Structure, rotational dynamics, and superfluidity of small OCS-doped He clusters
Saverio Moroni, Antonio Sarsa, Stefano Fantoni +2
The structural and dynamical properties of OCS molecules solvated in Helium clusters are studied using reptation quantum Monte Carlo, for cluster sizes n=3-20 He atoms. Computer si…

Number--conserving model for boson pairing
S. Fantoni, T. M. Nguyen, A. Sarsa +1
An independent pair ansatz is developed for the many body wavefunction of dilute Bose systems. The pair correlation is optimized by minimizing the expectation value of the full ham…
