Ben Gurion UniversityOrganizer Department of Chemical and Biological PhysicsContact Abstract Show full text abstract about When matter is placed in the confined field of electromagnet...» When matter is placed in the confined field of electromagnetic radiation, it can lead to modified and even new properties. This is of great interest from both the fundamental point of view as well as for many radiation engineering applications. For instance, the field confinement can lead to effects such as extraordinary optical transmission, enhanced absorption and emission of light, high-resolution spectroscopy and imaging. Under certain conditions, the light-matter interaction can become so strong that it enters the so-called strong coupling regime where new hybrid light-matter states are formed, offering a vast potential for chemistry and biology that has hardly been explored.
In this talk, an introduction to strong coupling of optically-active substances with confined optical modes will be presented. Strong coupling of molecular vibrational transitions in the infra-red region will be particularly elaborated with new prospects to modify molecular and structural processes. The hybridization of molecular vibrational transitions by the confined electromagnetic field of an optical cavity, leading to the formation of vibro-polariton states, should have direct consequences on the properties of the material. Probing nonlinear properties of the coupled system to understand the character of the hybrid states will be addressed. In addition, new directions for exploiting strong light-matter interactions for (bio) molecular spectroscopy and other practical applications will be discussed.

Among applications are random matrix models, superfluid flow, quantum Hall effect, etc. Important properties of the model are revealed if the surface is curved. Recently a method was developed to generate the expansion in gradients of curvature of the surface.

Measurement of the charged-pion polarizability at CERN COMPASS
More information Time 15:00 - 15:45Location Tel Aviv University campusLecturer Murray Moinester
TAUOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about Abstract: The pion polarizability is of fundamental interes...» Abstract:
The pion polarizability is of fundamental interest in the low-energy sector of quantum chromodynamics. It is directly linked to the quark-gluon substructure and dynamics of the pion, the lightest bound system of the strong interaction. For more than a decade, COMPASS has been tackling the measurement of the electromagnetic polarizability of the charged pion, which describes the stiffness of the pion against deformation in electromagnetic fields. Previous experiments date back to the 1980's in Serpheukhov (Russia), where the Primakoff method for realizing interactions of charged pions with quasi-real photons was first employed. Later, other measurements based on photon-nucleon and photon-photon collisions were also carried out at different laboratories.
The COMPASS measurement demonstrates that the charged-pion polarizability is significantly smaller than the previous results, roughly by a factor two, with the smallest uncertainties realized so far.

The Problem of radiation-reaction
More information Time 16:15 - 17:00Location Tel Aviv University campusLecturer Yaron Hadad
TAUOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about The problem of radiation-reaction plagued classical electrom...» The problem of radiation-reaction plagued classical electromagnetism since it was introduced by Maxwell in 1861. Radiation-reaction is the recoil force exerted on an accelerating charge by its own radiation field.
In the last century radiation-reaction resisted more than a dozen of attempts on a solution, most notably by Dirac, Landau & Lifshitz.
In this talk, I will present a historical account of the problem of radiation-reaction, both in the context of classical and quantum electrodynamics. I will also discuss how radiation-reaction can finally be put to an experimental test using high intensity lasers.

Mechanisms of functional reprogramming in the tumor microenvironment
More information Time 10:00 - 11:00Location Wolfson Building for Biological ResearchLecturer Prof. Ruth Scherz-Shouval
Dept. of Biological Chemistry-WISOrganizer Department of Biomolecular SciencesContact Abstract Show full text abstract about For tumors to expand, metastasize, and evade immune surveill...» For tumors to expand, metastasize, and evade immune surveillance, genetically transformed cancer cells must recruit non-malignant cells, including macrophages, fibroblasts and endothelial cells. These cells, collectively termed the tumor microenvironment, are reprogrammed to support the tumor at the expense of its host. Our group aims to elucidate the mechanisms by which tumors reprogram their local environments. Our hypothesis is that cancer cells hijack normal cytoprotective stress responses, and subvert them to enable stromal reprogramming. In my talk, I will discuss the role of Heat-shock Factor 1 (HSF1), master regulator of the heat-shock response, in this process. Across a broad range of human cancers, HSF1 is activated in cancer-associated fibroblasts (CAFs), where it drives a transcriptional program that supports the malignant potential of adjacent cancer cells. In early stage breast and lung cancer, high stromal HSF1 activation is strongly associated with poor patient outcome. Thus, tumors co-opt the ancient survival functions of HSF1 to orchestrate malignancy, with far-reaching therapeutic implications. -

The SYK model correctly reproduces the Lyapunov exponent of a black hole, as computed from an out-of-time order 4-pt function. We will revisit some older matrix models, such as the one of Iizuka, Okuda, and Polchinski, and study the 4-pt function.. -

The six-dimensional field theories are (1, 0) supersymmetric and represent the low-energy dynamics of NS5-D6-D8-brane configurations. The gravity duals are AdS7 solutions of massive IIA supergravity. In addition, we present lower-dimensional anti-deSitter solutions, as duals to compactifications of the sixdimensional field theories. -

The Higgs Mass in Compact Supersymmetry
More information Time 11:00 - 11:00Location Edna and K.B. Weissman Building of Physical SciencesLecturer Kohsaku Tobioka
Weizmann/TAUOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about The current LHC results make weak scale supersymmetry diffic...» The current LHC results make weak scale supersymmetry difficult due to relatively heavy mass of the discovered Higgs boson and the null results of new particle searches. Geometrical supersymmetry breaking from extra dimensions, Scherk-Schwarz mechanism, is possible to accommodate such situations. A concrete example, the Compact Supersymmetry model, has a compressed spectrum ameliorating the LHC bounds and large mixing in the top and scalar top quark sector with |A_t |∼2m_t ̃ which radiatively raises the Higgs mass. While the zero mode contributions of the model has been considered, in this paper we calculate the Kaluza-Klein tower effect to the Higgs mass. Although such contributions are naively expected to be as small as a percent level for 10 TeV Kaluza-Klein modes, we find the effect significantly enhances the radiative correction to the Higgs quartic coupling by from 10 to 50 %. This is mainly because the top quark wave function is pushed out from the brane, which makes the top Yukawa coupling to depend on higher powers in the Higgs field for a fixed top mass. As a result the Higgs mass is enhanced up to 15 GeV from the previous calculation. We also show the whole parameter space is testable at the LHC run II.
