Literary linguistics: Open Access research in English language

Strathprints makes available Open Access scholarly outputs by English Studies at Strathclyde. Particular research specialisms include literary linguistics, the study of literary texts using techniques drawn from linguistics and cognitive science.

The team also demonstrates research expertise in Renaissance studies, researching Renaissance literature, the history of ideas and language and cultural history. English hosts the Centre for Literature, Culture & Place which explores literature and its relationships with geography, space, landscape, travel, architecture, and the environment.

Abstract

Scientists are now exploiting orbital angular momentum in various experiments. Orbital angular momentum can arise if phase fronts, such as wave crests, become twisted around the direction of light propagation. Since the phenomenon was confirmed in 1992, researchers have investigated it in many experiments, initially with classical techniques but increasingly on the quantum level. Areas where orbital angular momentum can be used include in optical tweezers to rotate small particles; it can also be transferred from light to ultracold molecules, and it can be used as a model for applications in quantum cryptography.
