PIRSA:12100124  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Matter-wave clocks
Speaker(s): Holger Mueller
Abstract:
Date: 22/10/2012 - 9:15 am

PIRSA:12100127  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Improved test of the Equivalence Principle as a probe of quantum gravity
Abstract: Current approaches to the problems of dark energy and unification generically predict the existence of new fields (quintessence dilatons etc.) that will in principle couple with different strengths to different standard-model fields. These different coupling strengths will cause test materials of di... read more

PIRSA:12100084  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Lorentz Invariance Violation searches with HESS
Speaker(s): Julien Bolmont
Abstract: The high flux and variability of the blazar PKS 2155-304 as observed by H.E.S.S. during the night of 28 July 2006 allowed a very high precision search for Quantum Gravity-induced energy-dependent time lags. In this talk, I will review the results published by the H.E.S.S. collaboration on this topic... read more

PIRSA:12100085  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Photons and Quantum Gravity in Astrophysics
Abstract: Asymptotically safe inflation and CMB polarizationThe presence of complex critical exponents in the scaling behavior of the Newton constant and Cosmological  constant has dramatic consequences at the inflation scale. In particular an infinite number of unstable de-Sitter vacua emerges from ... read more

PIRSA:12100089  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
The highest-energy particles of the Universe as viewed by the Pierre Auger Observatory
Speaker(s): Markus Risse
Abstract: One century after the seminal balloon flights of Victor Hess, the Pierre Auger Observatory aims at unveiling some of the mysteries of the highest-energy cosmic rays: what are their sources? Is there an end to the spectrum? What kind of particles are they? Are there signatures of new physics or of a ... read more

PIRSA:12100090  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Quantum Gravity Effects in the (Early and Late) Universe
Abstract: Quantum Gravity at the origin of seeds of cosmic structure?This meeting shows a our impatience for uncovering at long last any signal of unknown physics that might have a quantum gravitational origin. I will argue that the transition from a homogenous and isotropic state characterizing the mid-earl... read more

Searching for Quantum Gravity with the IceCube Neutrino Observatory
Speaker(s): John Kelley
Abstract: The IceCube Neutrino Observatory is a cubic-kilometer-scale neutrino detector built into the ice sheet at the geographic South Pole.  Completed in December 2010, the detector consists of an array of photomultiplier tubes deployed along 86 cables ("strings") at depths of 1450 to 2450 m, as w... read more

PIRSA:12100094  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Quantum Gravity Effects in Black Holes and Gravitational Waves
Abstract: Quantum-gravity effects as noise for gravity-wave detectorsI discuss a mechanism that can allow Planck scale effects to manifest themselves as a source of lof-frequency noise for interferometers.  The mechanism requires a discrete formulation of dynamics at the Planck scale._______________... read more

PIRSA:12100126  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Cosmological Constant
Abstract: Dark Matter and Dark Energy as a Possible Manifestation of a Fundamental ScaleIf we take the idea of the Planck length as a fundamental (minimum) scale and if additionally we impose the Cosmological Constant ($Lambda$) as and infrared (IR) cut-off parameter. Then it is possible to demonstrate that D... read more
