Jammed States of Matter

Almost any system composed of discrete pieces large enough that thermal fluctuations can be ignored can have a jamming transition: a point at which fluid flow is impeded by a change of state into a stable amorphous solid.  The behavior is general enough to explain a pile of sand, a jar of candies, or cars in a traffic jam.  Professor Andrea Liu was involved in recent theoretical breakthroughs in the study of this phenomenon.

 

Dark Excitons

Excitons are electrically neutral excited states of a material consisting of a bound state of an electron and a hole.  Prof. Jay Kikkawa explores previously unseen "dark exciton" states in carbon nanotubes and shows their dependence on geometry of the nanotube.

 

NMDA

Professor Bob Hollebeek was the technical lead for the National Library of Medicine sponsored National Digital Mammography Archive, which provides distributed grid systems for medical storage and records handling.  Parallel and distributed computing approaches apply to the analysis of data from many fields including medical, scientific, social, and economic data.

 

Master of Medical Physics

The Department of Physics and Astronomy in the School of Arts and Sciences, in conjunction with the Departments of Radiology and Radiation Oncology in the School of Medicine, offers the Master of Medical Physics degree. The program is intended for technically prepared college graduates who seek to combine their interests in graduate physics with growing career opportunities in the field of medicine.

 

CNT Transistor with Antibodies

Prof. Charlie Johnson's lab has produced new experiments demonstrating that carbon nanotube transistors (CNT) can detect minute quantities of biomarkers of diseases in less time than conventional methods.  Antibodies attached to 
CNT on a silicon chip change the electrical properties of the chip upon antibody-antigen binding hence detecting disease biomarkers.
