Simultaneous mid-infrared quantum cascade laser dual comb Faraday rotation and absorption spectroscopy
Faraday rotation spectroscopy and absorption spectroscopy are performed simultaneously in a dual comb spectroscopy arrangement with quantum cascade laser combs operating at ∼8 μm. The system uses free-running laser combs that provide ∼70 cm−1 spectral …

Resonant photoionization and time delay
Resonances leave prominent signatures in atomic and molecular ionization triggered by the absorption of single or multiple photons. These signatures reveal various aspects of the ionization process, characterizing both the initial and final states of t…

Ro-vibrational dynamics of the neon dimer
Short intense laser pulses are routinely used to induce rotational wave packet dynamics of molecules. Ro-vibrational wave packet dynamics has been explored comparatively infrequently, focusing predominantly on extremely light and rigid molecules such a…

Signature of localization–delocalization in collisional inhomogeneous spin-orbit coupled condensates
We study the localization transition in spin–orbit (SO) coupled binary Bose–Einstein condensates with collisional inhomogeneous interaction trapped in a one-dimensional quasiperiodic potential. Our numerical analysis shows that the competition between …
