Discrete quantum trajectories and Brownian motion experiments
Janet Anders
Department of Physics, University of Exeter, UK

Abstract: In the first part of the talk I will review how work and  
heat are characterised in classical statistical processes. I will then  
explain the issues involved in extending these concepts to the quantum  
regime and describe our approach of discrete quantum trajectories [1].  
In the second part of the talk I will report on our theory-experiment  
research with heated optically trapped nanospheres in a dilute gas  
[2]. By developing a new theoretical model that captures the  
non-equilibrium situation of the particles we were able to measure the  
surface temperature of the trapped spheres and observe temperature  
gradients on the nanoscale.
