Magneto-oscillations, nonlinearity, and nonreciprocity of Coulomb drag in quantum circuits
Alex Levchenko, Mingyang Zheng, Dominique Laroche
We consider the problem of Coulomb drag in interactively coupled quantum circuits built of adiabatic constrictions: quantum point contacts and short quantum-wire channels. The inte…
Temperature-driven transition between momentum-resolved and disordered averaged Coulomb drag in 1D systems
Mingyang Zheng, Rebika Makaju, Rasul Gazizulin +3
Advancing the understanding of electron-electron interactions in one-dimensional systems remains one of the central challenges in low-dimensional physics, especially for Coulomb-co…
Sub-10 mK "In-cell" Magnetic Refrigeration for Cryogen-free Cryostats
Alexander M. Donald, Nicolas Silva, Christopher J. Ollmann +7
A design and implementation of "in-cell" magnetic refrigeration to achieve sub-10 mK temperatures T in cryogen-free dilution refrigerators is presented. The ultra low temperatures…
Non-reciprocal Coulomb drag in a ballistic quantum wire
Suyang Cai, Mingyang Zheng, Nathan Rao +4
1D-Coulomb drag serves as a platform for probing electron-electron interactions in 1D systems. Under the charge fluctuation formalism, the non-reciprocal component of Coulomb drag…
Tunable reciprocal and nonreciprocal contributions to 1D Coulomb Drag
Mingyang Zheng, Rebika Makaju, Rasul Gazizulin +2
Coulomb drag is a powerful tool to study interactions in coupled low-dimensional systems. Historically, Coulomb drag has been attributed to a frictional force arising from momentum…
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…
