Impurity Effects in Highly Frustrated Diamond Lattice Antiferromagnets
Lucile Savary, Emanuel Gull, Simon Trebst +3
We consider the effects of local impurities in highly frustrated diamond lattice antiferromagnets, which exhibit large but non-extensive ground state degeneracies. Such models are…
Axion response in gapless systems
Doron L. Bergman
The strong topological insulator in 3D is expected to realize a quantized magneto-electric response, the so-called axion response. However, many of the materials predicted to be to…
Theory of dissipationless Nernst effects
Doron Bergman, Vadim Oganesyan
We develop a theory of transverse thermoelectric (Peltier) conductivity, α_{xy}, in finite magnetic field -- this particular conductivity is often the most important contribution t…
Band touching from real space topology in frustrated hopping models
Doron L. Bergman, Congjun Wu, Leon Balents
We study ``frustrated'' hopping models, in which at least one energy band, at the maximum or minimum of the spectrum, is dispersionless. The states of the flat band(s) can be repre…
The -orbital counterpart of graphene: cold atoms in the honeycomb optical lattice
Congjun Wu, S. Das Sarma
We study the ground state properties of the interacting spinless fermions in the -orbital bands in the two dimensional honeycomb optical lattice, which exhibit different n…
Flat bands and Wigner crystallization in the honeycomb optical lattice
Congjun Wu, Doron Bergman, Leon Balents +1
We study the ground states of cold atoms in the tight-binding bands built from p-orbitals on a two dimensional honeycomb optical lattice. The band structure includes two completely…
