Electronic Symmetry and Femtosecond Coherence Dynamics of Renner-Teller-Mixed Neutral Vibronic States in Carbon Dioxide
Eric Liu, Shashank Kumar, Siddhant Pandey +7
When non-adiabatic coupling mixes electronic states of a molecule, vibronic states of different electronic symmetry become interleaved across the same spectral region. The symmetry…
Attosecond Control of Squeezed Light
Russell Zimmerman, Shashank Kumar, Shiva Kant Tiwari +9
Squeezed light is a key resource in quantum metrology and quantum information science. It is primarily generated through nonlinear optical interactions, where the degree of squeezi…
Strong-field Driven Sub-cycle Band Structure Modulation and Dephasing Control
Francis Walz, Shashank Kumar, Amirali Sharifi Olounabadi +6
Over the past decade, ultrafast electron dynamics in the solid state have been extensively studied using various strong light-matter interaction techniques, such as high-harmonic g…
Molecular Axis Distribution Moments in Ultrafast Transient Absorption Spectroscopy: A Path Towards Ultrafast Quantum State Tomography
Shashank Kumar, Eric Liu, Liang Z. Tan +2
In ultrafast experiments with gas phase molecules, the alignment of the molecular axis relative to the polarization of the interacting laser pulses plays a crucial role in determin…
