Spin wavepackets in the Kagome ferromagnet Fe$_3$Sn$_2$: propagation and precursors

Kavli Affiliate: Joel Moore | First 5 Authors: Changmin Lee, Yue Sun, Linda Ye, Sumedh Rathi, Kevin Wang | Summary: The propagation of spin waves in magnetically ordered systems has emerged as a potential means to shuttle quantum information over large distances. Conventionally, the arrival time of a spin wavepacket at a distance, $d$, is […]

Effects of the interplay between fermionic interactions and disorders in the nodal-line superconductors

Kavli Affiliate: Jing Wang | First 5 Authors: Wen-Hao Bian, Xiao-Zhuo Chu, Jing Wang, , | Summary: We study the interplay between fermion-fermion interactions and disorder scatterings beneath the superconducting dome of noncentrosymmetric nodal-line superconductors. With the application of renormalization group, several interesting low-energy behaviors are extracted from the coupled equations of all interaction parameters. […]

Controlled crossed Andreev reflection and elastic co-tunneling mediated by Andreev bound states

Kavli Affiliate: Michael Wimmer | First 5 Authors: Alberto Bordin, Guanzhong Wang, Chun-Xiao Liu, Sebastiaan L. D. ten Haaf, Grzegorz P. Mazur | Summary: A short superconducting segment can couple attached quantum dots via elastic co-tunneling (ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host Majorana bound states provided that the ratio […]

A hybrid quantum photonic interface for $^{171}$Yb solid-state qubits

Kavli Affiliate: Andrei Faraon | First 5 Authors: Chun-Ju Wu, Daniel Riedel, Andrei Ruskuc, Ding Zhong, Hyounghan Kwon | Summary: $^{171}$Yb$^{3+}$ in YVO$_4$ is a promising candidate for building quantum networks with good optical addressability, excellent spin properties and a secondary nuclear-spin quantum register. However, the associated long optical lifetime necessitates coupling to optical resonators […]

Microbial symbionts are shared between ants and their associated beetles

Kavli Affiliate: Daniel Kronauer | Authors: Catalina Valdivia, Justin A. Newton, Sean O’Donnell, Christoph von Beeren, Daniel J. C Kronauer, Jacob A Russell and Piotr Lukasik | Summary: Abstract The transmission of microbial symbionts across individuals and generations can be critical for animal development and survival. Likewise, the transmission of microbes across closely interacting species […]

Unclearing Microscopy

Kavli Affiliate: Joerg Bewersdorf | Authors: Ons M’Saad, Michael Shribak and Joerg Bewersdorf | Summary: Abstract The spatial resolution and contrast sensitivity of the human eye is limited, restricting our ability to directly see subcellular structures. We report a new principle for unaided eye cellular visualization in a method we call Unclearing Microscopy. By expanding […]

Optical Refrigeration for an Optomechanical Amplifier

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Samuel Schulz, Yehonathan Drori, Christopher Wipf, Rana X Adhikari, | Summary: We explore the viability of using optical refrigeration as a low-vibration cooling method for a phase-sensitive optomechanical amplifier proposed to improve the sensitivity of future gravitational wave detectors. We find that with moderate improvements on […]

A New Component from the Quiet Sun: Synchrotron Radiation from Galactic Cosmic-Ray Electrons

Kavli Affiliate: Vahe Petrosian | First 5 Authors: , , , , | Summary: The quiet Sun, i.e. in its non-flaring state or non-flaring regions, emits thermal radiation from radio to ultraviolet. The quiet Sun produces also non-thermal radiation observed in gamma rays due to interactions of Galactic Cosmic Rays (GCR) with the solar gas […]

Transport of Cosmic ray electrons from 1 AU to the Sun

Kavli Affiliate: Vahe Petrosian | Summary:Gamma rays are produced by cosmic ray (CR) protons interacting with the particles at solar photosphere and by cosmic ray electrons and positrons (CRes) via inverse Compton scattering of solar photons. The former come from the solar disk while the latter extend beyond the disk. Evaluation of these emissions requires […]
