Classification and characterization of nonequilibrium Higgs modes in unconventional superconductors
L. Schwarz, B. Fauseweh, N. Tsuji +8
Recent findings of new Higgs modes in unconventional superconductors require a classification and characterization of the modes allowed by nontrivial gap symmetry. Here we develop…
Comparison of the Iterated Equation of Motion Approach and the Density Matrix Formalism for the Quantum Rabi Model
Mona H. Kalthoff, Frederik Keim, Holger Krull +1
The density matrix formalism and the equation of motion approach are two semi-analytical methods that can be used to compute the non-equilibrium dynamics of correlated systems. Whi…
Minimal model for the frustrated spin ladder system BiCuPO
Leanna Splinter, Nils A. Drescher, Holger Krull +1
To establish the microscopic model of the compound BiCuPO is a challenging task. Inelastic neutron scattering experiments showed that the dispersion of this material is non…
Enhanced Perturbative Continuous Unitary Transformations
H. Krull, N. A. Drescher, G. S. Uhrig
Unitary transformations are an essential tool for the theoretical understanding of many systems by mapping them to simpler effective models. A systematically controlled variant to…
