Snapshots of quantum dynamics:  constraints, integrability and hidden orders

Snapshots of quantum dynamics: constraints, integrability and hidden orders

  • The Science Center of The CUNY Graduate Center (Rm 4102) (map)
  • Google Calendar ICS

This workshop is part of a continuing series of informal annual meetings on nonequilibrium quantum dynamics. Topics to be covered fall in four broad categories: (1) new concepts such as many-body quantum scars, fractons, and more generally the role constraints play in unconventional many-body quantum dynamics; (2) recent developments in integrable systems, particularly the understanding of diffusion and the dynamics of quantum information; (3) unifying the emerging understanding of dynamics in isolated quantum systems with what is known about the dynamics of dissipative systems; and (4) experimental developments in quantum gas microscopes and related settings that allow one to take single snapshots of many-body systems, and therefore enable one to probe new classes of theoretical objects, such as non-local order parameters and multipoint correlators.

Machine Learning and Statistical Physics

  • The Science Center (Rm 4102) at The Graduate Center, CUNY (map)
  • Google Calendar ICS

The recent surge of activity at the interface of statistical physics and machine learning has brought novel tools and ideas to both fields. Some examples include the information bottleneck appearing as a fundamental lens through which to view neural networks, the renormalization group as a conceptual basis for understanding deep learning, and the identification of phases of matter using methods of machine learning. This workshop brings together a number of researchers taking a statistical physics approach to machine learning with the intention of using insights from physics to understand learning systems.

Quantum and Classical Light-Matter Interactions

  • The Graduate Center, CUNY, Rm 9204 (map)
  • Google Calendar ICS

M Nov. 12 & T Nov. 13 (Rm 9204)

The interaction of light and matter has played a pivotal role since the early days of quantum mechanics. Experimental advances together with theoretical simulations in the past decade have led to the control of the dynamics of molecules, even at the attosecond time-scale, and in turn, using matter to generate light pulses with desired features. Strong light-matter coupling can be achieved by confining the system to a cavity, where even the vacuum field can modify molecular properties. The burgeoning field of “polaritonic chemistry” requires a full accounting of the correlated dynamics of electrons, nuclei, and photons. Experts will discuss state-of-the-art developments in fundamentals and applications of both quantum and classical light-matter interactions.

Bits and Biology

  • Google Calendar ICS

W Sept. 12 - F Sept. 14, in the Science Center (Rm 4102)

Much of the business of life is about the transmission and processing of information, but it is less clear what the full mathematical structure of information theory teaches us about the mechanisms at work in living systems. We use the 70th anniversary of Shannon’s foundational papers as an opportunity to address this question, across all scales from the folding of individual protein molecules to the dynamics of learning. We will explore the amount of information that is conveyed in these different processes, and the nature of its representation, using information theory as a tool for the characterization of biological systems. More deeply, we will explore examples where optimization of information transmission has been used as a principle from which aspects of biological function can be derived. Presentations will start with pedagogical background, and there will be ample opportunity for discussion.
