 We begin with the sub-Laplacian on the Heisenberg group. The 
  
 twisted Laplacian is then introduced by taking the inverse Fourier 
  
 transform of the sub-Laplacian with respect to the center of the 
  
 Heisenberg group. After a recapitulation of the spectral theory of the 
  
 twisted Laplacian in terms of the Wigner transform, the spectral theory 
  
 and number theory of the twisted bi-Laplacian obtained by Todor 
  
 Gramchev, Stevan Pilipovic, Luigi Rodino and me are reported. We end 
  
 the talk with some new results on the trace of the heat semigroup and 
  
 the Dixmier trace of the inverse of the twisted bi-Laplacian based on a 
  
 connection with the Riemann zeta function.
