Aperiodic Weak Topological Superconductors
I. C. Fulga, D. I. Pikulin, T. A. Loring
Weak topological phases are usually described in terms of protection by the lattice translation symmetry. Their characterization explicitly relies on periodicity since weak invaria…
Scattering matrix invariants of Floquet topological insulators
I. C. Fulga, M. Maksymenko
Similar to static systems, periodically driven systems can host a variety of topologically non-trivial phases. Unlike the case of static Hamiltonians, the topological indices of bu…
Visualization of phase-coherent electron interference in a ballistic graphene Josephson junction
M. T. Allen, O. Shtanko, I. C. Fulga +8
Interference of standing waves in electromagnetic resonators forms the basis of many technologies, from telecommunications and spectroscopy to detection of gravitational waves. How…
PT invariant Weyl semimetals in gauge symmetric systems
L. Lepori, I. C. Fulga, A. Trombettoni +1
Weyl semimetals typically appear in systems in which either time-reversal (T) or inversion (P}) symmetry are broken. Here we show that in the presence of gauge potentials these top…
Spatially resolved edge currents and guided-wave electronic states in graphene
Monica T. Allen, Oles Shtanko, Ion Cosma Fulga +6
A far-reaching goal of graphene research is exploiting the unique properties of carriers to realize extreme nonclassical electronic transport. Of particular interest is harnessing…
Statistical translation invariance protects a topological insulator from interactions
A. Milsted, L. Seabra, I. C. Fulga +2
We investigate the effect of interactions on the stability of a disordered, two-dimensional topological insulator realized as an array of nanowires or chains of magnetic atoms on a…
Gapless Topological Superconductors - Model Hamiltonian and Realization
Yuval Baum, Thore Posske, Ion Cosma Fulga +2
The existence of an excitation gap in the bulk spectrum is one of the most prominent fingerprints of topological phases of matter. In this paper, we propose a family of two dimensi…
