Measure of Diracness in two-dimensional semiconductors
M. O. Goerbig, G. Montambaux, F. Piéchon
We analyze the low-energy properties of two-dimensional direct-gap semiconductors, such as for example the transition-metal dichalcogenides MoS, WS, and their diselenide an…
Magnetic spectrum of trigonally warped bilayer graphene - semiclassical analysis, zero modes, and topological winding numbers
R. de Gail, M. O. Goerbig, G. Montambaux
We investigate the fine structure in the energy spectrum of bilayer graphene in the presence of various stacking defaults, such as a translational or rotational mismatch. This fine…
A semi-Dirac point in the Hofstadter spectrum
P. Delplace, G. Montambaux
The spectrum of tight binding electrons on a square lattice with half a magnetic flux quantum per unit cell exhibits two Dirac points at the band center. We show that, in the prese…
Isolated hybrid normal/superconducting ring in a magnetic flux: from persistent current to Josephson current
J. Cayssol, T. Kontos, G. Montambaux
We investigate the ground state current of an isolated hybrid normal/superconducting ring (NS ring), threaded by an Aharonov-Bohm magnetic flux. We calculate the excitation spectru…
Many-body spectral statistics of interacting Fermions
M. Pascaud, G. Montambaux
We have studied the appearance of chaos in the many-body spectrum of interacting Fermions. The coupling of a single state to the Fermi sea is considered. This state is coupled to a…
Level Curvatures and Conductances: A Numerical Study of the Thouless Relation
D. Braun, E. Hofstetter, G. Montambaux +1
The Thouless conjecture states that the average conductance of a disordered metallic sample in the diffusive regime can be related to the sensitivity of the sample's spectrum to a…
