Tenure Trek: Navigating Academia Around the World

Prof. Dr. Giovanna Morigi (University of Saarland, Germany)
Prof. Dr. Anushya Chandran (Boston University, USA & MPI-PKS, Germany)
Dr. Ricardo Martinez-Garcia (CASUS & HZDR, Germany)

4:30 - 5:30 pm : colloquium "Search as (quantum) selforganized process" by Prof. Dr. Giovanna Morigi 5:30 - 6:00 pm : a coffee break 6:00 - 7:00 pm: Exploring academic systems, gender representation, and career strategies: insights from internationally experienced PIs, followed by a discussion. Abstract for the colloquium: Efficient retrieval of information is a core operation in the world wide web, is essential for the sustainance of living organism, and is a paradigm for optimization algorithms. Inspired by the food search dynamics of living organisms, we discuss a search on a graph with multiple constraints where the dynamics is a selforganized process resulting from the interplay of coherent dynamics and Gaussian noise. We show that Gaussian noise can be beneficial to the search dynamics leading to significantly faster convergence to the optimal solution. We then analyse how these concepts can be extended to quantum searches, cast in terms of spatial searches on a graph and discuss whether and when the efficiency of noise-assisted quantum searches can outperform the one of unitary protocols.

Tunable Matter -- Many More is More Different

Prof. Andrea J. Liu (University of Pennsylvania)

In 1972 Phil Andersen articulated the motto of condensed matter physics as “More is different.” However, for most many-body systems the behavior of a trillion bodies is nearly the same as that of a thousand. Here I argue for a class of condensed matter, “tunable matter," in which many more is different. The ultimate example of tunable matter is the brain, whose cognitive capabilities increase as size increases from 302 neurons (C. Elegans) to a million neurons (honeybees) to 100 billion neurons (humans). I propose that tunable matter provides a unifying conceptual framework for understanding not only a wide range of systems that perform biological functions, but also physical systems capable of being trained to develop special collective behaviors without using a processor.
