Optical Conductivity Signatures of Floquet Electronic Phases
Andrew Cupo, Joshuah T. Heath, Emilio Cobanera +3
Optical conductivity measurements may provide access to distinct signatures of Floquet electronic phases, which are described theoretically by their quasienergy band structures. We…
Floquet Graphene Antidot Lattices
Andrew Cupo, Emilio Cobanera, James D. Whitfield +2
We establish the theoretical foundation of the Floquet graphene antidot lattice, whereby massless Dirac fermions are driven periodically by a circularly polarized electromagnetic f…
Bloch and Bethe ansatze for the Harper model: A butterfly with a boundary
Qiao-Ru Xu, Emilio Cobanera, Gerardo Ortiz
Based on a recent generalization of Bloch's theorem, we present a Bloch ansatz for the Harper model with an arbitrary rational magnetic flux in various geometries, and solve the as…
Squaring the fermion: The threefold way and the fate of zero modes
Qiao-Ru Xu, Vincent P. Flynn, Abhijeet Alase +3
We investigate topological properties and classification of mean-field theories of stable bosonic systems. Of the three standard classifying symmetries, only time-reversal represen…
Quantum Brownian motion in a Landau level
Emilio Cobanera, Peter Kristel, Cristiane Morais Smith
Motivated by questions about the open-system dynamics of topological quantum matter, we investigated the quantum Brownian motion of an electron in a homogeneous magnetic field. Whe…
Thermodynamic signatures of edge states in topological insulators
Anton Quelle, Emilio Cobanera, Cristiane Morais Smith
Topological insulators are states of matter distinguished by the presence of symmetry protected metallic boundary states. These edge modes have been characterised in terms of trans…
Changing anyonic ground degeneracy with engineered gauge fields
Emilio Cobanera, Jascha Ulrich, Fabian Hassler
For systems of lattice anyons like Majorana and parafermions, the unconventional quantum statistics determines a set of global symmetries (e.g., fermion parity for Majoranas) admit…
Equivalence of Topological Insulators and Superconductors
E. Cobanera, G. Ortiz
Systems of free fermions are classified by symmetry, space dimensionality, and topological properties described by K-homology. Those systems belonging to different classes are ineq…
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…
Giant negative magnetoresistance driven by spin-orbit coupling at the LAO/STO interface
M. Diez, A. M. R. V. L. Monteiro, G. Mattoni +6
The LAO/STO interface hosts a two-dimensional electron system that is unusually sensitive to the application of an in-plane magnetic field. Low-temperature experiments have reveale…
Many-body characterization of topological superconductivity: The Richardson-Gaudin-Kitaev chain
Gerardo Ortiz, Jorge Dukelsky, Emilio Cobanera +2
What distinguishes trivial from topological superluids in interacting many-body systems where the number of particles is conserved? Building on a class of integrable pairing Hamilt…
Thermal conductance as a probe of the non-local order parameter for a topological superconductor with gauge fluctuations
B. van Heck, E. Cobanera, J. Ulrich +1
We investigate the effect of quantum phase slips on a helical quantum wire coupled to a superconductor by proximity. The effective low-energy description of the wire is that of a M…
Arbitrary Dimensional Majorana Dualities and Network Architectures for Topological Matter
Zohar Nussinov, Gerardo Ortiz, Emilio Cobanera
Motivated by the prospect of attaining Majorana modes at the ends of nanowires, we analyze interacting Majorana systems on general networks and lattices in an arbitrary number of d…
