Contactless cavity sensing of superfluid stiffness in atomically thin 4Hb-TaS
Trevor Chistolini, Ha-Leem Kim, Qiyu Wang +13
The exceptional tunability of two-dimensional van der Waals materials offers unique opportunities for exploring novel superconducting phases. However, in such systems, the measurem…
Terahertz electrodynamics in a zero-field Wigner crystal
Su-Di Chen, Ruishi Qi, Ha-Leem Kim +8
In clean two-dimensional (2D) systems, electrons are expected to self-organize into a regular lattice, a Wigner crystal, when their mutual Coulomb repulsion overwhelms kinetic ener…
Orbital dependent Coulomb drag in electron-hole bilayer graphene heterostructures
Zuocheng Zhang, Ruishi Qi, Jingxu Xie +5
We report Coulomb drag studies in an electron-hole bilayer graphene heterostructure in a magnetic field, where the orbital, spin, and valley degrees of freedom are lifted by the co…
Competition between excitonic insulators and quantum Hall states in correlated electron-hole bilayers
Ruishi Qi, Qize Li, Zuocheng Zhang +11
Excitonic insulators represent a unique quantum phase of matter, providing a rich ground for studying exotic quantum bosonic states. Strongly coupled electron-hole bilayers, which…
