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…
Observation of two-component exciton condensates in an excitonic insulator
Ruishi Qi, Qize Li, Jiahui Nie +9
Macroscopic quantum coherence emerges when bosons condense into a Bose-Einstein condensate (BEC). First observed as a single-component superfluid in helium, BECs later emerged in u…
Observation of an exciton crystal in a moiré excitonic insulator
Ruishi Qi, Qize Li, Haleem Kim +9
Strong Coulomb interactions can drive electrons to crystallize into a Wigner lattice. Achieving the bosonic analogue - a crystal of excitons - has remained elusive due to their sho…
Visualizing the Impact of Quenched Disorder on 2D Electron Wigner Solids
Zhehao Ge, Conor Smith, Zehao He +17
Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem…
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…
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…
