Vortices, zero modes and fractionalization in bilayer-graphene exciton condensate
B. Seradjeh, H. Weber, M. Franz
A real-space formulation is given for the recently discussed exciton condensate in a symmetrically biased graphene bilayer. We show that in the continuum limit an oddly-quantized v…

Heavy-fermion metals with hybridization nodes: Unconventional Fermi liquids and competing phases
Heidrun Weber, Matthias Vojta
Microscopic models for heavy-fermion materials often assume a local, i.e., momentum-independent, hybridization between the conduction band and the local-moment f electrons. Motivat…

A mean-field theory for strongly disordered non-frustrated antiferromagnets
Heidrun Weber, Matthias Vojta
Motivated by impurity-induced magnetic ordering phenomena in spin-gap materials like TlCuCl3, we develop a mean-field theory for strongly disordered antiferromagnets, designed to c…
