How Costly is Your Brain's Activity Pattern? - Dani Bassett

Dani Bassett
(University of Pennsylvania.)
Further Information

Neural systems in general - and the human brain in particular - are organised as networks of interconnected components. Across a range of spatial scales from single cells to macroscopic areas, biological neural networks are neither perfectly ordered nor perfectly random. Their heterogeneous organisation supports - and simultaneously constrains - complex patterns of activity. 

How does the network constraint affect the cost of a specific brain's pattern? In this talk, Dani will use the formalism of network control theory to define a notion of network economy and will demonstrate how the principle of network economy can inform our study of neural system function in health and disease and provide a useful lens on neural computation.

Dani Bassett is the J. Peter Skirkanich Professor at the University of Pennsylvania. In 2016, Dani was named one of the ten most brilliant scientists of the year by Popular Science magazine and in 2018 received the Erdős–Rényi Prize for fundamental contributions to our understanding of the network architecture of the human brain.

How to get an interacting conformal line defect for free theories

Christopher Herzog
(KCL )
Abstract
We argue that interacting conformal line defects in free quantum field theories can exist, provided that correlation functions are not invariant under inversion symmetry.  Important for our demonstration is the existence of a special cross ratio for bulk-defect-defect three point functions that is invariant under the conformal group but picks up a sign under inversion. We examine the particular case of a free scalar field in detail, and we provide a toy model example where this bulk field interacts via a Yukawa term with fermions on the line.  We expect nontrivial line defects may also exist for free Maxwell theory in four dimensions and free bulk fermions.  Based on 2510.02871.
