Physics Colloquium: "Physics for Deep Learning: Towards a Theoretical Foundation" Presented by Dr. Yuhai Tu - Flatiron Institute

Location:

Lewis Lab, 316

September 4, 2025, 4:25 - 5:25pm

Artificial Neural Network (ANN) and Machine Learning (ML) have received a huge amount of attention amongphysicists triggered by the 2024 Nobel Physics Prize to John Hopfield and Geoff Hinton. Historically, ANN-based ML wasdeveloped based on ideas from neuroscience and statistical…

Physics Colloquium: "Making ordered phases of matter at arbitrarily high temperature" Presented by Dr. Andrew Lucas - University of Colorado, Boulder

Location:

Lewis Lab, 316

August 28, 2025, 4:25 - 5:25pm

Usually in statistical physics, high temperature phases are disordered and featureless while low temperature phases are ordered.  For example, solid ice becomes liquid water upon heating; the solid is an ordered phase that spontaneously breaks translational and rotational…

Physics Colloquium: "Fermions in an Optical Box" Presented by Dr. Nir Novan - Yale University

Location:

LL 316

May 1, 2025, 4:25 - 5:25pm

For the past two decades harmonically trapped ultracold atomic gases have been used with great success to study fundamental many-body physics in flexible experimental settings. However, the resulting gas density inhomogeneity in those traps has made it challenging to study…

Event

Physics Colloquium: "Cellular protrusion generation and length scale depend on curvature cues and actin network balances" Presented by Dr. Michael Henderson - Bowdoin College

Location:

LL 316

April 24, 2025, 4:25 - 5:25pm

Some of the most noticeable changes in the shape of a cell membrane are the formation of finger-like protrusions such as short filopodia (typically <5 μm long) that assist in environmental sensing and cell migration or tunneling nanotubes (TNTs) that connect cells up to 100 μm away…

Physics Colloquium: "Exploring Intrinsic Disorder at the Protein-Lipid Interface" Presented by Dr. Wade Zeno - University of Southern California

Location:

LL 316

April 17, 2025, 4:25 - 5:25pm

Cellular membranes are critical interfaces for the biochemical interactions that regulate cell behavior and function. Composed of heterogeneous mixtures of lipids and proteins, these membranes create complex environments where protein-lipid interactions are functionally coupled,…

Lecture

Physics Colloquium: "3D printing cytoskeletal networks: ROS-induced filament severing leads to surge in actin polymerization" Presented by Dr. Thomas Lischel

Location:

Lewis Lab 316

April 10, 2025, 4:25 - 5:25pm

The cytoskeletal protein actin forms a spatially organized biopolymer network that plays a central role in many cellular processes. Actin filaments continuously assemble and disassemble, enabling cells to rapidly reorganize their cytoskeleton. Filament severing accelerates actin…

Physics Colloquium: "Two-channel Kondo Physics: from intrinsic criticality to unconventional orders" Presented by Dr. Rebecca Flint - Iowa State

Location:

LL 316

April 3, 2025, 4:25 - 5:25pm

The interactions between local moments and itinerant electrons gives rise to a rich array of ``Kondo'' physics, from heavy Fermi liquids to unconventional superconductivity and quantum criticality.  Here, I'll introduce the even richer two-channel Kondo physics, where two…

Event

Physics Colloquium: "Tiny universes from ensembles of open quantum systems" Presented by Dr. Sarah Shandera - Penn State

Location:

LL 316

March 27, 2025, 4:25 - 5:25pm

Gravity creates space-time boundaries that limit observables without limiting the flow of energy and information. This means that quantum systems in cosmology are often open systems: to describe them we must allow for the effects of interaction with an unobservable environment. In…

Physics Colloquium: "Inferring biophysical models from multi-omics data" Presented by Dr. Surya Maddu - Flatiron Institute

Location:

Lewis Lab 316

March 6, 2025, 4:25 - 5:25pm

The rapid advancements in high-throughput imaging and sequencing technologies have led to an explosion of omics data in biology, encompassing genomics, transcriptomics, proteomics, metabolomics, and beyond. However, extracting mechanistic insights requires more than just data…

Physics Colloquium: “Exploring emergent collective phenomena with ultracold atoms and photons” Presented by Dr. Jun Yi Lee - IMRE

Location:

Lewis Lab 316

February 27, 2025, 4:25 - 5:25pm

Atomic vapor cells can contain a relatively large number of coherent atoms within convenient and compact form factors, which enables them to be used in diverse applications. For example, alkali-noble gas co-magnetometers can be used to search for new physics beyond the Standard Model…

Physics Colloquium: "Utilizing strain to probe nematic quantum criticality and beyond" Presented by Dr. Elliot Rosenberg - University of Washington

Location:

Lewis Lab 316

February 25, 2025, 4:25 - 5:25pm

Nematic order, which is characterized by rotational symmetry breaking, and its corresponding fluctuations, may play crucial roles in the phase diagrams of high Tc superconductors. In particular, it has been suggested that the nematic quantum critical fluctuations arising from a…
