Nature of the Quantum Metal in a Two-Dimensional Crystalline Superconductor
A. W. Tsen, B. Hunt, Y. D. Kim +7
Two-dimensional (2D) materials are not expected to be metals at low temperature due to electron localization. Consistent with this, pioneering studies on thin films reported only s…
Interplay of Rotational, Relaxational, and Shear Dynamics in Solid 4He
E. J. Pratt, B. Hunt, V. Gadagkar +4
Using a high-sensitivity torsional oscillator technique, we mapped the rotational and relaxational dynamics of solid helium-4 throughout the parameter range of the proposed superso…
Heterotic/Type II Duality in D=4 and String/String Duality
B. Hunt, M. Lynker, R. Schimmrigk
We discuss the structure of heterotic/type II duality in four dimensions as a consequence of string-string duality in six dimensions. We emphasize the new features in four dimensio…
Charged bosons made of fermions in a solid state system without Cooper pairing
Z. Sun, J. Beaumariage, Q. Wan +9
We report experimental evidence for charged boson states in a solid without Cooper pairing, based on attaching two free carriers to an exciton in a semiconducting system. Theoretic…
Tunable symmetry breaking and helical edge transport in a graphene quantum spin Hall state
A. F. Young, J. D. Sanchez-Yamagishi, B. Hunt +5
Low-dimensional electronic systems have traditionally been obtained by electrostatically confining electrons, either in heterostructures or in intrinsically nanoscale materials suc…
Observation of Helical Edge States and Fractional Quantum Hall Effect in a Graphene Electron-hole Bilayer
J. D. Sanchez-Yamagishi, J. Y. Luo, A. F. Young +5
A quantum Hall edge state provides a rich foundation to study electrons in 1-dimension (1d) but is limited to chiral propagation along a single direction. Here, we demonstrate a ve…
