  • Generalization of the Dynamical Lack-of-Fit Reduction from GENERIC to GENERIC
    J. Stat. Phys. (IF 1.513) Pub Date : 2020-05-27
    Michal Pavelka, Václav Klika, Miroslav Grmela

    The lack-of-fit statistical reduction, developed and formulated first by Bruce Turkington, is a general method taking Liouville equation for probability density (detailed level) and transforming it to reduced dynamics of projected quantities (less detailed level). In this paper the method is generalized. The Hamiltonian Liouville equation is replaced by an arbitrary Hamiltonian evolution combined with

  • Quantum Optimal Transport is Cheaper
    J. Stat. Phys. (IF 1.513) Pub Date : 2020-05-26
    E. Caglioti, F. Golse, T. Paul

    We compare bipartite (Euclidean) matching problems in classical and quantum mechanics. The quantum case is treated in terms of a quantum version of the Wasserstein distance. We show that the optimal quantum cost can be cheaper than the classical one. We treat in detail the case of two particles: the equal mass case leads to equal quantum and classical costs. Moreover, we show examples with different

    Let \(Z^1\) and \(Z^2\) be partition functions in the random polymer model in the same environment but driven by different underlying random walks. We give a comparison in concave stochastic order between \(Z^1\) and \(Z^2\) if one of the random walks has “more randomness” than the other. We also treat some related models: The parabolic Anderson model with space–time Lévy noise; Brownian motion among

    We present the complete theory for the decay rates of non-equilibrium fluctuations in a ternary liquid mixture subjected to a stationary temperature gradient, when the quiescent non-convective state is stable. In the most general case, within Boussinesq approximation, four fluctuating modes exist. Depending on the parameter values, propagative modes may be present, and we discuss numerically some cases

  • Marked Gibbs Point Processes with Unbounded Interaction: An Existence Result

    We construct marked Gibbs point processes in \({\mathbb {R}}^d\) under quite general assumptions. Firstly, we allow for interaction functionals that may be unbounded and whose range is not assumed to be uniformly bounded. Indeed, our typical interaction admits an a.s. finite but random range. Secondly, the random marks—attached to the locations in \({\mathbb {R}}^d\)—belong to a general normed space

    We study a 1-dimensional chain of N weakly anharmonic classical oscillators coupled at its ends to heat baths at different temperatures. Each oscillator is subject to pinning potential and it also interacts with its nearest neighbors.

  • On statistical modeling of sequencing noise in high depth data to assess tumor evolution.
    J. Stat. Phys. Pub Date : 2018-07-24
    Raul Rabadan,Gyan Bhanot,Sonia Marsilio,Nicholas Chiorazzi,Laura Pasqualucci,Hossein Khiabanian

    One cause of cancer mortality is tumor evolution to therapy-resistant disease. First line therapy often targets the dominant clone, and drug resistance can emerge from preexisting clones that gain fitness through therapy-induced natural selection. Such mutations may be identified using targeted sequencing assays by analysis of noise in high-depth data. Here, we develop a comprehensive, unbiased model

  • The Influence of Higher-Order Epistasis on Biological Fitness Landscape Topography.
    J. Stat. Phys. Pub Date : 2018-06-16
    Daniel M Weinreich,Yinghong Lan,Jacob Jaffe,Robert B Heckendorn

    The effect of a mutation on the organism often depends on what other mutations are already present in its genome. Geneticists refer to such mutational interactions as epistasis. Pairwise epistatic effects have been recognized for over a century, and their evolutionary implications have received theoretical attention for nearly as long. However, pairwise epistatic interactions themselves can vary with

  • Free Fermions and the Classical Compact Groups.
    J. Stat. Phys. Pub Date : 2018-01-01
    Fabio Deelan Cunden,Francesco Mezzadri,Neil O'Connell

    There is a close connection between the ground state of non-interacting fermions in a box with classical (absorbing, reflecting, and periodic) boundary conditions and the eigenvalue statistics of the classical compact groups. The associated determinantal point processes can be extended in two natural directions: (i) we consider the full family of admissible quantum boundary conditions (i.e., self-adjoint

  • Cluster Tails for Critical Power-Law Inhomogeneous Random Graphs.
    J. Stat. Phys. Pub Date : 2018-01-01
    Remco van der Hofstad,Sandra Kliem,Johan S H van Leeuwaarden

    Recently, the scaling limit of cluster sizes for critical inhomogeneous random graphs of rank-1 type having finite variance but infinite third moment degrees was obtained in Bhamidi et al. (Ann Probab 40:2299-2361, 2012). It was proved that when the degrees obey a power law with exponent τ ∈ ( 3 , 4 ) , the sequence of clusters ordered in decreasing size and multiplied through by n - ( τ - 2 ) / (

  • Canonical Structure and Orthogonality of Forces and Currents in Irreversible Markov Chains.
    J. Stat. Phys. Pub Date : 2018-01-01
    Marcus Kaiser,Robert L Jack,Johannes Zimmer

    We discuss a canonical structure that provides a unifying description of dynamical large deviations for irreversible finite state Markov chains (continuous time), Onsager theory, and Macroscopic Fluctuation Theory (MFT). For Markov chains, this theory involves a non-linear relation between probability currents and their conjugate forces. Within this framework, we show how the forces can be split into

  • A Re-entrant Phase Transition in the Survival of Secondary Infections on Networks.
    J. Stat. Phys. Pub Date : 2018-01-01
    Sam Moore,Peter Mörters,Tim Rogers

    We study the dynamics of secondary infections on networks, in which only the individuals currently carrying a certain primary infection are susceptible to the secondary infection. In the limit of large sparse networks, the model is mapped to a branching process spreading in a random time-sensitive environment, determined by the dynamics of the underlying primary infection. When both epidemics follow

  • Isolation and Connectivity in Random Geometric Graphs with Self-similar Intensity Measures.
    J. Stat. Phys. Pub Date : 2018-01-01
    Carl P Dettmann

    Random geometric graphs consist of randomly distributed nodes (points), with pairs of nodes within a given mutual distance linked. In the usual model the distribution of nodes is uniform on a square, and in the limit of infinitely many nodes and shrinking linking range, the number of isolated nodes is Poisson distributed, and the probability of no isolated nodes is equal to the probability the whole

    J. Stat. Phys. Pub Date : 2018-01-01
    Elliott H Lieb,Nicolas Rougerie,Jakob Yngvason

    We consider general N-particle wave functions that have the form of a product of the Laughlin state with filling factor 1 / ℓ and an analytic function of the N variables. This is the most general form of a wave function that can arise through a perturbation of the Laughlin state by external potentials or impurities, while staying in the lowest Landau level and maintaining the strong correlations of

  • Queues on a Dynamically Evolving Graph.
    J. Stat. Phys. Pub Date : 2018-01-01
    Michel Mandjes,Nicos J Starreveld,René Bekker

    This paper considers a population process on a dynamically evolving graph, which can be alternatively interpreted as a queueing network. The queues are of infinite-server type, entailing that at each node all customers present are served in parallel. The links that connect the queues have the special feature that they are unreliable, in the sense that their status alternates between 'up' and 'down'

  • Weighted Distances in Scale-Free Configuration Models.
    J. Stat. Phys. Pub Date : 2018-01-01
    Erwin Adriaans,Júlia Komjáthy

    In this paper we study first-passage percolation in the configuration model with empirical degree distribution that follows a power-law with exponent τ ∈ ( 2 , 3 ) . We assign independent and identically distributed (i.i.d.) weights to the edges of the graph. We investigate the weighted distance (the length of the shortest weighted path) between two uniformly chosen vertices, called typical distances

  • Triadic Closure in Configuration Models with Unbounded Degree Fluctuations.
    J. Stat. Phys. Pub Date : 2018-01-01
    Remco van der Hofstad,Johan S H van Leeuwaarden,Clara Stegehuis

    The configuration model generates random graphs with any given degree distribution, and thus serves as a null model for scale-free networks with power-law degrees and unbounded degree fluctuations. For this setting, we study the local clustering c(k), i.e., the probability that two neighbors of a degree-k node are neighbors themselves. We show that c(k) progressively falls off with k and the graph

    We study a recent model for edge exchangeable random graphs introduced by Crane and Dempsey; in particular we study asymptotic properties of the random simple graph obtained by merging multiple edges. We study a number of examples, and show that the model can produce dense, sparse and extremely sparse random graphs. One example yields a power-law degree distribution. We give some examples where the

  • PCA meets RG.
    J. Stat. Phys. Pub Date : 2017-05-01
    Serena Bradde,William Bialek

    A system with many degrees of freedom can be characterized by a covariance matrix; principal components analysis (PCA) focuses on the eigenvalues of this matrix, hoping to find a lower dimensional description. But when the spectrum is nearly continuous, any distinction between components that we keep and those that we ignore becomes arbitrary; it then is natural to ask what happens as we vary this
