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.
