Topological Valley Currents in Gapped Dirac Materials
Yuri D. Lensky, Justin C. W. Song, Polnop Samutpraphoot +1
Gapped 2D Dirac materials, in which inversion symmetry is broken by a gap-opening perturbation, feature a unique valley transport regime. The system ground state hosts dissipationl…
Topological Bloch Bands in Graphene Superlattices
Justin C. W. Song, Polnop Samutpraphoot, Leonid S. Levitov
We outline an approach to endow a plain vanilla material with topological properties by creating topological bands in stacks of manifestly nontopological atomically thin materials.…
Passive intrinsic-linewidth narrowing of ultraviolet extended-cavity diode laser by weak optical feedback
Polnop Samutpraphoot, Sophie Weber, Qian Lin +7
We present a simple method for narrowing the intrinsic Lorentzian linewidth of a commercial ultraviolet grating extended-cavity diode laser (TOPTICA DL Pro) using weak optical feed…
