Winding vector: how to annihilate two Dirac points with the same charge
Gilles Montambaux, Lih-King Lim, Jean-Noël Fuchs +1
The merging or emergence of a pair of Dirac points may be classified according to whether the winding numbers which characterize them are opposite ( scenario) or identical ($++…
Elastic properties of solid material with various arrangements of spherical voids
Sascha Heitkam, Wiebke Drenckhan, Thomas Titscher +5
In this work the linear elastic properties of materials containing spherical voids are calculated and compared using finite element simulations. The focus is on homogeneous solid m…
From dia- to paramagnetic orbital susceptibility of Dirac cones
A. Raoux, M. Morigi, J. N. Fuchs +2
We study the orbital susceptibility of coupled energy bands with a pair of Dirac points, as in graphene. We show that different systems having the same zero-field energy spectrum e…
Quantum loss of synchronization in the dynamics of two spins
Y. Liu, F. Piechon, J. N. Fuchs
Motivated by the spin self-rephasing recently observed in an atomic clock, we introduce a simple dynamical model to study the competition between dephasing and synchronization. Two…
Manipulation of Dirac points in graphene-like crystals
R. de Gail, J. -N. Fuchs, M. -O. Goerbig +2
We review different scenarios for the motion and merging of Dirac points in two dimensional crystals. These different types of merging can be classified according to a winding numb…
Extended coherence time on the clock transition of optically trapped Rubidium
G. Kleine Büning, J. Will, W. Ertmer +6
Optically trapped ensembles are of crucial importance for frequency measurements and quantum memories, but generally suffer from strong dephasing due to inhomogeneous density and l…
