Weak Solutions of the Stochastic Landau-Lifshitz-Gilbert Equation
Z. Brzezniak, B. Goldys
The Landau-Lifshitz-Gilbert equation perturbed by a multiplicative space-dependent noise is considered for a ferromagnet filling a bounded three-dimensional domain. We show the exi…
Quantum Inequalities from Operator Product Expansions
Henning Bostelmann, Christopher J. Fewster
Quantum inequalities are lower bounds for local averages of quantum observables that have positive classical counterparts, such as the energy density or the Wick square. We establi…
Quantum error correction beyond qubits
Takao Aoki, Go Takahashi, Tadashi Kajiya +4
Quantum computation and communication rely on the ability to manipulate quantum states robustly and with high fidelity. Thus, some form of error correction is needed to protect fra…
The Duffin-Schaeffer Conjecture with extra divergence
Alan Haynes, Andrew Pollington, Sanju Velani
Given a nonnegative function , let denote the set of real numbers such that for infinitely many reduced rationals . A conseq…
Aspects of locally covariant quantum field theory
Ko Sanders
This thesis considers various aspects of locally covariant quantum field theory (LCQFT; see Brunetti et al., Commun.Math.Phys. 237 (2003), 31-68), a mathematical framework to descr…
Ultra-fast spin dynamics: the effect of colored noise
U. Atxitia, O. Chubykalo-Fesenko, R. W. Chantrell +2
Recent experimental results have pushed the limits of magnetization dynamics to pico- and femtosecond timescales. This ultra-fast spin dynamics occurs in extreme conditions of stro…
