Persistent Currents in Mesoscopic Connected Rings [PDF]

Physical Review Letters, 2001
We report measurements of the low temperature magnetic response of a line of 16 GaAs/GaAlAs connected mesoscopic rings whose total length is much larger than l(straight phi). Using an on-chip micro-SQUID technology, we have measured a periodic response, with period h/e, corresponding to persistent currents in the rings of a typical amplitude of 0.40 ...

Persistent current noise and electron-electron interactions

, 2011
We analyze fluctuations of persistent current (PC) produced by a charged quantum particle moving in a ring and interacting with a dissipative environment formed by diffusive electron gas.

The current progress of the ALICE Ring Imaging Cherenkov Detector [PDF]

, 2007
Recently, the last two modules (out of seven) of the ALICE High Momentum Particle Identification detector (HMPID) were assembled and tested. The full detector, after a pre-commissioning phase, has been installed in the experimental area, inside the ALICE

Inverse Optically-Induced Ring Currents in Ring-Shaped Molecules

The Journal of Physical Chemistry Letters
Permanent electronic ring currents are supported within manifolds of ΓE degenerate excited electronic states as E± = Ex ± iEy excitations. In [ Phys. Rev. Res. 2021, 3, L042003] we showed the existence of inverse-current manifolds, where the direction of the electronic ring current in each degenerate state E± is opposite to the circular polarization of

A mesoscopic ring as a XNOR gate: An exact result

, 2009
We describe XNOR gate response in a mesoscopic ring threaded by a magnetic flux $\phi$. The ring is attached symmetrically to two semi-infinite one-dimensional metallic electrodes and two gate voltages, viz, $V_a$ and $V_b$, are applied in one arm of the

Switching of +/-360deg domain wall states in a nanoring by an azimuthal Oersted field

, 2011
We demonstrate magnetic switching between two $360^\circ$ domain wall vortex states in cobalt nanorings, which are candidate magnetic states for robust and low power MRAM devices.

Spin Hall Current Driven by Quantum Interferences in Mesoscopic Rashba Rings

, 2004
We propose an all-electrical nanoscopic structure where {\em pure} spin current is induced in the transverse voltage probes attached to {\em quantum-coherent} one-dimensional ring when conventional unpolarized charge current is injected through its ...

Light-induced valley currents and magnetization in graphene rings

, 2009
We study the non-equilibrium dynamics in a mesoscopic graphene ring excited by picoseconds shaped electromagnetic pulses. We predict an ultrafast buildup of charge polarization, currents and orbital magnetization.

Investigating seasonal features of electron temperature enhancement regions in the subauroral ionosphere

Solar-Terrestrial Physics, 2019
The electron temperature enhancement is known to occur in the main ionospheric trough during geomagnetic disturbances. In this paper, we study fea-tures of the formation of the electron temperature (Te) enhancement in the subauroral ionosphere by ...
