Discrete states and ballistic interference in quantum wires approaching macroscopic lengths
Henok Weldeyesus, Taras Patlatiuk, Christian P. Scheller +4
Increasing the size of a system showing quantum effects is a difficult task limited by decoherence, a diminishing quantum level spacing, and the effects of disorder spoiling the qu…
Magnetic Field-Enhanced Graphene Superconductivity with Record Pauli-Limit Violation
Jixiang Yang, Omid Sharifi Sedeh, Chiho Yoon +22
Spin-polarized superconductors offer a rare platform for studying electronic correlations, but few candidate systems have been experimentally confirmed to date. Here, we report the…
Family of Unconventional Superconductivities in Crystalline Graphene
Junseok Seo, Armel A. Cotten, Mingchi Xu +17
Unconventional superconductors exhibit multiple broken symmetries and exceed the range of the Bardeen-Cooper-Schrieffer (BCS) theory. For instance, time-reversal symmetry can be br…
Dominant end-tunneling effect in two distinct Luttinger liquids coexisting in one quantum wire
Henok Weldeyesus, Pedro M. T. Vianez, Omid Sharifi Sedeh +10
Luttinger liquids occupy a special place in physics as the most understood case of essentially quantum many-body systems. The experimental mission of measuring its main prediction,…
Finite-bias Coulomb blockade thermometry
Omid Sharifi Sedeh, Christian P. Scheller, Henok Weldeyesus +4
Coulomb blockade thermometers (CBTs) are versatile and, in principle, primary thermometers operating down to the micro-Kelvin range but bias heating spoils the thermometry and the…
Signatures of Chiral Superconductivity in Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Zach Hadjri +20
Chiral superconductors are unconventional superconducting states that break time reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.…
