ONCE UPON A TIME IN KAMCHATKA: THE EXTRAORDINARY SEARCH FOR NATURAL QUASICRYSTALS

March 06, 2013

PIRSA:13030076

A quasicrystal is an exotic state of matter with symmetries once thought to be impossible for matter. The concept was first introduced and the first examples were synthesized in the laboratory thirty years ago, but could Nature have beaten us to the punch? This talk will describe the search for the first natural quasicrystal, An adventure to the ends of the Earth and beyond and one of the wildest scientific stories you are ever likely to hear.
Rethinking Cosmology

PIRSA:13030079

Cosmology

This talk will begin by discussing one by one the various reasons why cosmologists today consider the big bang inflationary cosmology to be the leading, if not proven, theory of the universe and then explaining why each of these reasons is flawed. This leads naturally to the question: what is the alternative? Understanding the flaws helps point the way.

Non-perturbative problems in gauge theories: N=2 quiver QCD

Vasily Pestun Institute for Advanced Study (IAS)

March 06, 2013

PIRSA:13030103

Quantum Fields and Strings

Non-perturbative effects are responsible for the essential dynamical features of the four-dimensional gauge theories such as QCD. The N=2 supersymmetric four-dimensional theories are an interesting class of models in which non-perturbative computations can be carried out with arbitrary precision using localization of the path integrals. I will explain the new exact non-perturbative results and the relation to classical and quantum integrable systems for a large class of N=2 supersymmetric QCD.

Thermodynamical Property of Entanglement Entropy for Excited States and Holographic Local Quench

PIRSA:13030081

Quantum Fields and Strings

In this talk, we will describe our recent work. Recently, we focus on the thermodynamical property and time dependence of entanglement entropy. Using holography, we found that the entanglement entropy for a very small subsystem obeys a property which is analogous to the first law of thermodynamics when we excite the system. In relativistic setups, its effective temperature is proportional to the inverse of the subsystem size. This provides a universal relationship between the energy and the amount of quantum information. Moreover, we will propose a new holographic model of local quench and describe some results which we got by using this model. This talk is based on arXiv:1212.1164 [hep-th] and arXiv:1302.5703 [hep-th].
The correlator of two vector and one axial current in QCD

Particle Physics

It is known that the correlator of one axial and two vector currents, that receives leading contributions through one-loop fermion triangle diagrams, is not modified by QCD radiative corrections at two loops. It was suggested that this non-renormalization of the VVA correlator persists in higher orders in perturbative QCD as well. To check this assertion, I compute the three-loop QCD corrections to the VAA-correlator using the technique of asymptotic expansions. I find that these corrections do not vanish and that they are proportional to the QCD beta-function. I will also review some properties of the VVA correlator that were discovered in recent years.
