“Nonlinearity and Randomness in Many-Body Physics: Insights and Practical Applications”
Abstract:
Many-body physics is a rich field that connects diverse topics ranging from fundamental interactions to condensed matter physics and its engineering applications. Many-body theory is generally formulated in a linear framework. Nevertheless, randomness and strong nonlinearities are crucial aspects. I will present three case studies characterized by these aspects. First, I will revisit nonlinear quantum electrodynamics with applications to solids. Second, I will discuss hydrodynamics and its applications in electron transport theory. If time permits, I will explore nonlinear coupled oscillators in the context of inference and inverse problems, with applications in machine learning.
Aydın Cem Keser is a theoretical and applied physicist specializing in condensed matter systems. He earned his Ph.D. in Physics from the University of Maryland, College Park, focusing on quantum gases and disordered systems. His award-winning thesis is published by Springer as a monograph titled “Classical Analogies in the Solution of Quantum Many-Body Problems”. Dr. Keser has published extensively on many-body systems, providing insights into phenomena like hydrodynamic transport and nonlinear electromagnetic effects. He is currently a senior scientist specializing in quantum sensors at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Sydney. Dr. Keser is also an active science communicator and has a passion for teaching.
