Cluster-size dependence in cellular dynamical mean-field theory
Shiro Sakai, Giorgio Sangiovanni, Marcello Civelli +3
We examine the cluster-size dependence of the cellular dynamical mean-field theory (CDMFT) applied to the two-dimensional Hubbard model. Employing the continuous-time quantum Monte…
Transition probability functions for inelastic electron--electron scattering
Stefan Löffler, Peter Schattschneider
In this work, the transition matrix elements for inelastic electron--electron scattering are investigated. The angular part is given by spherical harmonics. For the weighted radial…
Signature of antiferromagnetic long-range order in the optical spectrum of strongly correlated electron systems
C. Taranto, G. Sangiovanni, K. Held +3
We show how the onset of a non-Slater antiferromagnetic ordering in a correlated material can be detected by optical spectroscopy. Using dynamical mean-field theory we identify two…
Strong magnetic coupling of an inhomogeneous NV ensemble to a cavity
K. Sandner, H. Ritsch, R. Amsüss +5
We study experimentally and theoretically a dense ensemble of negatively charged nitrogen-vacancy centers in diamond coupled to a high superconducting coplanar waveguide cavity…
k-Gap Interval Graphs
Fedor V. Fomin, Serge Gaspers, Petr Golovach +5
We initiate the study of a new parameterization of graph problems. In a multiple interval representation of a graph, each vertex is associated to at least one interval of the real…
Attosecond streaking of correlated two-electron transitions in helium
Renate Pazourek, Stefan Nagele, Johannes Feist +1
We present fully ab initio simulations of attosecond streaking for ionization of helium accompanied by shake-up of the second electron. This process represents a prototypical case…
