Effects of hydrodynamic interactions (HI), incorporated via the Rotne-Prager-Yamakawa tensor, are found to play a key role in assisting the collapse, which significantly speeds up the process. At large quench depth, the polymer molecule typically gets trapped in long-lived metastable (glassy) states, before going to the final globular state. Visual inspection indicates that the kinetic pathways of the coil-globule transition are independent of the strength of HI; however, they are significantly different for shallow and deep quenches. Moreover, the results seem to indicate that at large quench depth the collapse time depends on the strength of HI in a non-monotonous way.
