Atom interferometry on narrow intercombination transitions of alkali-earth atoms

Nicola Poli,
University of Florence

Abstract/Details

A reception for Professor Poli will begin in the H Bar at 3:30pm. Abstract Today, matter-wave interferometers as clocks and gravimeters allow for precision measurements of time and gravity at unprecedented level.  In all these sensors, indeed, the exquisite control of both internal (electronic) and external (center of mass motion) degrees of freedom of ultra-cold atomic samples, enable us to study interactions at their most basic, quantum level, paving the way for new tests of fundamental physics.  In this talk, I'll review some of the most recent results obtained by our group in this field, presenting also a novel approach to atom interferometry, based on ultra-narrow intercombination transitions of strontium atoms (88Sr). Novel spin-squeezing techniques with direct application to strontium atom interferometers will also be discussed.   References N. Poli, F.-Y. Wang, M. G. Tarallo, A. Alberti, M. Prevedelli, G. M.

A First Characterization of Tidal Disruption Events and Their Surprising Properties

Iair Arcavi ,
University of California, Santa Barbara

Abstract/Details

The search for the tidal disruptions of stars by supermassive black holes (tidal disruption events; TDEs) is now yielding exciting results. In recent years, both gamma- and x-ray candidates as well as optical+UV events have been discovered, and a tantalizing connection to extreme coronal light emitters has been made. It is still not clear what the connection between these very different types of TDE candidates is, but recently we were able to tie several of the optical+UV events together into a coherent class of outbursts. This picture immediately offered two new insights. First, TDE emission properties are not as expected - our set of objects which all peak in the near UV rather than the expected x-rays, show lower than expected velocities and span an unexplained continuum of spectral classes from H-rich to H-poor. The second insight relates to the host galaxies - optical+UV TDEs show a strong (200x!) and unexpected preference for post-starburst galaxies. The reason for this is still not clear. We are collecting more and more observations of TDEs as they are discovered by wide field transient surveys and by our own first- ever specialized survey for TDEs. Understanding TDE emission properties and their peculiar host galaxy preference has far reaching implications for studying quiescent massive black holes, accretion physics and galaxy dynamics.
