Singular flat bands in the modified Haldane-Dice model
Alexander Filusch, Holger Fehske
Flat bands can be divided into singular and non-singular ones according to the behavior of their Bloch wave function around band-crossing points in momentum space. We analyze the f…
Tunable valley filtering in dynamically strained - lattices
Alexander Filusch, Holger Fehske
Mechanical deformations in - lattices induce local pseudomagnetic fields of opposite directionality for different valleys. When this strain is equipped with a dyn…
Valley filtering in strain-induced - quantum dots
Alexander Filusch, Alan R. Bishop, Avadh Saxena +2
We test the valley-filtering capabilities of a quantum dot inscribed by locally straining an - lattice. Specifically, we consider an out-of-plane Gaussian bump in…
Electronic Properties of Quantum Dots in Magnetic Fields
Alexander Filusch, Holger Fehske
We address the electronic properties of quantum dots in the two-dimensional lattice when subjected to a perpendicular magnetic field. Implementing an infinite mas…
Resonant scattering of Dice quasiparticles on oscillating quantum dots
Alexander Filusch, Christian Wurl, Holger Fehske
We consider a Dice model with Dirac cones intersected by a topologically flat band at the charge neutrality point and analyze the inelastic scattering of massless pseudospin-1 part…
Transport and quantum coherence in graphene rings: Aharonov-Bohm oscillations, Klein tunneling and particle localization
Alexander Filusch, Christian Wurl, Andreas Pieper +1
Simulating quantum transport through mesoscopic, ring-shaped graphene structures, we address various quantum coherence and interference phenomena. First, a perpendicular magnetic f…
