Pavel Fileviez Perez (CWRU Physics) Thu. December 8th, 2016
4:00 pm-5:00 pm

New Physics and Unification of Forces
The unification of fundamental forces in nature is one of the most appealing ideas for physics beyond the Standard Model of particle physics. …Read more.

Mike Hinczewski (CWRU Physics) Thu. December 1st, 2016

Robert Owen (Oberlin College) Thu. November 17th, 2016
4:00 pm-4:00 pm

Numerical Relativity and Gravitational Radiation from Binary Black Hole Mergers
In September of 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) made the first-ever direct detection of gravitational waves, propagating ripples in the structure of spacetime itself, confirming a nearly century-old prediction of Einstein’s general relativity, and providing an entirely new medium for astronomical observations. …Read more.

Marija Drndic (University of Pennsylvania) Thu. November 10th, 2016
4:00 pm-5:00 pm

2D Materials Nanosculpting and Bioelectronics Applications
Electron beams constitute powerful tools to shape materials with atomic resolution inside a transmission electron microscope (TEM). I will describe experiments where we push the limits of device size to atomic scale in 2D materials beyond graphene (MoS2, WS2, MoTe2, black phosphorous) and expand their function and precision, while addressing fundamental questions about structure and properties at nanometer and atomic scales. …Read more.

Tao Han (University of Pittsburgh) Thu. November 3rd, 2016
4:00 pm-5:00 pm

Physics Motivations for Future Colliders

With the milestone discovery of the Higgs boson at the CERN LHC, high energy physics has entered a new era. The Higgs boson is the last member in the “Standard Model” (SM) of particle physics, which describes the physical phenomena at high energies to a very high accuracy. …Read more.

Andrew Rappe (University of Pennsylvania) Thu. October 27th, 2016
4:00 pm-5:00 pm

Slush Structure and Dynamics in a Relaxor Ferroelectric
Ferroelectric materials undergo solid-solid structural phase transitions between phases with aligned dipoles and randomly oriented dipoles. Incorporating quenched Coulombic disorder by varying the charge of the ions on the lattice disrupts and changes the of this transition; instead of a sharp transition in a small temperature range, these oxide alloys exhibit “relaxed” transition over 100-200 K and are called “relaxor ferroelectrics.” In this talk I will describe how a first-principles based multi-scale model can reveal the dynamic and statically correlated motions of ions that lead to relaxor behavior, and I will discuss their promise for next-generation piezoelectric and dielectric material systems. …Read more.

Jim Van Orman (CWRU EEES) Thu. October 20th, 2016
4:00 pm-5:00 pm

Simulating Planetary Interiors in the Lab
This talk will provide an overview of experimental studies on the properties of planetary materials at high pressures, and the constraints they provide on the structure and evolution of planetary interiors. …Read more.

Mark Newman (University of Michigan) Thu. October 13th, 2016
4:00 pm-5:00 pm

Paul Erdos, Kevin Bacon, and the Six Degrees of Separation: The Statistical Physics of Networks
There are networks in every part of our lives: the Internet, the power grid, the road network, networks of friendship or acquaintance, ecological networks, biochemical networks, and many others.  …Read more.

John Monnier (University of Michigan) Thu. September 29th, 2016
4:00 pm-5:00 pm

Imaging the Surfaces of Stars
Under even the best atmospheric conditions, telescope diffraction fundamentally limits the angular resolution for astronomical imaging. Using interferometry (Go, Michelson!), we can coherently combine light from widely-separated telescopes to overcome the single-telescope diffraction limit to boost our imaging resolution by orders of magnitude. …Read more.

Kurt Hinterbichler (CWRU Physics) Thu. September 22nd, 2016
4:00 pm-5:00 pm

Massive Gravitons, the Cosmological Constant and New Directions in Gravity
The solution to the cosmological constant problem may involve modifying the very long-range dynamics of gravity by adding new degrees of freedom. …Read more.

Director: Peter Galison (Harvard). Movie. Note unusual end time. Thu. September 15th, 2016
4:00 pm-5:30 pm

Can we contain some of the deadliest and most long-lasting substances ever produced? Left over from the Cold War are a hundred million gallons of highly radioactive sludge, thousands of acres of radioactive land, tens of thousands of unused hot buildings, all above slowly spreading deltas of contaminated ground water. …Read more.

Richard Schaller (Northwestern University). Not a physics colloquium but of potential interest to physicists. Note unusual location and time. Thu. September 8th, 2016
4:00 pm-6:00 pm

Chemistry Colloquium: Electronic and Thermal Interconversion and Migration in Energy-Relevant Materials
In order to produce energy efficient devices, thorough understanding of fundamental desired and undesired processes of energy and heat interconversion and migration are needed. …Read more.
