Full nonlinear growing and decaying modes of superhorizon curvature perturbations
Full nonlinear growing decaying modes superhorizon curvature perturbations
2010/12/21
We clarify the behavior of curvature perturbations in a nonlinear theory in case the inflaton tem-porarily stops during inflation. We focus on the evolution of curvature perturbation on superhorizon s...
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaˆıtre-Robertson-Walker type on which they are peaked.
Coincident-Frequency Entangled Photons in a Homogenous Gravitational Field - A Thought Experiment
Coincident-Frequency Entangled Photons Homogenous Gravitational Field - A
2010/12/20
Assuming that the Principle of energy conservation holds for coincident-frequency entangled pho-tons propagating in a homogeneous gravitational field. It is argued that in this physical context,either...
Non-linear corrections to inflationary power spectrum
Non-linear corrections inflationary power spectrum
2010/12/21
We study non-linear contributions to the power spectrum of the curvature perturbation on super-horizon scales, produced during slow-roll inflation driven by a canonical single scalar field. We find th...
Classical GR as a topological theory with linear constraints
Classical GR topological theory linear constraints
2010/12/20
We investigate a formulation of continuum 4d gravity in terms of a constrained topological (BF) theory, in the spirit of the Plebanski formulation, but involving only linear constraints,
Absence of sign problem in the (saddle point approximation of the) nilpotency expansion of QCD at finite chemical potential
nilpotency expansion finite chemical potential
2011/1/13
We have developed a method to derive the (approximate) quark contribution to the fermion free
energy of QCD on a lattice, at finite temperature and chemical potential, with Kogut-Susskind
fermions i...
We investigate potentials between pairs of static-light mesons in Nf = 2 Lattice QCD, in different spin channels.

Nuclear PDFs NLO - status report review of the EPS09 results
2011/1/10
review the current status of the global DGLAP analysis of nuclear parton distribution functions, nPDFs.
Results from a Prototype Chicane-Based Energy Spectrometer for a Linear Collider
Chicane-Based Energy Spectrometer Linear Collider
2010/11/12
The International Linear Collider and other proposed high energy e+ e- machines aim to measure with unprecedented precision Standard Model quantities and new, not yet discovered phenomena. One of the ...
Raman and optical characterization of multilayer turbostratic graphene grown via chemical vapor deposition
Raman optical characterization chemical vapor deposition
2010/11/19
We synthesize large-area graphene via atmospheric-pressure (AP) chemical vapor deposition
(CVD) on copper, and transfer to SiO2 wafers. In contrast to low-pressure (LP) CVD on copper,
optical contra...
Disentanglement and Decoherence without dissipation at non-zero temperatures
Disentanglement Decoherence without dissipation non-zero temperatures
2010/10/20
Decoherence is well understood, in contrast to disentanglement. According to common lore, irre-
versible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show...

2010/10/19
In a 3-wave mixing process occurring in some nonlinear optical medium when a† 1mode interacts
with both a† 2mode and a† 3mode, we theoretically study the squeezing effect generated ...
Non-linear dynamics of double-cavity optical bistability of three-level ladder system
Non-linear dynamics double-cavity optical bistability three-level ladder system
2010/10/21
We present non-linear dynamical features of two-photon double-cavity optical bistability exhibited by a three level ladder system in the mean field limit. The system exhibits a hump like feature in th...

2010/10/20
We develop an enhanced technique for characterizing quantum optical processes based on probing unknown quantum processes only with coherent states. Our method substantially improves the original propo...

Nature's Biochemical Double Slit Molecules React
2010/10/20
Radical-ion-pair reactions were recently shown to represent a rich biophysical laboratory for the application of quantum measurement theory methods and concepts. We here show that radical-ion-pair rea...
