Pulsar electrodynamics revisited [PDF]

open access: yes, 2012
The inductive electric field is unjustifiably neglected in most models for pulsar electrodynamics; it cannot be screened by the magnetospheric plasma, and it is not small in comparison with the corotation electric field. The perpendicular component of the inductive electric field implies a drift motion that is inconsistent with corotation at any ...

Electric field metrology for SI traceability: Systematic measurement uncertainties in electromagnetically induced transparency in atomic vapor

open access: yes, 2017
We investigate the relationship between the Rabi frequency (ΩRF, related to the applied electric field) and Autler-Townes (AT) splitting, when performing atom-based radio-frequency (RF) electric (E) field strength measurements using Rydberg states and ...

Electronic structure of unidirectional superlattices in crossed electric and magnetic fields and related terahertz oscillations

open access: yes, 2007
We have studied Bloch electrons in a perfect unidirectional superlattice subject to crossed electric and magnetic fields, where the magnetic field is oriented ``in-plane'', i.e. in parallel to the sample plane.

Generation of Advanced Blood–Brain Barrier Spheroids Using Human‐Induced Pluripotent Stem Cell‐Derived Brain Capillary Endothelial‐Like Cells

open access: yesAdvanced Biology, EarlyView.
In this article, the establishment and characterization of a self‐assembled 3D BBB spheroid model using human induced pluripotent stem cell (hiPSC)‐derived and primary cells is reported. Spheroids demonstrate in‐vivo like tight junction ultrastructure and, in comparison to 2D mono‐cultures, higher transcript expression of BBB specific genes.

Klein-Gordon equations with homogeneous time-dependent electric fields [PDF]

open access: yes, 2017
We consider a system associated to Klein-Gordon equations with homogeneous time-dependent electric fields. The upper and lower boundaries of a time-evolution propagator for this system were proven by Veseli\'c in 1991 for electric fields that are independent of time. We extend this result to time-dependent electric fields.

Enhanced Sensitivity in Rydberg Atom Electric Field Sensors through Autler-Townes Effect and Two-Photon Absorption: A Theoretical Analysis Using Many-Mode Floquet Theory [PDF]

open access: yesarXiv, 2023
In this paper, we present a comprehensive investigation into the sensitivity of a Rydberg atom electric field sensor, with a specific focus on the minimum detectable field (MDF) as a key metric. The study utilizes one-mode Floquet theory to calculate the Stark shift for selected Rydberg states when exposed to a signal electric field.

Pumping spin with electrical fields [PDF]

open access: yesPhysical Review B, 2003
Spin currents can be obtained through adiabatic pumping by means of electrical gating only. This is possible by making use of the tunability of the Rashba spin-orbit coupling in semiconductor heterostructures. We demonstrate the principles of this effect by considering a single-channel wire with a constriction.
