QCD Crossover at Finite Chemical Potential from Lattice Simulations.

We provide the most accurate results for the QCD transition line so far. We optimize the definition of the crossover temperature T_{c}, allowing for its very precise determination, and extrapolate from imaginary chemical potential up to real µ_{B}≈300 MeV. The definition of T_{c} adopted in this work is based on the observation that the chiral susceptibility as a function of the condensate is an almost universal curve at zero and imaginary µ_{B}. We obtain the parameters κ_{2}=0.0153(18) and κ_{4}=0.00032(67) as a continuum extrapolation based on N_{t}=10, 12, 16 lattices with physical quark masses. We also extrapolate the peak value of the chiral susceptibility and the width of the chiral transition along the crossover line. In fact, both of these are consistent with a constant function of µ_{B}. We see no sign of criticality in the explored range.

Lattice QCD and heavy ion collisions: a review of recent progress.

In the last few years, numerical simulations of Quantum chromodynamics on the lattice have reached a new level of accuracy. A wide range of thermodynamic quantities is now available in the continuum limit and for physical quark masses. This allows a comparison with measurements from heavy ion collisions for the first time. Furthermore, calculations of dynamical quantities are also becoming available. The combined effort from first principles and experiment allows us to gain an unprecedented understanding of the properties of quark-gluon plasma. I will review the state-of-the-art results from lattice simulations and connect them to the experimental information from the relativistic heavy ion collider and the large hadron collider.

Is there a flavor hierarchy in the deconfinement transition of QCD?

We present possible indications for flavor separation during the QCD crossover transition based on continuum extrapolated lattice QCD calculations of higher order susceptibilities. We base our findings on flavor-specific quantities in the light and strange quark sector. We propose a possible experimental verification of our prediction, based on the measurement of higher order moments of identified particle multiplicities. Since all our calculations are performed at zero baryochemical potential, these results are of particular relevance for the heavy-ion program at the LHC.

The Science Teaching Fellows Program: A Model for Online Faculty Development of Early Career Scientists Interested in Teaching.

The American Society for Microbiology (ASM) has a history of providing a wide range of faculty development opportunities. Recently, ASM developed the Science Teaching Fellows Program (STF) for early career biologists and postdoctoral students to explore student-centered teaching and develop the skills needed to succeed in positions that have a significant teaching component. Participants were selected to STF through a competitive application process. The STF program consisted of a series of six webinars. In preparation for each webinar, participants completed a pre-webinar assignment. After each webinar, fellows practiced what they learned by completing a post-webinar assignment. In a survey used to assess the impact of STF, participants reported greater knowledge of the webinar-based instructional topics and a sense of being part of an educational community and were more confident about varied teaching methods.
