Hexatic-Herringbone Coupling at the Hexatic Transition in Smectic Liquid Crystals: 4- Renormalization Group Calculations Revisited
Mohammad Kohandel, Michel J. P. Gingras, Josh P. Kemp
Simple symmetry considerations would suggest that the transition from the smectic-A phase to the long-range bond orientationally ordered hexatic smectic-B phase should belong to th…
Folding dynamics of the helical structures in a minimal model
Josh P. Kemp, Jeff Z. Y. Chen
The folding of a polypeptide is an example of the cooperative effects of the amino-acid residues. Of recent interest is how a secondary structure, such as a helix, spontaneously fo…
Is there a universality of the helix-coil transition in protein models?
Josh P. Kemp, Ulrich H. E. Hansmann, Zheng Y. Chen
The similarity in the thermodynamic properties of two completely different theoretical models for the helix-coil transition is examined critically. The first model is an all-atomic…
Semi-Analytical Calculation of the Rouse Dynamics of Randomly Branched Polymers
Josh P. Kemp, Zheng Yu Chen
We present a semi-analytical approach to the determination of the dynamic properties of randomly branched polymers under the Rouse approximation. The principle procedure is based o…
Formation of helical states in wormlike polymer chains
Josh P. Kemp, Zheng Yu Chen
We propose a potential for wormlike polymer chains which can be used to model the low-temperature conformational structures. We successfully reproduced helix ground states up to 6.…
