AI Article Synopsis
- The study measures the Stark shift of the A2Pi(1/2)-X2Sigma+ transition in YbF using a molecular beam triple resonance technique, involving two lasers and an rf transition.
- After accounting for the known ground state Stark shift, the research finds the static electric polarizability of the A2Pi(1/2) state to be 70.3(1.5) Hz/(V/cm)² over an applied electric field range of 0-5 kV/cm.
- A detailed analysis leads to the determination of the electric dipole moment of the A2Pi(1/2)(v=0) state, calculated as mu(e)=2.48(3) D.
Article Abstract
We have measured the Stark shift of the A2Pi(1/2)-X2Sigma+ transition in YbF. We use a molecular beam triple resonance method, with two laser transitions acting as pump and probe, assisted by an rf transition that tags a single hyperfine transition of the X state. After subtracting the known ground state Stark shift, we obtain a value of 70.3(1.5) Hz/(V/cm)2 for the static electric polarizability of the state A2Pi(1/2) (J=1/2),f by fitting our data to a purely quadratic Stark shift in the interval 0-5 kV/cm. A more exact analysis that does not assume a perfectly quadratic Stark effect yields the value mu(e)=2.48(3) D for the electric dipole moment of the A2Pi(1/2)(v=0) state.

Fermi polarons are emerging quasiparticles when a bosonic impurity immersed in a fermionic bath. Depending on the boson-fermion interaction strength, the Fermi-polaron resonances exhibit either attractive or repulsive interactions, which impose further experimental challenges on understanding the subtle light-driven dynamics. Here, we report the light-driven dynamics of attractive and repulsive Fermi polarons in monolayer WSe devices.

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns. Changes in the housing environment in particular may have critical influences on behaviour and welfare.

Background: The onset of the COVID-19 pandemic brought about a stark and devastating impact on global scales, affecting countries and their citizens profoundly. The public's lack of readiness for such an enigmatic and virulent threat led to widespread alarm, catalyzing a paradigm shift in both public conduct and governmental tactics. In the midst of this urgency, there was a notable lack of studies on the initial panic waves.

Article Synopsis
- * We observe a blue Stark shift in energy levels for formal topological states, while the interface states exhibit an oscillatory Stark shift around the Fermi level.
- * Our findings highlight the impact of the Stark effect on transmission coefficients and suggest that electric fields can control coupling strength in topological interface states, offering insights for future electronic devices and quantum technologies.

Intersubband transitions in semiconductor heterostructures offer a way to achieve large and designable nonlinearities with dynamic modulation of intersubband energies through the Stark effect. One promising approach for incorporating these nonlinearities into free space optics is a nonlinear polaritonic metasurface, which derives resonant coupling between intersubband nonlinearities and optical modes in nanocavities. Recent work has shown efficient frequency mixing at low pumping intensities, with the ability to electrically tune the phase, amplitude, and spectral peak of it.
