The theory has many aspects in common with single- and multi-centered black hole solutions of $ mathcal{N}=2 $ supergravity in 4d. Specifically, there are bound states in both cases and microstates degeneracy are similar in special circumstances. Moreover, there is a scaling limit of multi-centered black holes in which the asymptotic become AdS$_2times $S$^2times$CY$_3$. The same limit exists in Coulomb branch quiver quantum mechanics. It has already been shown that a 3-node quiver in this limit adm ... 15:00 - 17:00 IPM SCS Free Webinars Effect of Conceptual Metaphors on Memory: A Preliminary study School COGNITIVE SCIENCES IPM SCS Free Webinars Abstract: The nature of metaphor, metaphor understanding, and its functions have been recognized as three main issues in research and theoretical formulations on metaphor and metaphor processing (Allbritton, 1995). In general, metaphor is defined as understanding and experiencing one thing based on another (Lakoff and Johnson, 1980/2003: 5). From the point of view of cognitive science, there are at least two main and distinct questions about metaphor: A. What processes does metaphorical understanding require? And B- What role does metap ... 19:30 - 21:30 IPM-SUT Joint IRQM Webinars on Quark matter and Relativistic hydrodynamics Core meets Corona: Lambda and anti-Lambda polarization in peripheral high-energy heavy-ion collisions School PARTICLES AND ACCELERATORS Abstract: The STAR Beam Energy Scan program has found a remarkable behavior for the global polarization of Lambdas and anti-Lambdas produced in peripheral high-energy Au + Au collisions: the latter is larger than the former for lower collision energies and the difference decreases with increasing collision energy. In this talk, I show that a two-component source to model the collision region, consisting of a high-density core and a lower density corona, can quantitatively describe the behavior of these polarizations as functions of the collision energy. The calculation makes use of the relaxation times that s-quarks and s-antiquarks produced ... |
