Practical constraints on estimation of source extent with MEG beamformers
Abstract We aimed to determine practical constraints on the estimation of the spatial extent of neuronal activation using MEG beamformers. Correct estimation of spatial extent is a pre-requisite for accurate models of electrical activity, allows one ...

Quantum field, interference, and entanglement effects in nonlinear optical spectroscopy
Abstract Experimental observables in quantum systems may be represented by Liouville space pathways which describe the evolving density matrix. The pathways of coupled degrees of freedom may become entangled leading to interesting interference...

Nuclear and Crystal State Aspects of Overlapping Holographic Phase Patterns
Abstract Holographic aspects of 2D Fresnel type memory patterns with 3D couplings and mutual diffractions are considered. Encoding topological charges and spin, the nonlinear interaction potentials are assigned to a shared holographic memory phase...

Low-energy moments of heavy quark current correlators at four loops
Abstract We describe several techniques for the calculation of multi-loop integrals and their application to heavy quark current correlators. As new results, we present the four-loop correction to the second and third physical moments in the...

On Kolmogorov wave turbulence in QCD
Abstract We investigate Kolmogorov wave turbulence in QCD or, in other words, we calculate the spectrum of gluons as a function of time, f k ...

Geometric Lagrangians for massive higher-spin fields
Abstract Lagrangians for massive, unconstrained, higher-spin bosons and fermions are proposed. The idea is to modify the geometric, gauge invariant Lagrangians describing the corresponding massless theories by the addition of suitable quadratic...

Positronium-like states from supergravity
Abstract We study semi-classical rotating open strings ending on a probe Dp-brane close to a stack of extremal, non-extremal Dp-branes and Dp-branes with B-fields. These states may be interpreted as positronium-like bound states of spinning W-bosons ...

Marginally deformed rolling tachyon around the tachyon vacuum in open string field theory
Abstract We investigate the string field theory around the tachyon vacuum. A pure gauge form of the solution is constructed at the tachyon vacuum. For a special choice of the gauge function for the pure gauge form, marginal deformation from the...

Y-junction of superconducting Josephson chains
Abstract We show that, for pertinent values of the fabrication and control parameters, an attractive finite coupling fixed point emerges in the phase diagram of a Y-junction of superconducting Josephson chains. The new fixed point arises only when...

Constraining superWIMPy and warm subhalos with future submillilensing
Abstract We propose to observe QSO-galaxy strong lens systems to give a new constraint on the damping scale of the initial fluctuations. We find that the future observation of submilliarc scale astrometric shifts of the multiple lensed images of...

Reparameterization invariance of NRQED self-energy corrections and improved theory for excited D states in hydrogenlike systems
Abstract Canonically, the quantum electrodynamic radiative corrections in bound systems have been evaluated in photon energy regularization, i.e., using a noncovariant overlapping parameter that separates the high-energy relativistic scales of the...

Classical and quantum dynamics of a perfect fluid scalar-metric cosmology
Abstract We study the classical and quantum models of a Friedmann–Robertson–Walker (FRW) cosmology, coupled to a perfect fluid, in the context of the scalar-metric gravity. Using the Schutz' representation for the perfect fluid, we show that, under...
