Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity. [PDF]

open access: yesNat Commun, 2015
In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insulator with a band gap.

Measurement Characteristics of Near-Surface Currents from Ultra-Thin Drifters, Drogued Drifters, and HF Radar

open access: yesRemote Sensing, 2018
Concurrent measurements by satellite tracked drifters of different hull and drogue configurations and coastal high-frequency radar reveal substantial differences in estimates of the near-surface velocity.

Increasing the Observability of Near Inertial Oscillations by a Future ODYSEA Satellite Mission

open access: yesRemote Sensing, 2023
Near Inertial Oscillations (NIOs) are ocean oscillations forced by intermittent winds. They are most energetic at mid-latitudes, particularly in regions with atmospheric storm tracks. Wind-driven, large-scale NIOs are quickly scattered by ocean mesoscale

Algebra of chiral currents on the physical surface [PDF]

open access: yes, 2002
Using a particular structure for the Lagrangian action in a one-dimensional Thirring model and performing the Dirac's procedure, we are able to obtain the algebra for chiral currents which is entirely defied on the constraint surface in the corresponding

Anticipated Capabilities of the ODYSEA Wind and Current Mission Concept to Estimate Wind Work at the Air–Sea Interface

open access: yesRemote Sensing, 2023
The kinetic energy transfer between the atmosphere and oceans, called wind work, affects ocean dynamics, including near-inertial oscillations and internal gravity waves, mesoscale eddies, and large-scale zonal jets.

Surface currents and slope selection in crystal growth [PDF]

open access: yes, 2006
We face the problem to determine the slope dependent current during the epitaxial growth process of a crystal surface. This current is proportional to delta=(p+) + (p-), where (p+/-) are the probabilities for an atom landing on a terrace to attach to the

Surface current-carrying domain walls [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1996
Domain walls, arising from the spontaneous breaking of a discrete symmetry, can be coupled to charge carriers. In much the same way as the Witten model for superconducting cosmic string, an investigation is made here in the case of $U(1)\times Z_2 \to U(1)$, where a bosonic charge carrier is directly coupled to the wall-forming Higgs field.

Subset currents on surfaces

open access: yesMemoirs of the American Mathematical Society, 2022
Subset currents on hyperbolic groups were introduced by Kapovich and Nagnibeda as a generalization of geodesic currents on hyperbolic groups, which were introduced by Bonahon and have been successfully studied in the case of the fundamental group π 1 ( Σ ) \pi _1 (\Sigma ) of a ...

Eddy Detection in HF Radar-Derived Surface Currents in the Gulf of Naples

open access: yesRemote Sensing, 2019
Submesoscale eddies play an important role in the energy transfer from the mesoscale down to the dissipative range, as well as in tracer transport. They carry inorganic matter, nutrients and biomass; in addition, they may act as pollutant conveyors ...

Positive currents on non-kählerian surfaces

open access: yesMathematical Research Letters, 2023
We propose a classification of non-k hlerian surfaces from a dynamical point of view and show how the known non-k hlerian surfaces fit into it.
