Spin wave calculation of the field-dependent magnetization pattern around an impurity in Heisenberg antiferromagnets
Sergey Shinkevich, Olav F. Syljuåsen, Sebastian Eggert
We consider the magnetic-field dependent spatial magnetization pattern around a general impurity embedded in a Heisenberg antiferromagnet using both an analytical and a numerical s…
Non-Collinear Ferromagnetic Luttinger Liquids
Nicholas Sedlmayr, Sebastian Eggert, Jesko Sirker
The presence of electron-electron interactions in one dimension profoundly changes the properties of a system. The separation of charge and spin degrees of freedom is just one exam…
Dynamics and decoherence in the central spin model using exact methods
Michael Bortz, Sebastian Eggert, Christian Schneider +2
The dynamics and decoherence of an electronic spin-1/2 qubit coupled to a bath of nuclear spins via hyperfine interactions in a quantum dot is studied. We show how exact results fr…
Static impurities in a supersolid of interacting hard-core bosons on a triangular lattice
Xue-Feng Zhang, Yu-Chuan Wen, Sebastian Eggert
We study the effect of impurities in a supersolid phase in comparison to the behavior in the solid and superfluid phases. A supersolid phase has been established for interacting ha…
