Methods to discretize the Hamiltonian of a topological insulator or topological
superconductor, without giving up on the topological protection of the massless excitations …

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 on …

The electromagnetic Casimir effect has a fermionic counterpart in topological insulators:
Zero-point fluctuations of a massless Dirac fermion field mediate a force between magnetic …

To apply the powerful many-body techniques of tensor networks to massless Dirac fermions,
one wants to discretize the p· σ Hamiltonian and construct a matrix-product-operator (MPO) …

The spectrum of massless Dirac fermions on the surface of a topological insulator in a
perpendicular magnetic field B contains a B-independent “zeroth Landau level”, protected …

A fundamental concept in condensed matter physics is that the effective behavior of
electrons is strongly influenced by the medium in which they exist. An example of this is …
