Vortex arrays in a rotating superfluid He-4 nanocylinder
Francesco Ancilotto, Marti Pi, Manuel Barranco
Within Density Functional theory, we investigate stationary many-vortex structures in a rotating He nanocylinder at zero temperature. We compute the stability diagram and compa…
Electrical Control of Optical Emitter Relaxation Pathways enabled by Graphene
K. J. Tielrooij, L. Orona, A. Ferrier +16
Controlling the energy flow processes and the associated energy relaxation rates of a light emitter is of high fundamental interest, and has many applications in the fields of quan…
Theory of coupled spin-charge transport due to spin-orbit interaction in inhomogeneous two-dimensional electron liquids
K. Shen, R. Raimondi, G. Vignale
Spin-orbit interactions in two-dimensional electron liquids are responsible for many interesting transport phenomena in which particle currents are converted to spin polarizations…
Phase separation and long wave-length charge instabilities in spin-orbit coupled systems
G. Seibold, D. Bucheli, S. Caprara +1
We investigate a two-dimensional electron model with Rashba spin-orbit interaction where the coupling constant depends on the electronic density. It is shown that this dep…
Micro-Raman and field emission studies of silicon nanowires prepared by metal assisted chemical etching
Vivek Kumar, Shailendra K. Saxena, Vishakha Kaushik +3
Micro-Raman scattering and electron field emission characteristics of silicon nanowires (SiNWs) synthesized by metal assisted chemical etching (MACE) are investigated. Scanning ele…
Symmetries and selection rules in the measurement of the phonon spectrum of graphene and related materials
Fernando de Juan, Antonio Politano, Gennaro Chiarello +1
When the phonon spectrum of a material is measured in a scattering experiment, selection rules preclude the observation of phonons that are odd under reflection by the scattering p…
