Packaging stiff polymers in small containers: A molecular dynamics study

2016-09-28T10:00:00-04:00

Author(s): D. C. Rapaport
The question of how stiff polymers are able to pack into small containers is particularly relevant to the study of DNA packaging in viruses. A reduced version of the problem based on coarse-grained representations of the main components of the system—the DNA polymer and the spherical viral capsid—ha…

Author(s): Gernot Schaller, Giulio Giuseppe Giusteri, and Giuseppe Luca Celardo
We investigate heat transport between two thermal reservoirs that are coupled via a large spin composed of N identical two-level systems. One coupling implements the dissipative Dicke superradiance. The other coupling is locally of the pure-dephasing type and requires to go beyond the standard weak-…
