Helical Luttinger liquid on a space-time lattice
V. A. Zakharov, J. Tworzydlo, C. W. J. Beenakker +1
The Luttinger model is a paradigm for the breakdown due to interactions of the Fermi liquid description of one-dimensional massless Dirac fermions. Attempts to discretize the model…

Luttinger liquid tensor network: sine versus tangent dispersion of massless Dirac fermions
V. A. Zakharov, S. Polla, A. DonÃs Vela +4
To apply the powerful many-body techniques of tensor networks to massless Dirac fermions one wants to discretize the Hamiltonian and construct a matrix-product-operator…
