Magnetically induced current densities in phenylenes in the ground and lowest lying triplet excited states [PDF]

open access: yesKragujevac Journal of Science
Magnetically induced current densities in the lowest lying singlet and triplet states of a series of phenylene molecules were examined at the B3LYP/lanl2DZ level of theory. Previous findings have shown that in the ground singlet state, phenylenes exhibit

Currents and pseudomagnetic fields in strained graphene rings [PDF]

open access: yes, 2013
We study the effects of strain on the electronic properties and persistent current characteristics of a graphene ring using the Dirac representation. For a slightly deformed graphene ring flake, one obtains sizable pseudomagnetic (gauge) fields that may ...

SuperKEKB vacuum system operation in the last 6 years operation

open access: yesPhysical Review Accelerators and Beams, 2023
The operation of the SuperKEKB has been ongoing since 2016. The vacuum systems of the main ring (MR) which consists of a 7-GeV electron ring (HER) and a 4-GeV positron ring (LER), the damping ring (DR) for 1.1 GeV positrons in the middle of the injector ...

Relation between the asymmetric ring current effect and the anti-sunward auroral currents, as deduced from CHAMP observations [PDF]

open access: yesAnnales Geophysicae, 2020
During magnetically active periods the storm-time disturbance signal on the ground commonly develops an azimuthal asymmetry. Negative deflections of the magnetic horizontal (H) component are enhanced in the 18:00 local time sector and smallest in the ...

Current magnification effect in mesoscopic systems at equilibrium [PDF]

open access: yes, 2001
We study the current magnification effect and associated circulating currents in mesoscopic systems at equilibrium. Earlier studies have revealed that in the presence of transport current(non-equilibrium situation), circulating currents can flow in a ...

Ring Current Decay

open access: yesJournal of geomagnetism and geoelectricity, 1991
The terrestrial ring current decays dominantly by charge exchange but Coulomb collisions and wave-particle interactions are also important processes in the overall decay and produce interesting thermal plasma effects. Charge exchange results in energetic neutral atom precipitation over a broad region; Coulomb collisions and wave-particle interactions ...

Opportunities for detecting ring currents using an attoclock setup [PDF]

open access: yes, 2015
Strong field ionization by circularly polarized laser fields from initial states with internal orbital momentum has interesting propensity rule: electrons counter-rotating with respect to the laser field can be liberated more easily than co-rotating ...

Defining and resolving current systems in geospace [PDF]

open access: yesAnnales Geophysicae, 2015
Electric currents flowing through near-Earth space (R ≤ 12 RE) can support a highly distorted magnetic field topology, changing particle drift paths and therefore having a nonlinear feedback on the currents themselves.

Ring currents in azulene [PDF]

open access: yesChemical Physics Letters, 2009
We propose a self consistent polarisable ion tight binding theory for the study of push–pull processes in aromatic molecules. We find that the method quantitatively reproduces ab initio calculations of dipole moments and polarisability. We apply the scheme in a simulation which solves the time dependent Schrodinger equation to follow the relaxation of ...
