Physics Colloquium: "High rank multipole order: feeling the strain" Presented by Dr. Ian Fisher - Stanford University

Location:

Lewis Lab 316

November 13, 2025, 4:25 - 5:25pm

Interactions can lead to a wide variety of ordered states in materials. Phase transitions in which local atomic states develop spontaneous high rank multipole order provides a particularly rich arena for new insights. A key element in the study of such systems is the ability to couple…

Physics Colloquium: "Resolving the Proton Spin Puzzle: Insights from RHIC and the Road to the EIC" Presented by Dr. Kenneth Barish- UC Riverside

Location:

LL 316

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

The proton is a composite object, consisting of quarks and gluons, that possesses an intrinsic angular momentum, or spin. As a fundamental quantum mechanical property, spin profoundly influences the proton’s physical characteristics, including its optical, electrical, and magnetic…

Physics Colloquium: May the Force Be with Her: Nuclear Envelope Dynamics in C. elegans Oocyte Development" Presented by Dr. Chenshu Liu - Lehigh University

Location:

Lewis Lab 316

October 30, 2025, 4:25 - 5:25pm

Sexual reproduction depends on meiosis—the specialized cell division that halves the chromosome number—and the successful maturation of oocytes into viable eggs. In humans, this is an unusually prolonged process that can take up to 50 years to complete. Errors during meiosis or oocyte…

Physics Colloquium: “Phases: Geometric, topological and localized” Presented by Dr. Rahul Roy - UCLA

Location:

Lewis Lab, 316

October 23, 2025, 4:25 - 5:25pm

What makes one phase of matter different from another? For much of physics, the answer has been guided by symmetry and its breaking. Yet we now know that this is only part of the story. Topological phases of matter defy this framework: they can have no local order parameter and yet…

Physics Colloquium: “Exploring order and disorder in quantum and classical networks” Presented by Dr. Bryce Gadway - Penn State

Location:

Lewis Lab 316

October 16, 2025, 4:25 - 5:25pm

Interactions can lead to ordering and synchronization in a range of physical systems, from the flocking of birds to the alignment of spin domains in magnets. Understanding the mechanisms for stabilizing or destabilizing synchronization and ordering is important in the classical world,…

Physics Colloquium: "Quantum geometry beyond single flat bands and Euler exact projected entangled pair ground states" Presented by Dr. Robert Jan-Slager - Cambridge

Location:

Lewis Lab, 316

October 9, 2025, 4:25 - 5:25pm

The past few years have seen a revived interest in quantum geometrical characterizations. Although the metric tensor has been connected to many geometrical concepts for single bands, the exploration of these concepts to a multi-band paradigm still promises a new field of interest. I…

Event

Physics Colloquium: "Back to fundamental QCD - a tale of quarks and gluons!" Presented by Dr. Rithya Kunnawalkam Elayavalli - Vanderbilt University

Location:

Lewis Lab, 316

October 2, 2025, 4:25 - 5:25pm

Collider experiments have proven themselves immensely useful in studying the behavior of fundamental particles such as quarks and gluons. The last few years in particular have seen a push towards an exploration of QCD, the theory of strong interactions, that has hitherto been…

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

Location:

Lewis Lab, 316

September 25, 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…

Physics Colloquium: “Large Quantum Gravity Effects” Presented by Dr. Finn Larsen - University of Michigan

Location:

Lewis Lab, 316

September 18, 2025, 4:25 - 5:25pm

It is common lore that quantum theory and gravity are somehow incompatible, and quantum gravity effects would anyway be so small that the subject is moot. This colloquium describes the theoretical status of quantum gravity, drawing on analogies with condensed matter physics and…

Physics Colloquium: "Quantum Computing Optimization: QUBO reformulations of combinatorial problems" Presented by Dr. Luis Zuluaga - Lehigh Engineering

Location:

Lewis Lab 316

September 11, 2025, 4:25 - 5:25pm

Quantum computing (QC) harnesses the properties of subatomic particles to perform computations in a fundamentally different way than classical computing. QC has the potential to make a revolutionary impact on the way we model, and subsequently solve real-world optimization problems…

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…
