Order Parameter

Some articles on parameter, order, order parameter, order parameters:

Quantum Phase Transition
... phase transitions, quantum phase transitions can only be accessed by varying a physical parameter - such as magnetic field or pressure - at absolute zero temperature ... Such quantum phase transitions can be second-order phase transition ... Their order is determined by the first discontinuous derivative of a thermodynamic potential ...
Scanning SQUID Microscopy - Applications
... direction of electron momentum k in the superconductor, the magnitude of the order parameter and consequently the superconducting energy gap will be the same ... in the high-temperature cuprate superconductors, the order parameter instead follows the equation Δ(k) = Δ0(cos(kxa)-cos(kya)), meaning that when crossing over any of the directions in ...
Multiferroics - Domains - Properties of Multiferroic Domain Walls
... of transition mediating the transfer of the order parameter from one domain to another ... This may modify the properties of a multiferroic and the coupling of its order parameters ... of the wall The inherent chemical, electronic, or order-parameter inhomogeneity within the walls and the resulting gradient effects ...
Superconductor Insulator Transition - Destruction of Superconductivity
... because the existence of true long-range order is not possible ... along with Berezinski) showed that a different kind of long-range order could exist - topological order - which showed power law correlations (meaning that by measuring the two-point ... can be obtained, but the fluctuations of the order parameter are greatly enhanced, and the transition temperature is suppressed ...
Superconductor Insulator Transition
... is an example of a quantum phase transition, whereupon tuning some parameter in the Hamiltonian, a dramatic change in the behavior of the electrons occurs ... and many studies seek to understand how the order parameter, changes ... Here is the amplitude of the order parameter, and is the phase ...

Famous quotes containing the word order:

    Compassion has no place in the natural order of the world which operates on the basis of necessity. Compassion opposes this order and is therefore best thought of as being in some way supernatural.
    John Berger (b. 1926)
