Quasi-adiabatic path integral approach for quantum systems under the influence of multiple non-commuting fluctuations
Timo Palm, Peter Nalbach
Quantum systems are typically subject to various environmental noise sources. Treating these environmental disturbances with a system-bath approach beyond weak coupling one must re…

Magnus expansion for a chirped quantum two-level system
Peter Nalbach, Vicente Leyton
We derive a Magnus expansion for a frequency chirped quantum two-level system. We obtain a time-independent effective Hamiltonian which generates a stroboscopic time evolution. At…

Nonuniversality and strongly interacting two-level systems in glasses at low temperatures
Moshe Schechter, Peter Nalbach, Alexander L. Burin
Recent experimental results showing untypical nonlinear absorption and marked deviations from well known universality in the low temperature acoustic and dielectric losses in amorp…
