“Imaging a Landscape of Ferromagnetism, Paramagnetism, and Diamagnetism in LAO/STO Interfaces”‬
More information Time 13:00 - 13:00Lecturer Kathryn Moler
Stanford UniversityOrganizer Department of Condensed Matter PhysicsContact Abstract Show full text abstract about LaAlO3 (LAO) and SrTiO3 (STO) are both nonmagnetic band insu...» LaAlO3 (LAO) and SrTiO3 (STO) are both nonmagnetic band insulators, yet previous experimental and theoretical work has indicated the existence of a conducting (even superconducting) state at the interface, and suggested the possibility of ferromagnetism. We use scanning SQUID microscopy to image the magnetic behavior on micron length scales. We find three types of magnetic behaviors: weak, inhomogeneous diamagnetism consistent with superconductivity below 100 mK; a low-temperature 1/T-like paramagnetic response suggestive of a fairly uniform density of isolated spins; and ferromagnetic patches that are stable up to at least 60 Kelvin. The variety of details in reports of magnetism, including our observation of a landscape (rather than a homogeneous phase), support the exciting possibility that multiple states are important in this engineered interface. I will also discuss our recent unpublished results on the ferromagnetism's dependence on various parameters and sample conditions and on the superconductivity in which we image the landscape of superfluid density while tuning the critical temperature with gate voltage. -

Recently, it was extracted for the first time from the Lamb shift in muonic hydrogen. For a long time it was anticipated that such a measurement would reduce the error by an order of magnitude compared to measurements from electron- proton scattering and regular hydrogen spectroscopy. While this goal was achieved, the value of the proton's charge radius that was obtained was, very surprisingly, five standard deviations away from the world average.
The extraction of the charge radius from the Lamb shift in muonic hydrogen depends on a theoretical input. Together with Richard J. Hill, we are studying the hadronic uncertainty in the theoretical prediction using the tool of an effective field theory, namely NRQED. In the talk I will describe the results of this study. I will also describe a previous study of the model-independent extraction of the charge radius from electron-proton scattering We have shown that previous extractions, spanning a period of over 40 years, have underestimated their error sometimes by a factor of two or more.

"Direct Photons in Heavy Ion Collisions"
More information Time 16:15 - 17:15Location Edna and K.B. Weissman Building of Physical SciencesLecturer Zvi Citron
Weizmann InstituteOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about Direct photons are a key probe for understanding the hot den...» Direct photons are a key probe for understanding the hot dense matter created in heavy ion collisions. The signature result of heavy ion experiments thus far, is the dramatic modification of the production of strongly interacting particles in the hot and dense medium. Since the photon does not undergo any strong force interactions, it emerges from the medium unmodified and is a clean probe which can be contrasted to measured jets and strongly interacting particles. In particular, photon-jet correlations have been referred to as a golden channel in heavy ion collisions. In a photon-jet event the unmodified photon allows us a direct insight into the modification of the opposite side jet. The results from RHIC and LHC will be discussed. -

School of Chemistry at Tel-Aviv UniversityOrganizer Department of Molecular Chemistry and Materials ScienceContact Abstract Show full text abstract about Salalens are tetradentate dianionic sequential {ONN'O}-...» Salalens are tetradentate dianionic sequential {ONN'O}-type ligands that lead to octahedral complexes of group 4 metals of the type [{ONN'O}MX2] of fac-mer geometry and C1-symmetry. We have recently developed an efficient methodology for the synthesis of Salalen ligands that enables the fine-tuning of steric and electronic parameters. We found that several titanium complexes of these ligands led to highly active catalysts for polymerization of alpha-olefins, and, most importantly, to polypropylene with very high isotacticities, reaching [mmmm] > 99.6% and melting transitions of up to 169.9 °C, which is unprecedented, to our knowledge. In this presentation we will describe the design principles that have led to this development, and, as time allows, the development of other homogeneous catalysts for stereoregular polymerization. -

A minimal dynamical model that reproduces the statistical features of experimental trajectories, is deduced from trajectory data. This model extends the cell-type specific models derived for mammalian cells a few years ago.
