Physics 298
Speaker: Francois Amet (Stanford University)
The electronic properties of graphene are well described by a non-interacting Dirac Hamiltonian with a fourfold symmetry associated with spin and valley, an additional degree of freedom due to the hexagonal crystal lattice of graphene. As a result, graphene exhibits a variety of peculiar phenomena... Read More »

Physics 128
Speaker: David Weitz (Harvard)
"Dripping, Jetting, Drops and Wetting: The Magic of Microfluidics" This talk will discuss the use of microfluidic devices to precisely control the flow and mixing of fluids to make drops, and will explore a variety of uses of these drops. These drops can be used to create new materials that are... Read More »

Physics 119
Speaker: David Weitz (Harvard University)
The stiffness of cells is commonly assumed to depend on the stiffness of their surrounding: bone cells are much stiffer than neurons, and each exists in surrounding tissue that matches the cell stiffness. In this talk, I will discuss new measurements of cell stiffness, and show that that cell... Read More »

Physics 298
Speaker: Thomas Barthel (Univ. Paris Sud, Orsay, France)
Ultimately, every quantum system of interest is coupled to some form of environment which leads to decoherence. Until our recent study, it was assumed that, as long as the environment is memory-less (i.e. Markovian), the temporal coherence decay is always exponential-- to such a degree that this... Read More »
Monday, April 21, 2014 - 3:00pm
Physics 128
Speaker: Thomas Barthel (Univ of Paris-Sud and CNRS)
** Please note this event is on MONDAY not Wednesday. ** The non-locality of quantum many-body systems, and hence their information content, can be quantified by entanglement measures. For ground states of condensed matter systems, I will discuss how the entanglement scales with the subsystem size... Read More »
Friday, April 18, 2014 - 4:00pm
Bostock Library 023
Speaker: Paul M. Magwene, Department of Biology and Center for Systems Biology
This course, which has as a prerequisite "Introduction to Unix" offered March 24&26 (or equivalent experience), provides an introduction to scientific computing using the Python programming language. The course covers basic data types, data structures, control flow statements, and commonly used... Read More »
Thursday, April 17, 2014 - 11:00am
Physics 278
Speaker: Alexandre Deur (Jefferson Lab)
We will discuss a correlation seen between the dark matter content and the ellipticity of elliptical galaxies. The analysis method for this investigation will be described and the origin of the correlation -whether it is physical or an observational/methodological bias- will be discussed. If of... Read More »
Wednesday, April 16, 2014 - 3:30pm
Physics 128
Speaker: Lisa Manning (Syracuse University)
For important biological functions such as wound healing, embryonic development, and cancer tumorogenesis, cells must initially rearrange and move over relatively large distances, like a liquid. Subsequently, these same tissues must undergo buckling and support shear stresses, like a solid. Our... Read More »

Physics 298
Speaker: Pol Bernard Gossiaux (SUBATECH Nantes)
Discovering a new state of matter is always a major event for the scientific community. As the science moves forward, those new states are always more difficult to discover andand need increasing effort to be understood. The field of nuclear physics does not make exception to this rule: more then... Read More »
Tuesday, April 15, 2014 - 11:30am
Physics 298
Speaker: Sara Haravifard (U. Chicago and Argonne NL)
SrCu2(BO3)2 (SCBO) has corner-sharing Cu2+ spin-1/2 dimers lying on a square lattice, corresponding to the two-dimensional Shastry-Sutherland model. I will present the results of the first single-crystal neutron scattering measurements at high pressure at the Spallation Neutron Source, which... Read More »
