Dragan Huterer (Univ Michigan) Thu. November 30th, 2017
4:00 pm-5:00 pm

New Views of the Universe
I will discuss how progress in cosmology over the past decade has improved our understanding of dark matter, dark energy, and the physics of the early universe. …Read more.

A.H. Heuer (CWRU Materials Science and Engineering) Thu. November 16th, 2017
4:00 pm-5:00 pm

Mechanism of Aluminum-Oxide Scale Formation on some High-Temperature Structural Alloys
The formation of Al2O3 scale on high-temperature structural alloys is a subject of immense technological importance, as well as of considerable scientific interest. …Read more.

Xuan Gao (CWRU Physics) Thu. November 9th, 2017
4:00 pm-5:00 pm

2D Materials: from Semiconductors to Topological Insulators
Abstract: Since the first isolation of one-atom thick graphene, research on two-dimensional (2D) materials with layered crystal structure has exploded over the past decade. …Read more.

Peter Lu (Harvard University) Thu. October 26th, 2017
4:00 pm-5:00 pm

Gelation of Particles with Short-ranged Attraction
Nanoscale or colloidal particles are exceptionally important in many realms of science and technology. They can dramatically change the properties of materials, imparting solid-like behavior to a wide variety of complex fluids, from yoghurt to cast ceramics. …Read more.

Peter Lu (Harvard University) (Not a Colloquium but of related interest) Wed. October 25th, 2017
5:00 pm-6:00 pm

Lecture co-sponsored by the departments of Physics and Art History, the Baker-Nord Center for the Humanities, and the Cleveland Museum of Art. Note unusual time and venue.
The conventional view holds that geometric star-and-polygon patterns in medieval Islamic architecture were designed using a straightedge and a compass. …Read more.

Jason Alicea (Caltech) Thu. October 19th, 2017
4:00 pm-5:00 pm

Majorana Materializes 
In 1937 Ettore Majorana introduced the concept of what are now fittingly called Majorana fermions — fermionic particles that are their own antiparticles. Nowadays an active search for condensed-matter analogues of these elusive objects is well underway, motivated by both the prospect of revealing new facets of quantum mechanics and longer-term quantum computing applications. …Read more.

No colloquium this week Thu. October 12th, 2017

Indu Satija (George Mason University) Thu. October 5th, 2017
4:00 pm-5:00 pm

Pure & Poetic: Butterfly in the Quantum World
The Hofstadter butterfly is a fascinating two-dimensional spectral landscape – a graph of the allowed energies of an electron in a two-dimensional crystal in a magnetic field. …Read more.

Idit Zehavi (CWRU, Astronomy) Thu. September 28th, 2017
4:00 pm-4:00 pm

Galaxy Clustering and the Galaxy-Halo Connection
In the contemporary view of the Universe, galaxies form and evolve in dark matter halos.  Modern galaxy surveys, most notably the Sloan Digital Sky Survey, have transformed the study of large-scale structure enabling detailed measurements of the spatial distribution of galaxies. …Read more.

Jeremy Levy (Univ Pittsburgh) Thu. September 21st, 2017
4:00 pm-5:00 pm

Correlated Nanoelectronics 
The study of strongly correlated electronic systems and the development of quantum transport in nanoelectronic devices have followed distinct, mostly non-overlapping paths.  Electronic correlations of complex materials lead to emergent properties such as superconductivity, magnetism, and Mott insulator phases.  …Read more.

Liang Wu (Berkeley); Michelson Postdoctoral Prize Lecture Thu. September 14th, 2017
4:00 pm-5:00 pm

Quantized electro-dynamical responses in topological materials
Although solid-state systems are usually considered “dirty” with impurities and imperfections, it is still the case that macroscopic, quantized phenomena can be observed in the form of the Josephson effect in superconductors and the quantum Hall effect in 2DEG. …Read more.

Mike Tamor (Ford Research) Thu. September 7th, 2017
4:00 pm-5:00 pm

History, Geometry and the Future of Mobility
For over a century the personal automobile has served as a highly adaptable transportation tool and an aspirational symbol of wealth and freedom.  …Read more.

Jun Zhu (Penn State) Thu. August 31st, 2017
4:00 pm-5:00 pm

Quantum valley Hall kink states and valleytronics in bilayer graphene
Conventional field effect transistors control current transmission by controlling the charge of carriers. The advent of two-dimensional materials with hexagonal crystal symmetry offers a new electronic degree of freedom, namely valley, the manipulation and detection of which could potentially be exploited to form new many-body ground states as well as new paradigms of electronic applications. …Read more.
