Review finance statement of DCMMP

Discuss if need to increase membership

CAP 2021 Congress:

  • Discuss “venue” (most likely, online)
  • Discuss “content” (plenary, invited speaker, symposium, contributed, student competition)
  • In the context of symposium/symposia: discuss “hard” CMP and “soft” CMP symposia.

“Soft Matter Canada”:

  • For consultation/information at this time: is there incentive/interest/merit split DCMMP such that two it would have two “sub-divisions”: “hard” and “soft”. Discuss relevance, or not to biophysics.
  • Discuss DCMMP Chair, vice-chair, etc for 2020/2021. Discuss in context of “aborted 2020 in-person context”.

Other businesses arising

Adjourn by ~4:00PM


Abstract:

Recently, magnon excitations have been explored as a potential route to realizing analogues of the topological band structures that have become ubiquitous in electronic systems.  However, magnons are not necessarily stable quasi-particles, with spontaneous magnon decay a generic feature of anisotropic magnets, or magnets with non-colinear order. In this talk I will show how, instead of being a detriment, decay can drive the appearance new kinds of intrinsically non-Hermitian topological physics. This can lead to new kinds of spectral features, such as exceptional points or lines and bulk “arcs” connecting them. I will illustrate this physics through a concrete example: a honeycomb ferromagnet with Dzyaloshinskii-Moriya exchange, comparing interacting spin-wave calculations with an effective non-Hermitian model. Finally, I discuss more broadly how the zoo of known topological protected magnon band structures may serve as a nearly ideal platform for realizing non-Hermitian physics in solid-state systems.

How the COVID-19 pandemic is affecting women in STEM

The COVID-19 pandemic has touched everyone’s lives, but it has not affected everyone equally. Madonna called COVID-19 “the great equalizer,” but she was wrong: the risk and severity of the disease itself, and the pandemic’s economic and social impacts, vary with age, income, race, and gender. The pandemic has laid bare and often worsened many pre-existing inequalities in our world. One issue of longstanding concern is gender equality, and I will discuss why the pandemic has the potential to worsen gender gaps in STEM fields. Data from several sources, including my own preliminary analysis of preprint submissions to arXiv and bioRxiv broken down by gender, suggest that women are getting less research done than men during the pandemic. I will explore several possible explanations for this trend, including an increased child care burden, and lead the group in a discussion of possible solutions.

DPE (Division of Physics Education) – Meet and Greet, Annual Business Meeting, and Workshops and Discussions about online teaching and learning:

Mon, June 15, 12h30-16h00 EDT

Session Schedule:

12h30-13h00 EDT :  Meet and Greet
13h00-14h00 EDT :  DPE Annual Business Meeting
14h00-16h00 EDT :  Discussions about online teaching and learning

The two hour session is intended to generate a lively discussion of various aspects of online teaching and learning.  The DPE Executive have planned for about 30 minutes each for

  • General course design and how to get students engaged
  • Assessment options and how to avoid cheating
  • Labs for lower level and upper level courses – how to achieve the various learning goals
  • TAs – what do they struggle with, and how do you support them?

For all topics, the organizers are looking for a few people who are interested in sharing their favorite idea, or most spectacular failure (which may be the same) – in 3 minutes or less.  If you would like to contribute, please contact the DPE Chair, Dr. Daria Ahrensmeier (daria_ahrensmeier@sfu.ca).
