Number of relevant directions in Principal Component Analysis and Wishart random matrices
Satya N. Majumdar, Pierpaolo Vivo
We compute analytically, for large , the probability that a Wishart random matrix has eigenvalues exceeding a threshold , including it…
Universal Order Statistics of Random Walks
Gregory Schehr, Satya N. Majumdar
We study analytically the order statistics of a time series generated by the successive positions of a symmetric random walk of n steps with step lengths of finite variance σ^2. We…
Wigner-Crystal Formulation of Strong-Coupling Theory for Counter-ions Near Planar Charged Interfaces
L. Šamaj, E. Trizac
We present a new analytical approach to the strong electrostatic coupling regime (SC), that can be achieved equivalently at low temperatures, high charges, low dielectric permittiv…
Dissipative homogeneous Maxwell mixtures: ordering transition in the tracer limit
V. Garzó, E. Trizac
The homogeneous Boltzmann equation for inelastic Maxwell mixtures is considered to study the dynamics of tracer particles or impurities (solvent) immersed in a uniform granular gas…
Bose-Einstein Condensation of a Gaussian Random Field in the Thermodynamic Limit
Philippe Mounaix, Satya N. Majumdar, Abhimanyu Banerjee
We derive the criterion for the Bose-Einstein condensation (BEC) of a Gaussian field (real or complex) in the thermodynamic limit. The field is characterized by its covariance…
Irreversibilities and efficiency at maximum power of heat engines: illustrative case of a thermoelectric generator
Y. Apertet, H. Ouerdane, C. Goupil +1
Thermoelectric generators are particularly suitable to investigate the irreversible processes which govern the coupled transport of matter and heat in solid-state systems. We study…
Lévy flights on the half line
Reinaldo Garcia-Garcia, Alberto Rosso, Gregory Schehr
We study the probability distribution function (pdf) of the position of a Lévy flight of index 0<α<2 in presence of an absorbing wall at the origin. The solution of the associated…
Field Theory of Fluctuations in Glasses
Silvio Franz, Giorgio Parisi, Federico Ricci-Tersenghi +1
We develop a field-theoretical description of dynamical heterogeneities and fluctuations in supercooled liquids close to the (avoided) MCT singularity. Using quasi-equilibrium argu…
One-dimensional Particle Processes with Acceleration/Braking Asymmetry
Cyril Furtlehner, Jean-Marc Lasgouttes, Maxim Samsonov
The slow-to-start mechanism is known to play an important role in the particular shape of the Fundamental diagram of traffic and to be associated to hysteresis effects of traffic f…
Statistical physics-based reconstruction in compressed sensing
Florent Krzakala, Marc Mézard, François Sausset +2
Compressed sensing is triggering a major evolution in signal acquisition. It consists in sampling a sparse signal at low rate and later using computational power for its exact reco…
The non-perturbative renormalization group in the ordered phase
Jean-Michel Caillol
We study some analytical properties of the solutions of the non perturbative renormalization group flow equations for a scalar field theory with symmetry in the ordered phase…
Asymptotic analysis of the stochastic block model for modular networks and its algorithmic applications
Aurelien Decelle, Florent Krzakala, Cristopher Moore +1
In this paper we extend our previous work on the stochastic block model, a commonly used generative model for social and biological networks, and the problem of inferring functiona…
The convex hull for a random acceleration process in two dimensions
Alexis Reymbaut, Satya N. Majumdar, Alberto Rosso
We compute exactly the mean perimeter <L(T)> and the mean area <A(T)> of the convex hull of a random acceleration process of duration T in two dimensions. We use an exact mapping t…
Maximum relative height of elastic interfaces in random media
Joachim Rambeau, Sebastian Bustingorry, Alejandro B. Kolton +1
The distribution of the maximal relative height (MRH) of self-affine one-dimensional elastic interfaces in a random potential is studied. We analyze the ground state configuration…
Intersection of two TASEP traffic lanes with frozen shuffle update
C. Appert-Rolland, J. Cividini, H. J. Hilhorst
Motivated by interest in pedestrian traffic we study two lanes (one-dimensional lattices) of length that intersect at a single site. Each lane is modeled by a TASEP (Totally As…
Diffusion with Optimal Resetting
Martin R. Evans, Satya N. Majumdar
We consider the mean time to absorption by an absorbing target of a diffusive particle with the addition of a process whereby the particle is reset to its initial position with rat…
Frozen shuffle update for an asymmetric exclusion process with open boundary conditions
C. Appert-Rolland, J. Cividini, H. J. Hilhorst
We introduce a new update algorithm for exclusion processes, more suitable for the modeling of pedestrian traffic. Pedestrians are modeled as hard-core particles hopping on a discr…
A two-dimensional one component plasma and a test charge : polarization effects and effective potential
G. Téllez, E. Trizac
We study the effective interactions between a test charge Q and a one-component plasma, i.e. a complex made up of mobile point particles with charge q, and a uniform oppositely cha…
Susceptibility divergence, phase transition and multistability of a highly turbulent closed flow
P. -P. Cortet, E. Herbert, A. Chiffaudel +3
Using time-series of stereoscopic particle image velocimetry data, we study the response of a turbulent von Kármán swirling flow to a continuous breaking of its forcing symmetry. E…
Link between New Versions of the Hierarchical Reference Theory of Liquids and of the Non Perturbative Renormalization Group in Statistical Field Theory
Jean-Michel Caillol
I propose a new version of the Hierarchical Reference Theory of liquids. Two formalisms, one in the grand canonical ensemble, the other in the framework of statistical field theory…
Universality versus material dependence of fluctuation forces between metallic wires
Ehsan Noruzifar, Thorsten Emig, Roya Zandi
We calculate the Casimir interaction between two parallel wires and between a wire and a metall plate. The dielectric properties of the objects are described by the plasma, Drude a…
First passages for a search by a swarm of independent random searchers
C. Mejia-Monasterio, G. Oshanin, G. Schehr
In this paper we study some aspects of search for an immobile target by a swarm of N non-communicating, randomly moving searchers (numbered by the index k, k = 1, 2,..., N), which…
Long-range steady state density profiles induced by localized drive
Tridib Sadhu, Satya N. Majumdar, David Mukamel
We show that the presence of a localized drive in an otherwise diffusive system results in steady-state density and current profiles that decay algebraically to their global averag…
Interaction regimes for oppositely charged plates with multivalent counterions
Fabien Paillusson, Emmanuel Trizac
Within a mean field treatment of the interaction between two oppositely charged plates in a salt free solution, the distance at which a transition from an attractive to a repulsive…
