Variance reduction with probing and Multilevel Monte Carlo in Lattice QCD
Andreas Frommer, Jose Jimenez-Merchan, Bruno Lang +2
Trace estimation is central in many lattice QCD computations, but the accuracy of the standard, stochastic Hutchinson method improves only with the square root of the sample size,…
Probing and graph coloring techniques for trace estimation in Lattice QCD
Mario Papace, Andreas Frommer, Jose Jimenez-Merchan +3
The computation of , where is the Wilson-Dirac matrix of Lattice QCD, is a fundamental and computationally demanding task with applications to disconnected…
Modeling Minimum Cost Network Flows With Port-Hamiltonian Systems
Onur Tanil Doganay, Kathrin Klamroth, Bruno Lang +2
We give a short overview of advantages and drawbacks of the classical formulation of minimum cost network flow problems and solution techniques, to motivate a reformulation of clas…
A new perspective on dynamic network flow problems via port-Hamiltonian systems
Onur Tanil Doganay, Kathrin Klamroth, Bruno Lang +2
We suggest a global perspective on dynamic network flow problems that takes advantage of the similarities to port-Hamiltonian dynamics. Dynamic minimum cost flow problems are formu…
Quartic multifractality and finite-size corrections at the spin quantum Hall transition
Martin Puschmann, Daniel Hernangómez-Pérez, Bruno Lang +2
The spin quantum Hall (or class C) transition represents one of the few localization-delocalization transitions for which some of the critical exponents are known exactly. Not know…
Self-consistent-field ensembles of disordered Hamiltonians: Efficient solver and application to superconducting films
Matthias Stosiek, Bruno Lang, Ferdinand Evers
Our general interest is in self-consistent-field (scf) theories of disordered fermions. They generate physically relevant sub-ensembles ("scf-ensembles") within a given Altland-Zir…
