Fermi surface of the chiral topological semimetal CoSi
Nico Huber, Sanu Mishra, Ilya Sheikin +6
We report a study of the Fermi surface of the chiral semimetal CoSi and its relationship to a network of multifold topological crossing points,Weyl points, and topological nodal pl…

Perturbative description of high- superconductivity in the Hubbard model via unitary transformation and classical spins
Kirill Alpin
A unitary transformation is applied to the Hubbard model, which maps the Hubbard interaction to a single particle term. The resulting Hamiltonian consists of unconstrained fermions…
