Design of a frequency-independent optic axis Pancharatnam-based achromatic half-wave plate

Posted by Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kunimoto Komatsu, Hirokazu Ishino, Nobuhiko Katayama, Tomotake Matsumura, Yuki Sakurai | Summary: Pancharatnam-based achromatic half-wave plates (AHWP) achieve high polarization efficiency over a broad waveband. These AWHPs generally contain a property whereby the optic axis is dependent on the electromagnetic frequency of the incident radiation. When the […]

Note: Vibronic coupling in light-harvesting complex II revisited

Posted by klaurent Berkeley

Kavli Affiliate: Graham Fleming | Summary:We discuss our recent theoretical work on vibronic coupling mechanisms in a model energy transfer system in the context of previous 2DEV experiments on a natural light-harvesting system, light-harvesting complex II (LHCII), where vibronic signatures were suggested to be involved in energy transfer. In this comparison, we directly assign the […]

Vibronic coupling in energy transfer dynamics and two-dimensional electronic-vibrational spectra

Posted by klaurent Berkeley

Kavli Affiliate: Graham Fleming | Summary:We introduce a heterodimer model in which multiple mechanisms of vibronic coupling and their impact on energy transfer can be explicitly studied. We consider vibronic coupling that arises through either Franck-Condon activity in which each site in the heterodimer has a local electron-phonon coupling and as Herzberg-Teller activity in which […]

On the origin of observed cosmic ray spectrum below 100 TV

Posted by klaurent Stanford

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: Significant progress in cosmic ray (CR) studies was achieved over the past decade. Particularly important are precise measurements of primary and secondary species in the TV rigidity domain that show a bump in the spectra of […]

Searching for a subpopulation of primordial black holes in LIGO/Virgo gravitational-wave data

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Gabriele Franciolini, Vishal Baibhav, Valerio De Luca, Ken K. Y. Ng, Kaze W. K. Wong | Summary: With several dozen binary black hole events detected by LIGO/Virgo to date and many more expected in the next few years, gravitational-wave astronomy is shifting from individual-event analyses to population […]
