These include X="Catalysis" and X="Screening". I will also describe some work in progress with X="Electron Stars" in which the gravitational backreaction of fermions in the lowest Landau level is computed through bosonization. -

Bird's Brain? Possible relations between behavior and brain plasticity
More information Time 12:30 - 12:30Location Gerhard M.J. Schmidt Lecture HallLecturer Prof. Anat Barnea
Dept of Natural and Life Sciences The Open University of IsraelOrganizer Department of Brain SciencesContact Abstract Show full text abstract about Neurogenesis (birth of new neurons) occurs in many vertebrat...» Neurogenesis (birth of new neurons) occurs in many vertebrates, including humans. Most of the new neurons die before reaching destination. Those which survive migrate to various brain regions, replace older ones and connect to existing circuits. Evidence suggests that this replacement is related to acquisition of new information. Therefore, neuronal replacement is seen as a form of brain plasticity that enables organisms to adjust to environmental changes. However, direct evidence of a causal link between replacement and learning remains elusive.
I will review a few of our studies which tried to uncover conditions that influence new neuronal recruitment and survival, and how these phenomena relate to the life of birds. The hypothesis is that an increase in new neuron recruitment is associated with expected or actual increase in memory load, particularly in brain regions that process and perhaps store this new information. Moreover, since new neuronal recruitment is part of a turnover process, we assume that the same conditions that favor the survival of some neurons induce the death of others.
I will offer a frame and rational for comparing neuronal replacement in the adult avian brain, and try to uncover the pressures, rules, and mechanisms that govern its constant rejuvenation. I will discuss a variety of behaviors and environmental conditions (especially birds' migration, and if time permits - parent-offspring recognition) and their effect on new neuronal recruitment in relevant regions in the avian brain. I will describe various approaches and techniques which we used in those studies (behavioral, anatomical, cellular and hormonal), and will emphasize the significance of studying behavior and brain function under natural or naturalistic conditions.

Observing the Growth of the Most Massive Black Holes at High Redshifts

TAUOrganizer Nella and Leon Benoziyo Center for AstrophysicsContact Abstract Show full text abstract about There is ample evidence that the most significant growth epo...» There is ample evidence that the most significant growth epoch of the majority of super-massive black holes (SMBHs) must have occurred at z>1-2.
I will present our team's efforts to measure black hole masses and accretion rates in several high-redshift samples of AGNs, based on extensive NIR spectroscopic campaigns. I will particularly focus on a large sample of z~5 AGNs, which were observed in a combined VLT-Gemini campaign. This sample probes the most massive BHs at this epoch, but shows lower masses and higher accretion rates than those of z~2-3.5 sources. When combining these samples together, a clear evolutionary sequence is evident: the z~5 BHs grow through Eddington-limited accretion from a broad range of seed masses; their subsequent growth, at duty cycles of ~10-20%, forms the most massive BHs observed at z~2. I will also mention a few follow-up campaigns which aim at understanding the co-evolution of these BHs with their host galaxies. -

In my talk I'll report about a model with strong spin-orbit interactions where a macroscopic diamagnetic response is induced which is independent of the gap. I discuss the evolution of the response as a function of a tuning parameter which brings the system from a topologically trivial via a strong topological insulator to a weak topological insulator. -

Magnetism in quantum gases

BerkeleyOrganizer Faculty of PhysicsContact Abstract Show full text abstract about With quantum gases, one can explore magnetic ordering and dy...» With quantum gases, one can explore magnetic ordering and dynamics in regimes inaccessible in solid-state systems. For example, in degenerate spinor Bose gases, magnetization of the atomic spin is established parasitically along with Bose-Einstein condensation, allowing minute spin-dependent energies to dictate the magnetic ordering of the gas. In addition, the extreme isolation of the atomic system allows for systems to created far out of equilibrium, allowing the dynamics of symmetry breaking to probed in real time. A second cold-atom "material," in which atoms are confined within the periodic potential of an optical lattice, bears a stronger resemblance to condensed-matter systems. I will present recent progress to explore the effects of geometric frustration with cold atoms that are confined in a two-dimensional kagome optical lattice.
