and evolution of the Universe

open access: yes, 2022
The birth of the Universe, and its subsequent evolution, is an exciting blend of Cosmology, Particle Physics and Thermodynamics. This book, with its synoptic approach, provides an accessible introduction to these fascinating topics.

Quantum interference in gravitational particle production

open access: yesJournal of High Energy Physics, 2022
Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral density of the produced particles.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Bubble-wall velocity in local thermal equilibrium: hydrodynamical simulations vs analytical treatment

open access: yesJournal of High Energy Physics
We perform real-time hydrodynamical simulations of the growth of bubbles formed during cosmological first-order phase transitions under the assumption of local thermal equilibrium.

Inflection-point inflation and dark matter redux

open access: yesJournal of High Energy Physics, 2022
We investigate for viable models of inflation that can successfully produce dark matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic Microwave Background (CMB) and from some other observations.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Non-linearities in cosmological bubble wall dynamics

open access: yesJournal of High Energy Physics
A precise modelling of the dynamics of bubbles nucleated during first-order phase transitions in the early Universe is pivotal for a quantitative determination of various cosmic relics, including the stochastic background of gravitational waves.

On the physical basis of cosmic time [PDF]

open access: yes, 2008
In this manuscript we initiate a systematic examination of the physical basis for the time concept in cosmology. We discuss and defend the idea that the physical basis of the time concept is necessarily related to physical processes which could ...
