Paramagnetic singularities of the orbital magnetism in graphene with a moiré potential
J. Vallejo Bustamante, R. Ribeiro-Palau, C. Fermon +9
The recent detection of the singular diamagnetism of Dirac electrons in a single graphene layer paved a new way of probing 2D quantum materials through the measurement of equilibri…
Stacking-induced Chern insulator
Marwa Mannaï, Jean-Noël Fuchs, Frédéric Piéchon +1
Graphene can be turned into a semimetal with broken time-reversal symmetry by adding a valley-dependent pseudo-scalar potential that shifts the Dirac point energies in opposite dir…
Orbital embedding and topology of one-dimensional two-band insulators
J. -N. Fuchs, F. Piéchon
The topological invariants of band insulators are usually assumed to depend only on the connectivity between orbitals and not on their intra-cell position (orbital embedding), whic…
Topological and geometrical aspects of band theory
J. Cayssol, J. -N. Fuchs
This paper provides a pedagogical introduction to recent developments in geometrical and topological band theory following the discovery of graphene and topological insulators. Amu…
Wegner-Wilson loops in string nets
A. Ritz-Zwilling, J. -N. Fuchs, J. Vidal
We study the Wegner-Wilson loops in the string-net model of Levin and Wen in the presence of a string tension. The latter is responsible for a phase transition from a topological d…
Parity of Chern numbers in the Kitaev honeycomb model and the sixteenfold way
J. -N. Fuchs, S. Patil, J. Vidal
In two dimensions, topological phases of free Majorana fermions coupled to a gauge field are known to be classified according to the Chern number .…
