One-dimensional topology and topolectrics of nonsymmorphic Kramers degenerate systems
Max Tymczyszyn, Edward McCann
We describe nonsymmorphic four-band tight-binding models in one dimension with Kramers degeneracy, and propose topolectric-circuit realizations of their topological phases. We begi…
One-dimensional topological superconductor
Max Tymczyszyn, Edward McCann
We describe the mean-field model of a one-dimensional topological superconductor with two orbitals per unit cell. Time-reversal symmetry is absent, but a nonsymmorphic symmetry, in…
Zero-energy modes and valley asymmetry in the Hofstadter spectrum of bilayer graphene van der Waals heterostructures with hBN
Xi Chen, J. R. Wallbank, M. Mucha-Kruczynski +2
We investigate the magnetic minibands of a heterostructure consisting of bilayer graphene (BLG) and hexagonal boron nitride (hBN) by numerically diagonalizing a two-band Hamiltonia…
Dirac edges of fractal magnetic minibands in graphene with hexagonal moire superlattices
Xi Chen, J. R. Wallbank, A. A. Patel +3
We find a systematic reappearance of massive Dirac features at the edges of consecutive minibands formed at magnetic fields B_{p/q}= pϕ_0/(qS) providing rational magnetic flux thro…
Evidence for spin memory in the electron phase coherence in graphene
A. A. Kozikov, D. W. Horsell, E. McCann +1
We measure the dependence of the conductivity of graphene as a function of magnetic field, temperature and carrier density and discover a saturation of the dephasing length at low…
Pseudospin valve in bilayer graphene: towards graphene-based pseudospintronics
Pablo San-Jose, Elsa Prada, Edward McCann +1
We propose a non-magnetic, pseudospin-based version of a spin valve, in which the pseudospin polarization in neighboring regions of a graphene bilayer is controlled by external gat…
