Boundary crossing in stochastic inflation

School
ASTRONOMY

After a brief introduction of stochastic inflation, I explain the concept of boundary crossing and some tools for its calculation. Then I will present some results including the critical dependence of boundary crossing probability on the number of fields.. ...

Polymer translocation through a nanopore

Abstract:

Translocation of polymers through nanopores is ubiquitous in both biology and
biotechnology. In vivo, cell metabolism is completely dependent on biopolymer's
translocation such as RNA and polypeptides. On the other hand, in biotechnology, the
process is applicable in different areas such as controlled drug delivery, gene
sequencing, polymer separation, and protein sensing. In this talk, after addressing the
importance of polymer physics and especially polymer translocation, we will discuss
examples of both in vivo a ...

On gravitational energy, null stress tensor and the first law of holographic complexity

School
PARTICLES AND ACCELERATORS

Abstract: In this talk, I will review the geometry of null hypersurfaces. By analyzing surface terms of Einstein gravity on such boundaries I propose a new method for computation of gravitational charges. After that, in the context of holographic complexity, I will examine the variation of holographic complexity by studying different perturbations around various spacetime backgrounds. A general expression for the variation of the holographic complexity on arbitrary backgrounds will be presented by an explicit covariant computation.

Divergent Series, Asymptotic Expansions, Summability

School
MATHEMATICS

In this talk I will make a survey, with historical motivations, about the applications of divergent series in order to treat different problems related with differential equations. We will introduce the theory of summability, developed by Malgrange and Ramis among others, and present some recent progresses in this field, related with the treatment of singularly perturbed differential equations. More precisely, the theory of monomial asymptotic expansions will be presented with some applications and possible future developments. ...
