Microwave Electrometry with Multi-Photon Coherence in Rydberg Atoms

open access: yesSensors, 2023
A scheme for the measurement of a microwave (MW) electric field is proposed via multi-photon coherence in Rydberg atoms. It is based on the three-photon electromagnetically induced absorption (TPEIA) spectrum. In this process, the multi-photon produces a

Phasing the Mirror Segments of the Keck Telescopes: The Broadband Phasing Algorithm [PDF]

open access: yes, 1998
To achieve its full diffraction limit in the infrared, the primary mirror of the Keck telescope (now telescopes) must be properly phased: The steps or piston errors between the individual mirror segments must be reduced to less than 100 nm. We accomplish

Suppression of decoherence in a graphene monolayer ring [PDF]

open access: yes, 2014
The influence of high magnetic fields on coherent transport is investigated. A monolayer graphene quantum ring is fabricated and the Aharonov-Bohm effect is observed. For increased magnitude of the magnetic field higher harmonics appear.

Projectile Coherence Effects in Twisted Electron Ionization of Helium

open access: yesAtoms, 2023
Over the last decade, it has become clear that for heavy ion projectiles, the projectile’s transverse coherence length must be considered in theoretical models.

Coherence between subjective experience and physiology in emotion: Individual differences and implications for well-being. [PDF]

open access: yes, 2020
Emotion theorists have characterized emotions as involving coherent responding across various emotion response systems (e.g., covariation of subjective experience and physiology). Greater response system coherence has been theorized to promote well-being,

Reducing the impact of radioactivity on quantum circuits in a deep-underground facility [PDF]

open access: yes, 2020
As quantum coherence times of superconducting circuits have increased from nanoseconds to hundreds of microseconds, they are currently one of the leading platforms for quantum information processing.

Quantum biology on the edge of quantum chaos [PDF]

open access: yes, 2012
We give a new explanation for why some biological systems can stay quantum coherent for long times at room temperatures, one of the fundamental puzzles of quantum biology.
