Observation of a new three-dimensional Dirac-like dispersion in the type-II Dirac semimetals PtTe2 and PdTe2

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Ivan Pelayo, Derek Bergner, Archibald J. Williams, Jiayuwen Qi, Mahfuzun Nabi | Summary: PtTe$_2$ and PdTe$_2$ are among the first transition metal dichalcogenides that were predicted to host type-II Dirac fermions, exotic particles prohibited in free space. These materials are layered and air-stable, which makes them top […]

Experimental Upper Bounds for Resonance-Enhanced Entangled Two-Photon Absorption Cross Section of Indocyanine Green

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Manni He, Bryce P. Hickam, Nathan Harper, Scott K. Cushing, | Summary: Resonant intermediate states have been proposed to increase the efficiency of entangled two-photon absorption (ETPA). Although resonance-enhanced ETPA (r-ETPA) has been demonstrated in atomic systems using bright squeezed vacuum, it has not been studied […]
