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…

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…

Physics Colloquium: “Exploring emergent collective phenomena with ultracold atoms and photons” Presented by Dr. Hikaru Tamura - IMS

Location:

Lewis Lab 316

February 20, 2025, 4:25 - 5:25pm

Collecting many elements often gives rise to fascinating emergent phenomena that cannot be predicted from the individual elements. Understanding and controlling collective phenomena could potentially lead to the discovery of new properties and functionalities, advancing technologies…

Physics Colloquium: "Site-selective cavity readout of a neutral atom array" Presented by Dr. Josiah Sinclair - MIT

Location:

Lewis Lab 316

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

Recently, programmable arrays of single atoms have emerged as a leading platform for quantum computing and simulation with experiments demonstrating control over hundreds of atoms. Interfacing an atom array with a high-quality optical cavity promises even greater control and new…

Physics Colloquium: “How to survive in magnetic fields: A guidebook for superconductors” Presented by Dr. Sylvia Lewin - NIST

Location:

Lewis Lab 316

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

Superconductivity was first observed in 1911, and while a century of study has revealed a great deal about this exotic state of matter, much remains to be understood. Strong magnetic fields typically destroy superconductivity, yet in some materials superconductivity can survive under…

Location:

Lewis Lab 316

December 5, 2024, 4:25 - 5:25pm

Quark Gluon Plasma (QGP) is a primordial form of nuclear matter that filled the Early Universe. Advancements in particle accelerator technologies have made it possible to recreate and study this form of matter in a laboratory by colliding heavy ions at ultra-relativistic energies. For…

Physics Colloquium: "Can mind-revealing drugs revive the afflicted mind? – The effects of psychedelics and their analog on normal and stressed brains" Presented by Dr. Ju Lu - Lehigh University

Location:

Lewis Lab 316

November 21, 2024, 4:25 - 5:25pm

Stress pervades modern life. It affects various brain functions, posing risks for many psychiatric disorders. However, few therapeutics are available to combat such deleterious effects of stress. One class of candidate drugs are psychedelics. With potent effects on the human mind,…

Physics Colloquium: “Entanglement, von Neumann algebras, and the emergence of spacetime” Presented by Dr. Hong Liu - MIT

Location:

Lewis Lab 316

November 14, 2024, 4:25 - 5:25pm

Einstein's General Relativity says gravity is a manifestation of dynamic spacetime. There are, however, hints—particularly from string theory—that spacetime may be an emergent concept, analogous to fluids arising from large collections of molecules at macroscopic scales.
