Violation of Pauli Limit at KTaO3(110) Interfaces
Samuel J. Poage, Xueshi Gao, Merve Baksi +7
The superconducting order parameter at the KTaO3 interfaces and its dependence on interface orientation remains a subject of debate. The superconductivity at these interfaces exhib…
Dominant 1/3-filling Correlated Insulator States and Orbital Geometric Frustration in Twisted Bilayer Graphene
Haidong Tian, Emilio Codecido, Dan Mao +8
Geometric frustration is a phenomenon in a lattice system where not all interactions can be satisfied, the simplest example being antiferromagnetically coupled spins on a triangula…
Giant Tunability of Intersubband Transitions and Quantum Hall Quartets in Few-Layer InSe Quantum Wells
Dmitry Shcherbakov, Greyson Voigt, Shahriar Memaran +8
A two-dimensional (2D) quantum electron system is characterized by the quantized energy levels, or subbands, in the out-of-plane direction. Populating higher subbands and controlli…
Thickness and twist angle dependent interlayer excitons in metal monochalcogenide heterostructures
