Diffusion of Dirac fermions across a topological merging transition in two dimensions
P. Adroguer, D. Carpentier, G. Montambaux +1
A continuous deformation of a Hamiltonian possessing at low energy two Dirac points of opposite chiralities can lead to a gap opening by merging of the two Dirac points. In two dim…
Probing (topological) Floquet states through DC transport
Michel Fruchart, Pierre Delplace, Joseph Weston +2
We consider the differential conductance of a periodically driven system connected to infinite electrodes. We focus on the situation where the dissipation occurs predominantly in t…
Minimal conductivity, topological Berry winding and duality in three-band semimetals
Thibaud Louvet, Pierre Delplace, Andrei A. Fedorenko +1
The physics of massless relativistic quantum particles has recently arisen in the electronic properties of solids following the discovery of graphene. Around the accidental crossin…
Construction and properties of a topological index for periodically driven time-reversal invariant 2D crystals
David Carpentier, Pierre Delplace, Michel Fruchart +2
We present mathematical details of the construction of a topological invariant for periodically driven two-dimensional lattice systems with time-reversal symmetry and quasienergy g…
