Energy Time Ptychography for one-dimensional phase retrieval

Ankita Negi, Leon Merten Lohse, Sven Velten +9

Phase retrieval is at the heart of adaptive optics and modern high-resolution imaging. Without phase information, optical systems are limited to intensity-only measurements, hinder…

Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption

Wenqing Li, Xiaosong Zhu, Pengfei Lan +5

We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorptio…

Picocavity-Enhanced Raman Spectroscopy of Physisorbed H and D Molecules

Akitoshi Shiotari, Shuyi Liu, George Trenins +4

We report on tip-enhanced Raman spectroscopy of H2 and D2 molecules physisorbed within a plasmonic picocavity at 10 K. The intense Raman peaks resulting from the rotational and vib…

Terahertz chiral photonic-crystal cavities for Dirac gap engineering in graphene

Fuyang Tay, Stephen Sanders, Andrey Baydin +6

Strong coupling between matter and vacuum electromagnetic fields in a cavity can induce novel quantum phases in thermal equilibrium via symmetry breaking. Particularly intriguing i…
