"Floquet quantum states: topological transitions, steady states, and surprising implications"
Thursday, October 1, 2015
Alexander Polyakov, Princeton University
"In praise of quantum field theory"
Quantum field theory provides a universal language for very different areas of physics. I will try to demonstrate this by briefly discussing some fundamental problems, both solved and unsolved.
The problems will include (if time permits) critical phenomena and conformal bootstrap, quark confinement and gauge/string duality, cosmological constant and turbulence, and maybe more.

"The Universe as a Laboratory for Fundamental Physics: Recent results from Spider and prospects for future suborbital observations"
I will describe our recent cosmological results from observations of the Cosmic Microwave Background, including a status report on the recent flight of the Spider experiment, a balloon borne CMB polarimeter. I will also discus a convergence of observational needs and technological capabilities that provide intriguing opportunities for improving our understanding of both the late- and early-time evolution of the Universe.Host: Lyman Page, James S.

"What can theoretical physics do for biology (and vice-versa)? Reflections of an ex-particle theorist."
Living matter obeys the laws of physics, and the principles and methods of theoretical physics ought to find useful application in many areas of biology. This truism is becoming ever more relevant with the rapid growth of the ability of biological experiments to produce comprehensive quantitative data. After a broad survey of the theoretical questions that today's biology is bringing to the fore, I will tell you about my own attempts to deal with some of them, with a focus on cellular biology. I hope to convince you that theoretical physics and biology have much to offer each other, and that relations between them are destined to grow closer over time. I am certain that I can convince you that a good time will be had by all.

"Order from Chaos: From the Solar Cycle to the Jets on Jupiter"
The eleven year solar activity cycle is a remarkable example of regular behavior emerging from an extremely turbulent system. The jets on Jupiter sit unmoving on a sea of turbulent eddies. Astrophysical phenomena often display organization on spatial and temporal scales much larger than the turbulent processes that drive them. An outstanding problem of astrophysics (and indeed other branches of nonlinear physics) is how to describe the statistics of systematic behavior emerging from the underlying chaos, given that Direct Numerical Simulation of these objects is simply impossible. Here, I shall introduce these fascinating phenomena and describe how methods from non-equilibrium statistical mechanics and many body quantum systems may be developed to give some insight into their behavior.
