Probability density of fractional Brownian motion and the fractional Langevin equation with absorbing walls
Thomas Vojta, Alex Warhover
Fractional Brownian motion and the fractional Langevin equation are models of anomalous diffusion processes characterized by long-range power-law correlations in time. We employ la…
Phase boundary near a magnetic percolation transition
Gaurav Khairnar, Cameron Lerch, Thomas Vojta
Motivated by recent experimental observations [Phys. Rev. 96, 020407 (2017)] on hexagonal ferrites, we revisit the phase diagrams of diluted magnets close to the lattice percolatio…
Reflected fractional Brownian motion in one and higher dimensions
Thomas Vojta, Samuel Halladay, Sarah Skinner +3
Fractional Brownian motion (FBM), a non-Markovian self-similar Gaussian stochastic process with long-ranged correlations, represents a widely applied, paradigmatic mathematical mod…
Edge state critical behavior of the integer quantum Hall transition
Martin Puschmann, Philipp Cain, Michael Schreiber +1
The integer quantum Hall effect features a paradigmatic quantum phase transition. Despite decades of work, experimental, numerical, and analytical studies have yet to agree on a un…
