Aichinger, M.; Chin, Siu A.; Krotscheck, E.; Rasanen, E. (American Physical Society, 2006)We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field and/or the electron number are/is increased, ...

He, Hong-Wei (Texas A&M University. Libraries, 1992)In this dissertation, we use the parquet summation for the two-body vertex as the framework for a perturbation theory of finite-temperature homogeneous boson systems. Our present formalism is a first step toward a full ...

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 ...
