Nanomechanics driven by the superconducting proximity effect
O. M. Bahrova, S. I. Kulinich, L. Y. Gorelik +2
We consider a nanoelectromechanical weak link composed of a carbon nanotube suspended above a trench in a normal metal electrode and positioned in a gap between two superconducting…
Polaronic effects induced by non-equilibrium vibrons in a single-molecule transistor
O. M. Bahrova, S. I. Kulinich, I. V. Krive
Current-voltage characteristics of a single-electron transistor with a vibrating quantum dot were calculated assuming vibrons to be in a coherent (non-equilibrium) state. For a lar…
A strain-engineered graphene qubit in a nanobubble
Nojoon Myoung, JungYun Han, Hee Chul Park
We propose a controllable qubit in a graphene nanobubble with emergent two-level systems induced by pseudo-magnetic fields. We found that double quantum dots can be created by the…
Observation of the orbital Hall effect in a light metal Ti
Young-Gwan Choi, Daegeun Jo, Kyung-Hun Ko +7
The orbital angular momentum is a core ingredient of orbital magnetism, spin Hall effect, giant Rashba spin splitting, orbital Edelstein effect, and spin-orbit torque. However, its…
Valley protected one-dimensional states in small-angle twisted bilayer graphene
J. D. Verbakel, Q. Yao, K. Sotthewes +1
Theory predicts that the application of an electric field breaks the inversion symmetry of AB and BA stacked domains in twisted bilayer graphene, resulting in the formation of a tr…
Strong interlayer coupling and stable topological flat bands in twisted bilayer photonic Moire superlattices
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
The moiré superlattice of misaligned atomic bilayers paves the way for designing a new class of materials with wide tunability. In this work, we propose a photonic analog of the mo…
