Angle evolution of the superconducting phase diagram in twisted bilayer WSe2
Yinjie Guo, John Cenker, Ammon Fischer +13
Recent observations of superconductivity in twisted bilayer WSe have extended the family of moiré superconductors beyond twisted graphene. In WSe two different twist angles…
Numerical investigation of electrostatically confined excitons in monolayer
Lefan Dolg, Moritz Scharfstädt, Andrea Bergschneider +2
We investigate exciton confinement to a quantum wire in monolayer where the confinement is achieved by a p-i-n junction. We employ an effective-mass exciton model a…
Anyonic Chern insulator in graphene induced by surface electromagnon vacuum fluctuations
Xinle Cheng, Emil Viñas Boström, Frank Y. Gao +3
Sub-wavelength cavities have emerged as a promising platform to realize strong light-matter coupling in condensed matter systems. Previous studies are limited to dielectric sub-wav…
Imaging van Hove Singularity Heterogeneity in Overdoped Graphene
Raymond Blackwell, Zengyi Du, Takuya Okugawa +7
Tuning the chemical potential of a solid to the vicinity of a van Hove singularity (vHS) is a well-established route to discovering emergent quantum phases. In monolayer graphene,…
Nonperturbative Nonlinear Transport in a Floquet-Weyl Semimetal
Matthew W. Day, Kateryna Kusyak, Felix Sturm +23
Periodic laser driving, known as Floquet engineering, is a powerful tool to manipulate the properties of quantum materials. Using circularly polarized light, artificial magnetic fi…
Gate-defined single-electron transistors in twisted bilayer graphene
Alexander Rothstein, Ammon Fischer, Anthony Achtermann +12
Twisted bilayer graphene (tBLG) near the magic angle is a unique platform where the combination of topology and strong correlations gives rise to exotic electronic phases. These ph…
