Directional Photocurrent Generated by Quantum Interference Control
Yiming Gong, Kai Wang, Steven T. Cundiff
Although the absorption of light in a bulk homogeneous semiconductor produces photocarriers with non-zero momentum, it generally does not produce a current in the absence of an app…

Nonlocal Coherent Optical Nonlinearities of a Macroscopic Quantum System
Albert Liu, Eric W. Martin, Jiaqi Hu +3
The optical responses of solids are typically understood to be local in space. Whether locality holds for the optical response of a macroscopic quantum system has, however, been la…

Quantum Interference Control of Photocurrents in Semiconductors by Nonlinear Optical Absorption Processes
Kai Wang, Rodrigo A. Muniz, J. E. Sipe +1
We report experiments demonstrating Quantum Interference Control (QuIC) based on two nonlinear optical absorption processes in semiconductors. We use two optical beams of frequenci…
