Superconducting Nanoelectromechanical Transducer Resilient to Magnetic Fields
Jinwoong Cha, Hak-Seong Kim, Jihwan Kim +2
Nanoscale electromechanical coupling provides a unique route towards control of mechanical motions and microwave fields in superconducting cavity electromechanical devices. Though…
Nanomechanical characterization of quantum interference in a topological insulator nanowire
Minjin Kim, Jihwan Kim, Yasen Hou +5
The discovery of two-dimensional gapless Dirac fermions in graphene and topological insulators (TI) has sparked extensive ongoing research toward applications of their unique elect…
Dissipation-driven nonclassical state generation in optomechanics with squeezed light
Jae Hoon Lee, Junho Suh, Hyojun Seok
We study an optomechanical system for the purpose of generating a nonclassical mechanical state when a mechanical oscillator is quadratically coupled to a single-mode cavity field…
Interplay between superconductivity and magnetism in one-unit-cell LaAlO3 capped with SrTiO3
Yongsu Kwak, Woojoo Han, Thach D. N. Ngo +13
To form a conducting layer at the interface between the oxide insulators LaAlO3 and SrTiO3, the LaAlO3 layer on the SrTiO3 substrate must be at least four unit-cells-thick. The LaA…
Directly Detecting the Edge Current in a Topological Superfluid
HeeSu Byun, Jinhoon Jeong, Kitak Kim +4
Topological superconductors are one of the most actively studied materials these days. They are a promising candidate for hosting Majorana fermions either on their boundaries or in…
Quantum squeezing of motion in a mechanical resonator
E. E. Wollman, C. U. Lei, A. J. Weinstein +5
As a result of the quantum, wave-like nature of the physical world, a harmonic oscillator can never be completely at rest. Even in the quantum ground state, its position will alway…
