+ - A popular talk by Sabine Hossenfelder

How Beauty Leads Physics Astray by Sabine Hossenfelder. November 29th at 7PM in 208 Argyros Forum.

To develop fundamentally new laws of nature, theoretical physicists often rely on arguments from beauty. Simplicity and naturalness in particular have been strongly influential guides in the foundations of physics ever since the development of the standard model of particle physics. In this lecture, Dr. Hossenfelder argues that arguements from beauty have led the field into a dead end, and discusses what can be done about it.

+ - A popular talk from Dr. Philip Mannheim

Dr. Philip Mannheim, Professor of Physics at the University of Connecticut presents, "The Crisis in Fundamental Physics" on Friday, August 31st @ 330PM in 404 Beckman Hall.

 

Abstract: Cosmology deals with the astrophysical macroscopic universe on large scales, while fundamental physics deals with the particle physics microscopic universe on small ones. Recently, it has become apparent that large and small scale physics are actually intertwined, leading to an astro-particle picture of the universe. At the present time, this picture has achieved great success, but at the same it has led to many open questions and challenges - challenges which threaten to potentially undermine the entire picture. These challenges include: dark matter, dark energy, the cosmological constant problem, quantum gravity, the status of supersymmetry, the multiverse picture, extra space-time dimensions, and the nature of the Higgs boson. In this talk, we review these issues, and suggest that their resolution would require a paradigm shift in our view of the universe.

+ - A popular talk from Dr. Neil Turok


Dr. Neil Turok, Director of Perimeter Institute for Theoretical Physics in Waterloo, Canada, presents "Quantum Universe" on Thursday, March 1st @ 530PM in Fish Interfaith Center.

Abstract: Observations reveal the cosmos to be astonishingly simple, and yet deeply puzzling, on the largest scales. Why is it so nearly symmetrical? Why is there a cosmological constant, or dark energy, and what fixes its value? How did everything we see emerge from a singular "point" in the past?

 

+ - A popular talk by Dr. Andrew Jordan and Dr. Kater Murch


Dr. Andrew Jordan (University of Rochester) and Dr. Kater Murch (Washington University in St. Louis) present, "The arrow of time in quantum mechanics" 

Abstract: The question of why we perceive time moving from past to future is perplexing, especially in light of the fact that microscopic laws of motion are the same running forward or backwards in time. Some have thought that the answer to this puzzle may lay in quantum wavefunction collapse. We will discuss how recent experiments have shown that quantum measurement may not be as irreversible as commonly thought, and discuss deep questions relating to the flow of time and quantum physics. We will approach the topic from three points of view, that of the experimentalist, the quantum theorist, and the philosopher.

+ - A technical talk from Dr. Alyssa Ney


Dr. Alyssa Ney (from UC Davis) presents, "Physics and Fundamentality"

Abstract: What justifies the allocation of funding to research in physics when many would argue research in the life and social sciences may have more immediate impact in transforming our world for the better? Many of the best justifications for such spending depend on the claim that physics enjoys a kind of special status vis-a-vis the other sciences, that physics or at least some branches of physics exhibit a form of fundamentality. The goal of this paper is to articulate a conception of fundamentality that can support such justifications. I argue that traditional conceptions of fundamentality in terms of dynamical or ontic completeness rest on mistaken assumptions about the nature and scope of physical explanations.

+ - A technical talk by Dr. Kater Murch


Dr. Kater Murch (from Washington University in St. Louis) presents, "Measurement and control in superconducting qubits: from the quantum Zeno effect to quantum enhanced metrology"

Abstract: The quantum Zeno effect is a feature of measurement-driven quantum evolution where frequent measurement inhibits the decay of a quantum state. We will explore how the opposite effect; the anti-Zeno effect - where frequent measurement accelerates decay - can also emerge from frequent measurement. The emergence of one effect or the other elucidates the nature of quantum measurement and the role measurement plays in controlling quantum evolution. In a second experiment, we investigate how control over a single qubit can be used achieve a quantum speedup in the precision of frequency measurements, demonstrating a frequency sensitivity that improves as 1/T^2, where T is the duration of the experiment.

A Few Physics Wonders - Superoscillations series - Divergent series -

berry

Sir Michael Berry came visiting Chapman campus ready to talk about some of the beautiful things that physicists actually do. Intentionally accessible to anybody, this free and open to the community colloquium uses non-technical language and a multi-media experience. A Few Physics Wonders is generally appealing to an audience interested in science, especially those who find the work of other great physicists, like Einstein or Hawking, inspirational.

Following his fun, standing-room-only popular talk, Sir Michael Berry hosted an open, five-part series of technical seminars focused on Superoscillations, and concluded with a supplementary sixth presentation from his Divergent Series: From Thomas Bayes's Bewilderment to Today's Resurgence Via the Rainbow.
