How much of a meritocracy? Untangling the drivers of productivity and prominence among scientists"

When
-

Coffee, tea and cookies will be available in G1B31 (across from G1B20) from 3:30–3:50 p.m.

==========

Abstract: Abstract: Simple measures of the productivity and prominence vary enormously across both individual scientists and across institutions. But, how much do these sometimes enormous inequalities represent genuine meritocratic differences, and how much are they biased by non-meritocratic factors that may limit scientific progress?

Quantum Simulation - from Dipolar Quantum Solids to Kinetic Nagaoka Ferromagnetism

When
-

Abstract: Quantum simulations with ultracold atoms in optical lattices enter the next phase, in which we can extend bosonic and fermionic Hubbard models in a wide range of ways. I will present recent results in which we realized strongly correlated dipolar quantum gases and observed quantum-phase transitions to stripe and checkerboard phases.

Relativistic Fluid Dynamics: From Particle Colliders to Neutron Star Mergers

When
-

Abstract: Heavy-ion collision experiments have provided overwhelming evidence that quarks and gluons, the elementary particles within protons and neutrons, can flow as a nearly frictionless, strongly interacting relativistic liquid over distance scales not much larger than the size of a proton. On the other hand, with the dawn of the multi-messenger astronomy era marked by the detection of a binary neutron star merger, it became imperative to understand how extremely dense fluids behave under very strong gravitational fields.
