Coherence fraction

open access: yesQuantum Information Processing, 2019
The concept of entanglement fraction is generalized to define coherence fraction of a quantum state. Precisely, it quantifies the proximity of a quantum state to maximally coherent state and it can be used as a measure of coherence. Coherence fraction has a connection with $l_1$-norm coherence and provides the criteria of coherence distillability ...

Single-cycle surface plasmon polaritons on a bare metal wire excited by relativistic electrons

open access: yesNature Communications, 2016
Here, the authors demonstrate how ultra-short bunches of relativistic electrons produce coherent transition radiation at the tip of a thin wire. The radiation then propagates as a powerful surface plasmon polariton along the wire, illustrating the ...

Coherent Monoids [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1992
AbstractThis paper is concerned with a new notion of coherency for monoids. A monoid S is right coherent if the first order theory of right S-sets is coherent; this is equivalent to the property that every finitely generated S-subset of every finitely presented right S-set is finitely presented.

Beyond the Features: The Role of Consistency in Impressions of Trust

open access: yesSocial Psychological Bulletin, 2022
To be successful in social life, perceivers need to form impressions of other people's trustworthiness. Current models of this process emphasize the role of specific descriptive content–individual verbal and visual features determining trust impressions.

Time-of-flight electron energy loss spectroscopy using TM110 deflection cavities

open access: yesStructural Dynamics, 2016
We demonstrate the use of two TM110 resonant cavities to generate ultrashort electron pulses and subsequently measure electron energy losses in a time-of-flight type of setup.

Catalytic Coherence [PDF]

open access: yesPhysical Review Letters, 2014
Due to conservation of energy we cannot directly turn a quantum system with a definite energy into a superposition of different energies. However, if we have access to an additional resource in terms of a system with a high degree of coherence, as for standard models of laser light, we can overcome this limitation.

Time-of-flight electron energy loss spectroscopy by longitudinal phase space manipulation with microwave cavities

open access: yesStructural Dynamics, 2018
The possibility to perform high-resolution time-resolved electron energy loss spectroscopy has the potential to impact a broad range of research fields. Resolving small energy losses with ultrashort electron pulses, however, is an enormous challenge due ...

Language-Specific Synchronization of Neural Networks in the Human Brain [PDF]

open access: yesАктуальні питання масової комунікації, 2020
This study examines language-specific characteristics of the electric activity in bilinguals’ brains. The aim of this study was to evaluate language-specific characteristics of functional connectivity related to the perception of verbal information in ...

Coherent emission [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractThe theory of plasma emission and of electron cyclotron maser emission, and their applications to solar radio bursts and to Jupiter's decametric radioation (DAM) and the Earth's auroral kilometric radiation (AKR) are reviewed, emphasizing the early literature and problems that remain unresolved.

Electrical Brain Activity and Its Functional Connectivity in the Physical Execution of Modern Jazz Dance

open access: yesFrontiers in Psychology, 2020
Besides the pure pleasure of watching a dance performance, dance as a whole-body movement is becoming increasingly popular for health-related interventions.
