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

Kavli Affiliate: Graham R. Fleming | First 5 Authors: Eric A. Arsenault, Addison J. Schile, David T. Limmer, Graham R. 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 […]

On the origin of observed cosmic ray spectrum below 100 TV

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 […]

Supersymmetry and multicriticality in a ladder of constrained fermions

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, Jiří Minář, Kareljan Schoutens, , | Summary: Supersymmetric lattice models of constrained fermions are known to feature exotic phenomena such as superfrustration, with an extensive degeneracy of ground states, the nature of which is however generally unknown. Here we address this issue by considering a […]

Quantum networks based on color centers in diamond

Kavli Affiliate: Ronald Hanson | First 5 Authors: Maximilian Ruf, Noel H. Wan, Hyeongrak Choi, Dirk Englund, Ronald Hanson | Summary: With the ability to transfer and process quantum information, large-scale quantum networks will enable a suite of fundamentally new applications, from quantum communications to distributed sensing, metrology, and computing. This perspective reviews requirements for […]

Reinforcement learning of rare diffusive dynamics

Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Dominic C. Rose, Juan P. Garrahan, David T. Limmer, | Summary: We present a method to probe rare molecular dynamics trajectories directly using reinforcement learning. We consider trajectories that are conditioned to transition between regions of configuration space in finite time, like those relevant […]

CMB Mode Coupling with Isotropic Polarization Rotation

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We provide a new analysis technique to measure the effect of the isotropic polarization rotation, induced by e.g. the isotropic cosmic birefringence from axion-like particles and a miscalibration of CMB polarization angle, via mode coupling in the cosmic microwave background […]

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

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 […]

The Sloan Digital Sky Survey Reverberation Mapping Project: UV-Optical Accretion Disk Measurements with Hubble Space Telescope

Kavli Affiliate: Luis C. Ho | First 5 Authors: Y. Homayouni, Megan R. Sturm, Jonathan R. Trump, Keith Horne, C. J. Grier | Summary: We present accretion-disk structure measurements from UV-optical reverberation mapping observations of a sample of eight quasars at 0.24<z<0.85. Ultraviolet photometry comes from two cycles of Hubble Space Telescope monitoring, accompanied by […]
