Numerical Estimation of Limiting Large-Deviation Rate Functions

Peter Werner, Alexander K. Hartmann

For statistics of rare events in systems obeying a large-deviation principle, the rate function is a key quantity. When numerically estimating the rate function one is always restr…

Numerical Aspects of Large Deviations

Alexander K. Hartmann

An introduction to numerical large-deviation sampling is provided. First, direct biasing with a known distribution is explained. As simple example, the Bernoulli experiment is used…

Non-universality for Crossword Puzzle Percolation

Alexander K. Hartmann

A percolation model inspired by crossword puzzle games is introduced. A game proceeds by solving words, which are segments of sites in a two-dimensional lattice. As test case, the…

Coexistence of asynchronous and clustered dynamics in noisy inhibitory neural networks

Yannick Feld, Alexander K. Hartmann, Alessandro Torcini

A regime of coexistence of asynchronous and clustered dynamics is analyzed for globally coupled homogeneous and heterogeneous inhibitory networks of quadratic integrate-and-fire (Q…

Work Distribution for Unzipping Processes

P. Werner, A. K. Hartmann, S. N. Majumdar

A simple zipper model is introduced, representing in a simplified way, e.g., the folded DNA double helix or hairpin structures in RNA. The double stranded hairpin is connected to a…

Large-deviation analysis of rare resonances for the Many-Body localization transition

Giulio Biroli, Alexander K. Hartmann, Marco Tarzia

A central theoretical issue at the core of the current research on many-body localization (MBL) consists in characterizing the statistics of rare long-range resonances in many-body…

Optimized Finite-Time Work Protocols for the Higgs RNA-Model

Peter Werner, Alexander K. Hartmann

The Higgs RNA-Model is studied in regard to finite-time driving protocols with minimal-work requirement. In this paper, RNA sequences which at low temperature exhibits hairpins are…

Ordering Behavior of the Two-Dimensional Ising Spin Glass with Long-Range Correlated Disorder

L. Münster, C. Norrenbrock, A. P. Young +1

The standard two-dimensional Ising spin glass does not exhibit an ordered phase at finite temperature. Here, we investigate whether long-range correlated bonds change this behavior…

Directed negative-weight percolation

Christoph Norrenbrock, Mitchell M. Mkrtchian, Alexander K. Hartmann

We consider a directed variant of the negative-weight percolation model in a two-dimensional, periodic, square lattice. The problem exhibits edge weights which are taken from a dis…
