Z_2-slave-spin theory for strongly correlated fermions
A. Rüegg, S. D. Huber, M. Sigrist
We review a representation of Hubbard-like models that is based on auxiliary pseudospin variables. These pseudospins refer to the local charge modulo two in the original model and…
Effect of a staggered spin-orbit coupling on the occurrence of a nematic phase in SrRuO
Mark H. Fischer, Manfred Sigrist
Ultra-clean crystals of SrRuO undergo a metamagnetic transition at low temperatures. This transition shows a strong anisotropy in the applied field direction with the c…
Influence of the domain walls on the Josephson effect in SrRuO
Adrien Bouhon, Manfred Sigrist
A detailed theoretical interpretation of the Josephson interference experiment between SrRuO and Pb reported by Kidwingira \textit{et al} is given. Assuming chiral p-wave p…
Electronic transport properties of graphene nanoribbons
Katsunori Wakabayashi, Yositake Takane, Masayuki Yamamoto +1
We will present brief overview on the electronic and transport properties of graphene nanoribbons focusing on the effect of edge shapes and impurity scattering. The low-energy elec…
Revisiting the Polar Kerr Effect of a Chiral P-Wave Superconductor
Jonathan M. Buhmann, Manfred Sigrist
This paper has been withdrawn by the authors. Our basic argument on the gauge invariance presented in this paper cannot withstand the criticism which has been drawn to our attentio…
Antiferromagnetic Order and π-triplet Pairing in the Fulde-Ferrell-Larkin-Ovchinnikov State
Youichi Yanase, Manfred Sigrist
The antiferromagnetic Fulde-Ferrell-Larkin-Ovchinnikov (AFM-FFLO) state of coexisting d-wave FFLO superconductivity and incommensurate AFM order is studied on the basis of Bogoliub…
