I am particularly interested in the analytical and numerical modelling of the statistical properties of complex matter ranging from biological systems to powders.
My current research interests are:
Statistical aspects in jammed granular matter
Evolution of the mean packing fraction during a tapping experiment described as a fix point on a jamming curve (Mol.Phys. 2013)
Defining entropy for granular materials: linking packing structures to minima of an energy landscape and their probability of occurrence to the size of their corresponding basins of attraction enables one to define a protocol-dependent granular entropy (PRL 2014)
Time evolution of an ensemble volume histogram of a granular system undergoing a vertical tapping protocol (PRL 2012)
Effective interactions mediated by ions in solutions
Matching between a
Poisson-Boltzmann toy model and a Monte Carlo description for a sphere or an indented cylinder in interaction with a cylinder (PCCP 2011)
Sketch of the crossover between a single particle description and an effective Poisson-Boltzmann description of a counterion density at a plate in the Strong Coupling regime (PRE 2011)
Coarse grain modeling of biomolecules
mediated repulsion observed for a minimalmodel of a protein-DNA system (PRL 2009)
Kornyshev-Leikin model of two “counterion-dressed” DNAs in presence of multivalent ions (SoftMatter 2012)
Dynamics of a protein next to a DNA segment
Effective free energy
landscape on which
evolves a DNA-binding protein. Sliding and jumping processes are recovered
Sketch of what is believed to be the general behavior of most DNA-binding proteins around DNA. The effective use of different modes of displacement is believed to enhance the search time for a specific target on DNA (Adv.Prot.Chem.Struc. 2013)
Thermodynamics of mixtures
Mapping of the problem of demixing two polydisperse systems onto that of resetting one bit of information with a certain probability of success (J. Stat. Mech. 2014)
Competition between curvature and line tension in the phase separation of a binary mixture on a triply periodic minimal surface (Phys. Rev. Lett. 2016).
2-dimensional Critical Casimir Effect between anistropic inclusions: the case of objects comprising multiple domains with opposite affinities with the surrounding critical mixture (Phys. Chem.Chem.Phys 2017).
