Abstract

Studying the order of the chiral transition for Nf = 2 is of fundamental importance to understand the mechanism of color confinement. We present results of a numerical investigation on the order of the transition by use of a novel strategy in finite size scaling analysis. The specific heat and a number of susceptibilities are compared with the possible critical behaviours. A second order transition in the O(4) and O(2) universality classes are excluded. Substantial evidence emerges for a first order transition. Results are in agreement with those found by studying the scaling properties of a disorder parameter related to the dual superconductivity mechanism of color confinement.

Ionic Conductivity of Block Copolymer Electrolytes in the Vicinity of Order−Disorder and Order−Order Transitions

Wanakule, Nisita S. ; Panday, Ashoutosh ; Mullin, Scott A. ; ... - Macromolecules

Order-order and order-disorder phase transitions in mixtures of poly(styrene-block-ethylene oxide) (SEO) copolymers and lithium bis(trifluoromethylsulfonimide) (LiTFSI), a common lithium salt used in polymer electrolytes, were studied using a combination of small-angle X-ray scattering (SAXS), birefringence, and ac impedance spectroscopy. The SEO/LiTFSI mixtures exhibit lamellar, hexagonally packed cylinders, and gyroid microphases. The molecular weight of the blocks and the salt concentration was adjusted to obtain order-order and order-disorder transition temperatures within the available experimental window. The ionic conductivities of the mixtures, normalized by the ionic conductivity of a 20 kg/mol homopolymer PEO sample at the salt concentration and temperature of interest,more »« less

W/100/ clean surface phase transition studied by core-level-shift spectroscopy: Order-order or order-disorder transition

Jupille, J. ; Purcell, K.G. ; King, D.A. - Phys. Rev. B: Condens. Matter; (United States)

W4f/sub 7/2/ core-level spectra are recorded from the high- and low-temperature phases on a ''flat'' W(100) crystal. In the high-temperature phase, the core-level binding energy associated with surface atoms is 370 +- 10 meV lower than that from the bulk atoms. This binding energy is found to be shifted by 15 +- 5 meV in the low-temperature phase. The magnitude of this shift and an excess broadening observed in the surface peak from the high-temperature phase give evidence for disorder in this phase, in which the surface atoms have similar local coordination to those of the low-temperature phase. The surfacemore »« less

Growth and characterization of GaInP unicompositional disorder-order-disorder quantum wells

Schneider, R.P. Jr. ; Jones, E.D. ; Follstaedt, D.M. - Applied Physics Letters; (United States)

Metalorganic vapor phase epitaxy (MOVPE) is used to grow unicompositional quantum-well (QW) structures, in which the QW and barrier layers are composed of ordered and disordered GaInP, respectively. Transmission electron dark-field micrographs reveal abrupt interfaces between highly ordered QWs and disordered barriers, with no evidence of defect formation. Low-temperature photoluminescence from the structures exhibits relatively broad emission peaks, with emission energy increasing with decreasing QW thickness. The dependence of emission energy on well thickness can be described by a finite square well model only when a type-II band alignment is taken for the heterostructure, in which the conduction band edgemore »« less

Order-Disorder Transition in One-Dimensional System with Disorder in Composition

Morozov, V.F. ; Badasyan, A.V. ; Mamasakhlisov, E.Sh. ; ... - Physics of Atomic Nuclei

The influence of structural inhomogeneity onto order-disorder transitions in 1D systems is considered in the scope of the Potts-like model with many-particle interactions. The helix-coil transition in DNAs, heterogeneous by hydrogen bonding energy, is considered as an example. The microcanonical method is employed to evaluate the free energy. The secular equation for the heteropolymer is constructed. Both the melting temperature and interval of DNA melting are obtained. In the limit of small difference between inverse melting temperatures of poly(A-T) and poly(G-C), the coincidence with classical results is obtained.
