Partial-Wave Analyses as a Method
for Studying Baryon Spectroscopy
Abstract: A single polymer chain can undergo a series of conformational transitions analogous to the phase transitions exhibited by bulk materials. Our recent work studies such single chain phase transitions using the Wang-Landau (WL) algorithm, a Monte Carlo simulation technique providing a direct computation of the density of states (and thus the partition function) of a many-body system. The partition function encodes all thermodynamic information about a system, and thus, its construction allows for an efficient determination of phase behavior. Here we describe the application of the WL approach to a number of coarse-grained model polymers. We study single chain folding and adsorption transitions in these systems using canonical and micro-canonical thermodynamics and through analysis of partition function zeros. In the latter case, the distribution of these zeros in the complex plane provides distinctive signatures for different transitions. With increasing chain length these zeros pinch down towards the positive real axis, dividing this axis into distinct regions or phases, in accord with the theory of Yang and Lee. Using finite size scaling theory for the leading partition function zeros we can locate phase transition in the thermodynamic limit and determine critical exponents.
The Speaker: Mark Manley earned a B.S. degree in physics from Northeast Louisiana University (now the University of Louisiana at Monroe) in 1975. Afterwards, he began graduate school at the University of Wyoming. His Ph.D. research in medium-energy nuclear physics was performed at Los Alamos National Laboratory, where he resided from 1978 to 1981. After earning his Ph.D. in 1981, he had postdoctoral appointments at Virginia Tech (1981 to 1984) and Lawrence Livermore National Laboratory (1984 to 1986). In 1986, he started his career in the Department of Physics at Kent State University. He has been a full professor there since 1997. For the past 10 years, his experimental research has been performed in Mainz, Germany as part of the Crystal Ball and A2 Collaborations. He currently has about 120 publications in refereed physics journals and has presented over 30 invited talks at scientific meetings worldwide.
