Quantum time correlation functions are often the principal objects of interest in experimental investigations of the dynamics of quantum systems. For instance, transport properties, such as diffusion and reaction rate coefficients, can be obtained by integrating these functions. The evaluation of such correlation functions entails sampling from quantum equilibrium density operators and quantum ...

INTRODUCTION Kendon distinguishes between two different types of gestures: " 'Pragmatic' gestures that indicate type of speech act or aspects of discourse structure and 'substantive' gestures that express utterance content " (1995:247). He further defines 'pragmatic gestures' as playing " modal, performative and parsing functions " as well as " interpersonal functions " (Kendon, 2004:159). A ge...
