Abstract Optical gratings can be used to produce more complex potentials than sinusoidal ones. In particular, graphene-like two-dimensional gratings can be produced, in which certain singular points of the Brillouin zone, known as Dirac points, appear. In …

Abstract When a constant force is superimposed on the periodic force created by a grating, an astonishing quantum phenomenon appears: the particles begin to oscillate. Cold atoms confined in optical lattices have enabled us to study this phenomenon in …

Abstract In the early days of electronic music, sounds were recorded and then reproduced in a predefined tempo. This contrasted with the fact that musicians play in constant interaction with each other and with the score, communicating by sight as much as …

Abstract Arshia Cont, a researcher at IRCAM [1] , is developing the Antescofo system for the performance of mixed human/electronic pieces, which amplifies the idea that electronics should be finely directed in real time by humans. After presenting the …

Globalization of risks, global capitalism, standardization of experience, the information society: so many contemporary signs that seem to associate globalization with the need for cosmopolitanism. If the world is establishing itself as a legitimate …
