Classification of electromagnetic resonances in finite inhomogeneous three-dimensional structures
Neil V. Budko, Alexander B. Samokhin
We present a simple and unified classification of macroscopic electromagnetic resonances in finite arbitrarily inhomogeneous isotropic dielectric 3D structures situated in free spa…
Parametric coupling for superconducting qubits
P. Bertet, C. J. P. M. Harmans, J. E. Mooij
We propose a scheme to couple two superconducting charge or flux qubits biased at their symmetry points with unequal energy splittings. Modulating the coupling constant between two…
Giant vortices in rotating electron droplets
E. Rasanen, H. Saarikoski, Y. Yu +3
We predict the formation of giant vortices in quasi-two-dimensional quantum dots at high magnetic fields, i.e., in rapidly rotating electron droplets. Our numerical results of quan…
In-Chain Tunneling Through Charge-Density Wave Nanoconstrictions and Break-Junctions
K. O'Neill, E. Slot, R. E. Thorne +1
We have fabricated longitudinal nanoconstrictions in the charge-density wave conductor (CDW) NbSe using a focused ion beam and using a mechanically controlled break-junction…
Tunable Supercurrent Through Semiconductor Nanowires
Yong-Joo Doh, Jorden A. van Dam, Aarnoud L. Roest +3
Nanoscale superconductor-semiconductor hybrid devices are assembled from InAs semiconductor nanowires individually contacted by aluminum-based superconductor electrodes. Below 1 K,…
Tunneling in suspended carbon nanotubes assisted by longitudinal phonons
S. Sapmaz, P. Jarillo-Herrero, Ya. M. Blanter +2
Current-voltage characteristics of suspended single-wall carbon nanotube quantum dots show a series of steps equally spaced in voltage. The energy scale of this harmonic, low-energ…
