First principles investigations of the electronic, magnetic and chemical bonding properties of CeTSn (T=Rh,Ru)
S. F. Matar, J. F. Riecken, B. Chevalier +2
The electronic structures of CeRhSn and CeRuSn are self-consistently calculated within density functional theory using the local spin density approximation for exchange and correla…
On the conundrum of deriving exact solutions from approximate master equations
Roland Doll, David Zueco, Martijn Wubs +2
We derive the exact time-evolution for a general quantum system under the influence of pure phase-noise and demonstrate that for a Gaussian initial state of the bath, the exact res…
Existence and symmetry of minimizers for nonconvex radially symmetric variational problems
Stefan Krömer
Nonconvex functionals with spherical symmetry are studied. Existence of one and radial symmetry of all global minimizers is shown with an approach based on convex relaxation.
Exact many-electron ground states on the diamond Hubbard chain
Zsolt Gulacsi, Arno Kampf, Dieter Vollhardt
Exact ground states of interacting electrons on the diamond Hubbard chain in a magnetic field are constructed which exhibit a wide range of properties such as flat-band ferromagnet…
Entanglement creation in circuit QED via Landau-Zener sweeps
Martijn Wubs, Sigmund Kohler, Peter Hanggi
A qubit may undergo Landau-Zener transitions due to its coupling to one or several quantum harmonic oscillators. We show that for a qubit coupled to one oscillator, Landau-Zener tr…
A new electromagnetic mode in graphene
S. A. Mikhailov, K. Ziegler
A new, weakly damped, {\em transverse} electromagnetic mode is predicted in graphene. The mode frequency lies in the window , where is the chemical potent…
