Generalized Inverse Participation Ratio as a Possible Measure of Localization for Interacting Systems
Generalized Inverse Participation Ratio Interacting Systems
2010/11/17
We test the usefulness of a generalized inverse participation ratio (GIPR) as a measure of Anderson localization. The GIPR differs from the usual inverse participation ratio in that it depends on the ...
Marginality of bulk-edge correspondence for single-valley Hamiltonians
Marginality of bulk-edge correspondence single-valley Hamiltonians
2010/11/17
We study the correspondence between the non-trivial topological properties associated with the
individual valleys of gapped bilayer graphene (BLG), as a prototypical multi-valley system, and the gapl...
Population imbalance and pairing in the BCS-BEC crossover of three-component ultracold fermions
Population imbalance three-component ultracold fermions
2010/11/17
We investigate the phase diagram and the BCS-BEC crossover of a homogeneous three-component
ultracold Fermi gas with a U(3) invariant attractive interaction. We show that the system at
sufficiently ...
Sphere packing problems have a rich history in both mathematics and physics; yet,
relatively few analytical analyses of sphere packings exist, and answers to seemingly simple ques-tions are unknown. ...
We introduce a variant of the replica trick within the nonlinear sigma model that allows calculating the distribution function of the persistent current. In the diffusive regime, a Gaussian distributi...
Watch This Space: Observing Merging White Dwarfs
binary stars white dwarfs stellar evolution supernovae
2010/12/21
The Laser Interferometer Space Antenna (LISA) will open the low-frequency (0.1-100 mHz) part of the gravitational wave spectrum to direct observation. Of order 3600 galactic close binary white dwarfs ...
Staggered chiral perturbation theory in the two-flavor case and SU(2) analysis of the MILC data
Staggered chiral perturbation theory two-flavor case SU(2) analysis of the MILC data
2011/1/13
In the light pseudoscalar sector, we study rooted staggered chiral perturbation theory in the
two-flavor case. The pion mass and decay constant are calculated through NLO for a partiallyquenched theo...
Saturation and Scaling of Multiplicity, Mean p_T and p_T Distributions from 200 GeV < sqrt{s} < 7 TeV - Addendum
Saturation and Scaling of Multiplicity Mean p_T and p_T Distributions
2011/1/7
In the previous paper we have argued that the LHC data on multiplicity,average transverse momentum, and charged particle transverse momentum distributions are well described with minimal modeling in t...
Absence of scaling in transport through two-dimensional nanoparticle arrays
Absence of scaling two-dimensional nanoparticle arrays
2010/11/17
We analyze the transport in disordered two-dimensional nanoparticle arrays. We show that the
commonly used scaling hypothesis to fit the I-V curves does not describe the electronic transport in these...
Statistical Properties of Cosmological Billiards
Statistical Properties Cosmological Billiards
2010/12/20
Belinski, Khalatnikov and Lifshitz (BKL) pioneered the study of the statistical properties of the never-ending oscillatory behavior (among successive Kasner epochs) of the geometry near a space-like s...
We consider an analytic way to make the interacting N-body problem tractable by using harmonic oscillators in place of the relevant two-body interactions.The two-body terms of the N-body Hamiltonian a...
Maximal Analytic Extension and Hidden Symmetries of the Dipole Black Ring
Maximal Analytic Extension Hidden Symmetries Dipole Black Ring
2010/12/21
We construct analytic extensions across the Killing horizons of non-extremal and extremal
dipole black rings in Einstein-Maxwell’s theory using different methods. We show that these
extensions are n...
Determining source cumulants in femtoscopy with Gram-Charlier and Edgeworth series
femtoscopy Edgeworth series correlations interferometry
2011/1/6
Lowest-order cumulants provide important information on the shape of the emission source in femtoscopy. For the simple case of noninteracting identical particles, we show how the fourth-order source c...
First-principles predictions of low-energy phases of multiferroic BiFeO3
First-principles predictions multiferroic BiFeO3
2010/11/17
We used rst-principles methods to perform a systematic search for potentially-stable phases of multiferroic BiFeO3. We considered a simulation cell compatible with the atomic distortions that are mos...
Non-equilibrium physics at a holographic chiral phase transition
Non-equilibrium physics holographic chiral phase transition
2011/1/7
The D3/D7 system holographically describes an N=2 gauge theory which in the presence of a magnetic field. At finite temperature it displays a first order phase transiion.We study out of equilibrium dy...
