Photonic Counterparts of Cooper Pairs

open access: yes, 2017
The microscopic theory of superconductivity raised the disruptive idea that electrons couple through the elusive exchange of virtual phonons, overcoming the strong Coulomb repulsion to form Cooper pairs.

Photons, neutrinos and large compact space dimensions [PDF]

open access: yes, 2000
We compute the contribution of Kaluza-Klein graviton exchange to the cross section for photon-neutrino scattering. Unlike the usual situation where the virtual graviton exchange represents a small correction to a leading order electroweak or strong ...

The virtual photon approximation for three-body interatomic Coulombic decay

open access: yes, 2018
Interatomic Coulombic decay (ICD) is a mechanism which allows microscopic objects to rapidly exchange energy. When the two objects are distant, the energy transfer between the donor and acceptor species takes place via the exchange of a virtual photon ...

Exploring the efficacy of pre-service teachers as makers of virtual language/culture learning environments

open access: yesJournal of Virtual Exchange, 2021
Previous literature in the area of computer assisted language learning in Second/Foreign Language (L2/FL) education has highlighted the benefits of using virtual environments for learning the target language and culture (e.g. Blyth, 2018; Lloyd, Rogerson,

On the coupling of two quantum dots through a cavity mode

open access: yes, 2010
The effective coupling of two distant quantum dots through virtual photon exchange in a semiconductor microcavity is studied. The experimental conditions for strong coupling and its manifestation in the spectra of emission are analyzed.Comment: 2 pages ...

Exploring affective barriers in virtual exchange: the telecollaborative foreign language anxiety scale

open access: yesJournal of Virtual Exchange, 2020
The technological revolution of Information and Communication Technology (ICT) has brought about new learning scenarios as well as new professional requirements, such as the development of intercultural and Foreign Language (FL) skills.

Promoting intercultural awareness among European university students via pre-mobility virtual exchanges

open access: yesJournal of Virtual Exchange, 2019
For more than 30 years, the Erasmus programme has given thousands of higher education students throughout Europe the chance to live and study abroad. For many, this sojourn in a foreign country is an extraordinary learning experience which enriches their

Second order coupling between excited atoms and surface polaritons

open access: yes, 2012
Casimir-Polder interactions between an atom and a macroscopic body are typically regarded as due to the exchange of virtual photons. This is strictly true only at zero temperature.

TeV Gravitons and Kaluza-Klein Excitations in $e^+e^-$ and $e^-e^-$ Collisions [PDF]

open access: yes, 2000
We review the capability of $e^+e^-$ and $e^-e^-$ colliders to detect the virtual exchange of Kaluza-Klein towers of gravitons within the large extra dimension scenario of Arkani-Hamed, Dimopoulos and Dvali and in the localized gravity model of Randall ...
