Sommario/riassunto |
|
This thesis reports the remarkable discovery that, by arranging the dipoles in an ordered array with particular spacings, it is possible to greatly enhance the cross-section and achieve a strong light-matter coupling (>98% of the incident light). It also discusses the broad background to cooperative behaviour in atomic ensembles, and analyses in detail effects in one- and two-dimensional atomic arrays. In general, when light interacts with matter it excites electric dipoles and |

since the nineteenth century it has been known that if the amplitude of these induced dipoles is sufficiently large, and their distance apart is on the scale of the wavelength of the light, then their mutual interaction significantly modifies the light–matter interaction. However, it was not known how to exploit this effect to modify the light–matter interaction in a desirable way, for example in order to enhance the optical cross-section. |

Sommario/riassunto |
|
Los últimos treinta años de la antropología médica del sur de Europa han permitido que esta evolucione de un abordaje básicamente descriptivo y enumerativo de otras formas de enfermar, otras visiones del curar y otros espacios de sanar, a una mirada crítica y atenta a la pluralidad de recursos que se encuentran a nuestro alrededor, así como a sus implicaciones técnicas, ideológicas y normalizadoras. Se da cabida aquí a debates metodológicos clásicos, reavivados explícitamente por la lectura actual tanto de la salud internacional como de la diversidad de usuarios, así como a la explosión/implosión del modelo médico hegemónico. Otras contribuciones versan sobre el sentido de la subdisciplina y de una etnografía autorreferencial y crítica. Por último, se apuntan las carencias del canon asentado, indicando rupturas y emergencias transgresoras en relación con los dispositivos institucionales y las manifestaciones crecientes de la |
