# Monday Colloquium: Martin Bazant (MIT) "Beyond Six Feet: A Guideline to Control Indoor Airborne Transmission of COVID-19"

4:30pm

## Location:

Zoom

The current revival of the American economy is being predicated on social distancing, notably the Six-Foot Rule of the CDC, which offers little protection from pathogen-bearing aerosol droplets sufficiently small to be mixed through an indoor space. The importance of indoor airborne transmission of COVID-19 is now widely recognized, but no simple safety guideline has been proposed to protect against it. We here build upon models of airborne disease transmission to derive a guideline that bounds the cumulative exposure time", the product of the number of occupants and their time...

# Monday Colloquium: Trevor David Rhone (RPI) "Data-driven studies of magnetic van der Waals materials"

4:30pm

## Location:

Zoom
When the dimensionality of an electron system is reduced from three dimensions to two dimensions, new behavior emerges. This has been demonstrated in gallium arsenide quantum Hall systems since the 1980’s, and more recently in van der Waals (vdW) materials, such as graphene. The discovery of vdW materials with intrinsic magnetic order in 2017 has given rise to new avenues for the study of emergent phenomena in reduced dimensions. These materials are at the forefront of condensed matter physics research. How many vdW magnetic materials exist in nature? What are their properties? How do these...

# Monday Colloquium: Janet Conrad (MIT) "Of Elephants and Oscillations"

4:30pm

## Location:

Zoom

This talk explores next steps in the search for new physics in the neutrino sector. The discovery of neutrino oscillations has changed the way we think about our model of particle physics. We must now incorporate tiny neutrino masses into our theory, as well as consider the possibility of other unexpected properties. You might ask what a tiny mass particle has to do with elephants? To learn this, you need to come to the colloquium.

# Physics Monday Colloquium: Kang-Kuen Ni (Harvard University) "Bringing Together Quantum Chemistry and Physics with Ultracold Molecules"

4:30pm

## Location:

Zoom

Advances in quantum manipulation of molecules bring unique opportunities, including the use of molecules to search for new physics, harnessing molecular resources for quantum engineering, and exploring chemical reactions in the ultra-low temperature regime. In this talk, I will focus on the latter two topics. First, I will introduce our effort on building single ultracold molecules with full internal and motional state control in optical tweezers for future quantum simulators and computers. This work allows us to go beyond the usual paradigm of chemical reactions that proceed via...

# Monday Colloquium: Maria Fyta (Universitat Stuttgart) "Nanometer-sized holes opened in materials for molecular detection"

4:30pm

## Location:

Zoom

Nanometer-sized holes can be opened in materials in order to detect single molecules, sequence DNA and RNA or store information. Using computational means at various spatiotemporal levels, we attempt to understand the characteristics of nanopores in different materials in order to tune their detection efficiency and biosensitivity. On top of these, Machine Learning approaches have allowed us to interpret relevant experimental data and provide us with predictions on the identity of the molecules threading the pores. We discuss what we have learned so far and the relevance of our work in...

# Monday Colloquium: Chanda Prescod-Weinstein (University of New Hampshire) "Large Scale Structure from Microphysics"

4:30pm

## Location:

Zoom

In this talk, I will describe my efforts to understand the nature of the mysterious dark matter. I provide an overview of the general problem and then describe my current approach to it, which is to characterize the behavior of a proposed dark matter particle, the axion. I will give some insight into how I am using a range of tools -- model building, computation, and high energy astrophysics -- to get at the basic question of “what is the statistical mechanics of axion dark matter?” I will discuss work that shows that the self-interaction should not be ignored and that the sign of the...

# Monday Colloquium: Isaac Chuang (MIT) "Grand unification of quantum algorithms"

4:30pm

## Location:

Zoom

Modern quantum algorithms with provable speedups originate historically from three disparate origins: simulation, search, and factoring. Today, we can now understand and appreciate all of these as being instances of a single framework, recently created by Gilyen, Su, Low, and Weibe, based on two key ideas: (1) the transformability of singular values by quantum evolution, and (2) the nonlinearity available to process two-level quantum signals. This remarkable unified framework opens doors to new quantum algorithms, provides opportunities for quantum advantage, and introduces questions...
