K. Bulycheva 1, 2 A. Gorsky 2, 3 S. Nechaev 4, 5 Physical Review D, American Physical Society, 2015, 92, pp.105006 We consider the relation between three physical problems: 2D directed lattice random walks, ensembles of $T_{n,n+1}$ torus knots, and instanton ensembles in 5D SQED with one compact dimension in $\Omega$ background and with 5D […]

Gunnar Claussen 1 Alexander K. Hartmann 1 Satya N. Majumdar 2 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 91, pp.052104 We study the convex hull of the set of points visited by a two-dimensional random walker of T discrete time steps. Two natural observables that characterize the convex

M. Chupeau 1 O. Bénichou 1 S. N. Majumdar 2 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 91, pp.050104 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

Pierre Ronceray 1 Martin Lenz 1 Soft Matter, Royal Society of Chemistry, 2015, 11, pp.1597 In contrast with ordinary materials, living matter drives its own motion by generating active, out-of-equilibrium internal stresses. These stresses typically originate from localized active elements embedded in an elastic medium, such as molecular motors inside the cell or contractile cells

Xiangyu Cao 1 Alberto Rosso 1 Raoul Santachiara 1 EPL, European Physical Society, 2015, 111, pp.16001 We study scaling properties of the honeycomb fully packed loop ensemble associated with a lozenge tiling model of rough surface, when the latter is driven out of equilibrium by Kardar-Parisi-Zhang (KPZ) type dynamics. We show numerically that conformal invariance

Shamik Gupta 1, 2, 3 Mustansir Barma 4 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2015, pp.P07018 We study the effect of quenched disorder on the zero-range process (ZRP), a system of interacting particles undergoing biased hopping on a one-dimensional periodic lattice, with the disorder entering through random capacities of sites. In the

Kabir Ramola 1 Kedar Damle 2 Deepak Dhar 2 Physical Review Letters, American Physical Society, 2015, 114, pp.190601 Particles with only hard-core interactions can exhibit interesting high-density phases. The cases of particles in the shape of $2\times2$ squares, and $2\times 1$ dimers on a square lattice have been studied for a long time. Here, we

Giuseppe Bimonte 1 Thorsten Emig 2 Mehran Kardar 3 Physical Review D, American Physical Society, 2015, 92, pp.025028 The Casimir–Polder interaction between an anisotropic particle and a surface is orientation dependent. We study novel orientational effects that arise due to curvature of the surface for distances much smaller than the radii of curvature by employing

Aurélien Grabsch 1 Christophe Texier 2 Europhysics letters – EPL, Association européenne de physique, 2015, 109, pp.50004 We consider the AC transport in a quantum RC circuit made of a coherent chaotic cavity with a top gate. Within a random matrix approach, we study the joint distribution for the mesoscopic capacitance $C_\mu=(1/C+1/C_q)^{-1}$ and the charge
