Convex hull of a Brownian motion in confinement
M. Chupeau, O. Bénichou, S. N. Majumdar
We study the effect of confinement on the mean perimeter of the convex hull of a planar Brownian motion, defined as the minimum convex polygon enclosing the trajectory. We use a mi…
Finite temperature free fermions and the Kardar-Parisi-Zhang equation at finite time
David S. Dean, Pierre Le Doussal, Satya N. Majumdar +1
We consider the system of one-dimensional free fermions confined by a harmonic well at finite inverse temperature . The average density of fermi…
Fully developed isotropic turbulence: nonperturbative renormalization group formalism and fixed point solution
Léonie Canet, Bertrand Delamotte, Nicolás Wschebor
We investigate the regime of fully developed homogeneous and isotropic turbulence of the Navier-Stokes (NS) equation in the presence of a stochastic forcing, using the nonperturbat…
The contact theorem for charged fluids: from planar to curved geometries
Juan Pablo Mallarino, Gabriel Tellez, Emmanuel Trizac
When a Coulombic fluid is confined between two parallel charged plates, an exact relation links the difference of ionic densities at contact with the plates, to the surface charges…
Effect of Curvature and Confinement on the Casimir-Polder Interaction
Pablo Rodriguez-Lopez, Thorsten Emig, Ehsan Noruzifar +1
Modifications of Casimir-Polder interactions due to confinement inside a cylindrical cavity and due to curvature in- and outside the cavity are studied. We consider a perfectly con…
Ensemble inequivalence in a mean-field XY model with ferromagnetic and nematic couplings
Arkady Pikovsky, Shamik Gupta, Tarcisio N. Teles +4
We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spins with ferromagnetic and nematic coupling. We demonstrate the inequival…
