|---|---|---|
| Sn-Pb binary and mixed-halide perovskite thin films by low-pressure chemical vapor deposition |
Since its first application as light absorbing materials in photovoltaic technology, perovskite solar cells (PSCs) have achieved a remarkable certified record power conversion efficiency (PCE) of over 25% in just over a decade. However, hybrid perovskite absorbers… Show more Speaker: Prof. Christopher Arendse |

| A Semi-Localized Transport (SLoT) Model for Chemically Doped Semiconducting Polymers |
Chemically doped semiconducting polymers exhibit electronic transport characteristics that range from localized (or hopping-like) transport to delocalized (or metal-like) transport. While a multitude of electronic transport models have been proposed, none of them… Show more Speaker: Prof. Shannon Yee |

| Quantum Mechanics in Phase Space |
TBA
Speaker: Prof. Thomas Curtright, University of Miami |
|
| Magnetism in Nanostructures studied with Neutron Scattering |
Magnetic systems on the range of nanometers are of great interest for application as well as fundamental physics. When macroscopic magnetic materials are scaled down to the nanoscale the energy balance changes and single-domain and super-paramagnetic states arise.… Show more Speaker: Dr. Artur Glavic |
|
| Transition Metal Ions in Molten Salts: Octahedral Networks and Intermediate-Range Order |
The microscopic structure and dynamics of molten salts is a fascinating subject. It is a very diverse family of materials; while molten NaCl is a simple mix of single-valence ions with a minimal structural organization, transition-metal ions form chains of octahedra… Show more Speaker: Boris Khaykovich |

| Physics majors present their research |
Ben Krewson: Defect Dynamics and Selection for Quenched Striped Patterns
We study transverse modulational dynamics of striped pattern formation in the wake of a directional quenching mechanism. Such mechanisms have been proposed to control pattern-forming systems… Show more Speaker: Ben Krewson, Troy Schneider, Lauryn Williams, Brandon Lee |
|
| Water Ice and Spin Ice: Ground States and Topological Defects |
Our planet is called Earth, but based on the surface composition, perhaps it should have been called Water. Despite the ubiquitous presence on our planet, water's solid form, ice does not readily enter the ground state upon cooling, owing to residual disorder of the… Show more Speaker: Prof. John Cumings, University of Maryland College Park |

|
| Loop extrusion, chromatin crosslinking, and the geometry, topology and mechanics of chromosomes and nuclei |
The chromosomes of eukaryotic cells are based on tremendously long DNA molecules that must be replicated and then physically separated to allow successful cell division. I will discuss what we have learned about chromosome structure from our group's biophysical… Show more Speaker: John F. Marko, Northwestern University |
|
| Exploring anyons and black holes-like dynamics in flatland |
The world and the Universe we live in are composed of fermions and bosons. The quantum statistics of these particles overwhelmingly governs what we see around us. But one could wonder, can other kinds of quantum particles exist? I will begin this colloquium with an… Show more Speaker: Smitha Vishveshwara, UIUC |
|
| Strongly-interacting systems: from fractional quantum Hall effect to field-theoretic dualities |
Quantum systems with strong interaction exist in many branches of physics and present a challenge for theory. We will discuss some recent methods to solve the problem, focusing on one particular example: the fractional quantum Hall fluid. Many phenomena occurring in… Show more Speaker: Prof. Dam Thanh Son, University of Chicago |

| Climatic and Humanitarian Impacts of Nuclear War |
A nuclear war between any two nations, such as India and Pakistan, with each country using 50 Hiroshima-sized atom bombs as airbursts on urban areas, could inject 5 Tg of soot from the resulting fires into the stratosphere, so much smoke that the resulting climate… Show more Speaker: Dr. Alan Robock, Rutgers University |
