Gutenberg-Richter Scaling - A New Paradigm

C. A. Serino, K. F. Tiampo, W. Klein

We introduce a new model for an earthquake fault system that is composed of non-interacting simple lattice models with different levels of damage denoted by . The undamaged latt…

Zero-Temperature Freezing in Three-Dimensional Kinetic Ising Model

J. Olejarz, P. L. Krapivsky, S. Redner

We investigate the long-time properties of the Ising-Glauber model on a periodic cubic lattice after a quench to zero temperature. In contrast to the conventional picture from phas…

First Passage in Infinite Paraboloidal Domains

P. L. Krapivsky, S. Redner

We study first-passage properties for a particle that diffuses either inside or outside of generalized paraboloids, defined by y=a(x_1^2+...+x_{d-1}^2)^{p/2} where p>1, with absorb…

A Light impurity in an Equilibrium Gas

L. D'Alessio, P. L. Krapivsky

We investigate the evolution of a light impurity particle in a Lorentz gas where the background atoms are in thermal equilibrium. As in the standard Lorentz gas, we assume that the…

Oscillating fidelity susceptibility near a quantum multicritical point

Victor Mukherjee, Anatoli Polkovnikov, Amit Dutta

We study scaling behavior of the geometric tensor and the fidelity susceptibility in the vicinity of a quantum multicritical point (MCP) using the…

Large decrease of fluctuations for supercooled water in hydrophobic nanoconfinement

Elena G. Strekalova, Marco G. Mazza, H. Eugene Stanley +1

We study by Monte Carlo simulations a coarse-grained model of a water layer confined in a fixed disordered matrix of hydrophobic nanoparticles at different particle concentrations…

First-Passage Exponents of Multiple Random Walks

E. Ben-Naim, P. L. Krapivsky

We investigate first-passage statistics of an ensemble of N noninteracting random walks on a line. Starting from a configuration in which all particles are located in the positive…

Statistical mechanics of transcription-factor binding site discovery using Hidden Markov Models

Pankaj Mehta, David Schwab, Anirvan M. Sengupta

Hidden Markov Models (HMMs) are a commonly used tool for inference of transcription factor (TF) binding sites from DNA sequence data. We exploit the mathematical equivalence betwee…

Nonequilibrium dynamics of closed interacting quantum systems

Anatoli Polkovnikov, Krishnendu Sengupta, Alessandro Silva +1

This colloquium gives an overview of recent theoretical and experimental progress in the area of nonequilibrium dynamics of isolated quantum systems. We particularly focus on quant…

Facilitated Asymmetric Exclusion

Alan Gabel, P. L. Krapivsky, S. Redner

We introduce a class of facilitated asymmetric exclusion processes in which particles are pushed by neighbors from behind. For the simplest version in which a particle can hop to i…

Exact results on the quench dynamics of the entanglement entropy in the toric code

Armin Rahmani, Claudio Chamon

We study quantum quenches in the two-dimensional Kitaev toric code model and compute exactly the time-dependent entanglement entropy of the non-equilibrium wave-function evolving f…

First-Passage Properties of Bursty Random Walks

D. Volovik, S. Redner

We investigate the first-passage properties of bursty random walks on a finite one-dimensional interval of length L, in which unit-length steps to the left occur with probability c…

Fluctuations in Polymer Translocation

Paul Krapivsky, Kirone Mallick

We investigate a model of chaperone-assisted polymer translocation through a nanopore in a membrane. Translocation is driven by irreversible random sequential absorption of chapero…

First Passage Properties of the Polya Urn Process

Tibor Antal, E. Ben-Naim, P. L. Krapivsky

We study first passage statistics of the Polya urn model. In this random process, the urn contains two types of balls. In each step, one ball is drawn randomly from the urn, and su…

Random Ancestor Trees

E. Ben-Naim, P. L. Krapivsky

We investigate a network growth model in which the genealogy controls the evolution. In this model, a new node selects a random target node and links either to this target node, or…

Maximum of N Independent Brownian Walkers till the First Exit From the Half Space

P. L. Krapivsky, Satya N. Majumdar, Alberto Rosso

We consider the one-dimensional target search process that involves an immobile target located at the origin and searchers performing independent Brownian motions starting at t…

Spanning trees for the geometry and dynamics of compact polymers

Armin Rahmani, Andrea Velenich, Claudio Chamon

Using a mapping of compact polymers on the Manhattan lattice to spanning trees, we calculate exactly the average number of bends at infinite temperature. We then find, in a high te…

Quantum mechanical and information theoretic view on classical glass transitions

Claudio Castelnovo, Claudio Chamon, David Sherrington

Using the mapping of the Fokker-Planck description of classical stochastic dynamics onto a quantum Hamiltonian, we argue that a dynamical glass transition in the former must have a…

Slow Cooling of an Ising Ferromagnet

P. L. Krapivsky

A ferromagnetic Ising chain which is endowed with a single-spin-flip Glauber dynamics is investigated. For an arbitrary annealing protocol, we derive an exact integral equation for…
