Optical signatures of antiferromagnetic correlations in a strongly interacting quantum Hall MoSe2 monolayer
Jiho Sung, Pavel A. Volkov, Ilya Esterlis +9
Strong magnetic fields quench the kinetic energy of electrons, leading to the formation of flat energy bands, known as Landau levels (LLs). In this situation, even weak interaction…
A scalable platform for nanometer-scale quantum confinement
Christina M. Spaegele, Mehdi Rezaee, Thomas Werkmeister +8
Overcoming the limitations of current nanofabrication techniques to achieve nanoscale feature sizes is essential for achieving new regimes of light-matter interactions at extreme f…
Interlayer exciton condensates between second Landau level orbitals in double bilayer graphene
Zeyu Hao, A. M. Zimmerman, Kenji Watanabe +2
We present Coulomb-drag measurements on a heterostructure comprising two Bernal-stacked bilayer graphene (BLG) sheets separated by a 2.5 nm hexagonal boron nitride (hBN) spacer in…
Unconventional domain tessellations in moiré-of-moiré lattices
Daesung Park, Changwon Park, Kunihiro Yananose +18
Imposing incommensurable periodicity on the periodic atomic lattice can lead to complex structural phases consisting of locally periodic structure bounded by topological defects. T…
Modulation of superconductivity across a Lifshitz transition in alternating-angle twisted quadrilayer graphene
Isabelle Y. Phinney, Andrew Zimmerman, Zeyu Hao +5
We report electric field-controlled modulation of the Fermi surface topology and explore its effects on the superconducting state in alternating-angle twisted quadrilayer graphene…
