We are interested in the interplay between cosmology and quantum theory to probe some phenomena predicted within various quantum gravity proposals. Recently we formed a collaboration with Prof. Peter Krueger (University of Nottinghan) to persue the idea of utilizing parametrically excited Bose-Einstein condensates to mimic cosmological particle production in the laboratory. 

 

The project is a joint-collaboration between the School of Mathematics and the School of Physics & Astronomy at the University of Nottingham:
  Peter Krueger (School of Physics & Astronomy, University of Nottingham)

  Fedja Orucevic (School of Physics & Astronomy, University of Nottingham)

  Thomas Barrett (School of Physics & Astronomy, University of Nottingham)

  Silke Weinfurtner (School of Mathematics, University of Nottingham) 
  Andreas Finke (School of Physics & Astronomy, University of Nottingham)

 

External collaborators:

  Piyush Jain (University of Alberta, Edminton, Canada)
