Feasibility study of continuous electronic Pomeranchuk cooling with a flavor-degenerate Wigner crystal
Robin J. Dolleman, Ammon Fischer, Lennart Klebl +5
Achieving sub-millikelvin electron temperatures in nanoelectronic devices could unveil new transport phenomena, extend quantum coherence times, and enhance the precision of quantum…
Gate-tunable Josephson diodes in magic-angle twisted bilayer graphene
A. Rothstein, R. J. Dolleman, L. Klebl +8
We report low-temperature measurements of two adjacent, gate-defined Josephson junctions (JJs) in magic-angle twisted bilayer graphene (MATBG) at a moiré filling factor near $ν=…
Tailoring hBN's Phonon Polaritons with the Plasmonic Phase-Change Material In3SbTe2
Lina Jäckering, Aaron Moos, Lukas Conrads +8
Polaritons in van-der-Waals materials (vdWM) promise high confinement and multiple tailoring options by optical structures, e.g., resonators, launching structures and lenses. These…
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…
