Inhomogeneous superconductivity in the presence of time-reversal symmetry
We propose a new type of non-uniform condensate state in the presence of
time-reversal symmetry. The underlying platform of this state is a corrugated
honeycomb lattice which exhibits an inhomogeneous pseudo magnetic field. Using
the self-consistent tight-binding Bogoliubov-de Gennes formalism, we show that
an s-wave pairing of chiral carriers in the presence of an inhomogeneous pseudo
magnetic field results in a spatially modulated order parameter with the half
wavelength of the corrugation. The manner of modulation depends on the
fundamental directions of the honeycomb lattice, the zigzag and armchair
directions. The stability of this inhomogeneous superconductivity is also
analyzed and possible experimental realization is discussed.Comment: 6 pages, 6 figure
