Odd-Integer Quantum Hall States and Giant Spin Susceptibility in P -Type Few-Layer WSe₂
(American Physical Society, 2017-02-10)
We fabricate high-mobility p-type few-layer WSe₂ field-effect transistors and surprisingly observe a series of quantum Hall (QH) states following an unconventional sequence predominated by odd-integer states under a moderate ...
Observation of Acoustic Valley Vortex States and Valley-Chirality Locked Beam Splitting
We report an experimental observation of the classical version of valley polarized states in a two-dimensional hexagonal sonic crystal. The acoustic valley states, which carry specific linear momenta and orbital angular ...
Topological Majorana Two-Channel Kondo Effect
(American Physical Society, 2017-10-31)
A one-dimensional time-reversal-invariant topological superconductor hosts a Majorana Kramers pair at each end, where time-reversal symmetry acts as a supersymmetry that flips local fermion parity. We examine the transport ...
