We perform an experimental and theoretical investigation of the rich phase diagram of quantum Hall paramagnetic and ferromagnetic ground states in a double quantum well (DQW) system, and investigate how the structure of this diagram results from the inter-play between spin and pseudospin exchange energies. We use a comparison with a DQW quantum Hall Hartree calculation to identify the nature of...

For binary fluid mixtures of spherical particles in which the two species are sufficiently different in size, the dominant wavelength of oscillations of the pair correlation functions is predicted to change from roughly the diameter of the large species to that of the small species along a sharp crossover line in the phase diagram [C. Grodon et al., J. Chem. Phys. 121, 7869 (2004)]. Using parti...

The phase diagram of strongly interacting matter is explored as a function of temperature and baryon number density. We investigate the possible simultaneous formation of condensates in the conventional quark–anti-quark channel (breaking chiral symmetry) and in a quark–quark channel leading to color superconductivity: the spontaneous breaking of color symmetry via the formation of quark Cooper ...

Consider the standard Poisson process in the first quadrant of the Euclidean plane, and for any point (u, v) of this quadrant take the Young diagram obtained by applying the Robinson-Schensted correspondence to the intersection of the Poisson point configuration with the rectangle with vertices (0, 0), (u, 0), (u, v), (0, v). It is known that the distribution of the random Young diagram thus ob...

Regression models are often used to infer causation from association. For instance, Yule [79] showed – or tried to show – that welfare was a cause of poverty. Path models and structural equation models are later refinements of the technique. Besides Yule, examples to be discussed here include Blau and Duncan [12] on stratification, as well as Gibson [28] on the causes of McCarthyism. Strong ass...

Christopher James Langmead and Sumit Kumar Jha Department of Computer Science, Carnegie Mellon University Abstract. We present a novel approach for predicting protein folding kinetics using techniques from the field of model checking. This represents the first time model checking has been applied to a problem in the field of structural biology. The protein’s energy landscape is encoded symbolic...

Four possible scenarios are considered for a transition from a quark-gluon matter to hadronic matter, and their corresponding correlation signatures are discussed. Four criteria are highlighted for a definitive experimental search for a QCD critical point. An old-new experimental measure, the optical opacity (or its inverse the nuclear attenuation length) is determined, in terms of a combinatio...

We demonstrate that macromolecules in miscible polymer blends may behave as good, Theta, and poor polymeric solvents for each other. We construct a conceptual phase diagram, delineating the range of validity of the random-phase approximation, outside of which polymers contract or expand beyond their unperturbed dimensions, contrary to common assumptions. Remarkably, the correlation length for p...

The UV/IR mixing in the λφ 4 model on a non-commutative (NC) space leads to new predictions in perturbation theory, including Hartree–Fock type approximations. Among them there is a changed phase diagram and an unusual behavior of the correlation functions. In particular this mixing leads to a deformation of the dispersion relation. We present numerical results for these effects in d = 3 with t...
