    • Short-time-evolved wave functions for solving quantum many-body problems 
      Ciftja, O.; Chin, Siu A. (American Physical Society, 2003)
      The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In many cases, since the convergence ...
    • Structure and Collective Excitations of He-4 Clusters 
      Chin, Siu A.; KROTSCHECK, E. (American Physical Society, 1992)
      We compute zero-temperature ground-state energies, one- and two-body densities, collective-excitation spectra, transition densities, and static and dynamic structure functions of He-4 clusters up to a cluster size of N = ...
    • Theory of first-order layering transitions in thin helium films 
      Saslow, WM; Agnolet, Glenn; Campbell, CE; Clements, BE; Krotscheck, E. (American Physical Society, 1996)
      Thin liquid He-4 films on graphite show evidence of layered growth with increasing number density via a succession of first-order phase transitions. These so-called ''layering transitions'' separate uniformly covering ...
