Characterization of two electronic subsystems in cuprates through optical conductivity
Understanding the physical properties of unconventional superconductors as well as of other correlated materials presents a formidable challenge. Their unusual evolution with doping, frequency, and temperature has frequently led to non-Fermi-liquid (non-FL ...
2023Optical Diffraction Tomography Using Nearly In-Line Holography with a Broadband LED Source
Demetri Psaltis, Abhijit Roy, Ahmed Ayoub
We present optical tomography methods for a 3D refractive index reconstruction of weakly scattering objects using LED light sources. We are able to record holograms by minimizing the optical path difference between the signal and reference beams while sepa ...
MDPI2022Comparison between CIE 2° and 10° field photopic luminosity functions V(λ) for calculating daylight discomfort glare metrics
Marilyne Andersen, Jan Wienold, Sneha Jain
The spectral sensitivity of the average human eye in photopic conditions is represented by the photopic luminosity function V (λ). The CIE has established the photopic luminosity functions for the 2o and 10o visual fields for a standard observer applicable ...
2022Room-temperature electrical control of polarization and emission angle in a cavity-integrated 2D pulsed LED
Andras Kis, Fedele Tagarelli, Dmitrii Unuchek, Zhe Sun, Juan Francisco Gonzalez Marin, Cheol Yeon Cheon
Devices based on two-dimensional (2D) semiconductors hold promise for the realization of compact and versatile on-chip interconnects between electrical and optical signals. Although light emitting diodes (LEDs) are fundamental building blocks for integrate ...
