Extreme Polarization of the Optical Gap and High-Energy Exciton Landscape in CrSBr
Sayantan Patra, Sourabh Jain, Bhumika Chauhan +8
We reveal a strongly anisotropic excitonic landscape in monolayer and bulk-like CrSBr using optical absorption spectroscopy and -Bethe-Salpeter equation ca…
Design and fabrication of a micro-ion trap with a 3D-printed loading zone for improved hot-ion capture
Sayan Patra, Abhinav Parakh, Xiaoxing Xia +3
We leverage recent advances in 3D-printing technology to design and fabricate a micro-ion trap with a spatially distinct loading zone for more efficient loading of ions from effusi…
Phonon-modulated Kerr nonlinearity in ultrathin 2H-MoTe2
Shaoxiang Sheng, Yang Luo, Chenyu Wang +8
Controlling nonequilibrium responses in optically driven quantum materials is essential for advancing applications in energy conversion, ultrafast electronics, and quantum computat…
Exciton-Selective Phonon Coupling in a Lead Halide Perovskite
Pradeepa H. L., Sagnik Chatterjee, Sayantan Patra +6
Exciton-phonon interactions govern the optical response of semiconductors, yet disentangling multiple coupling channels in lead halide perovskites remains challenging. We investiga…
