Junior and senior physics majors attend our biweekly colloquium series, held on Tuesday afternoons at 4:30 pm in Shanahan B460. The talks are open to all students and to the public, and are frequently attended by scientists from the other Claremont Colleges, Cal Poly Pomona, and others. The series features speakers from a broad range of institutions and fields of physics.

Dances With Atoms and Photons: Steps Toward Quantum Information Technology
The Schrödinger-cat strangeness of quantum states threatens classical information technology but at the same time offers the potential for great advances in computing and communications. A principal challenge in designing actual quantum logic devices is the need to control quantum states and simultaneously protect delicate properties like quantum phase and entanglement. How can we protect information encoded in a quantum ...

National Academy Study on the Comprehensive Nuclear Test Ban Treaty
After the 51-48 defeat of the CTBT in the Senate, General John Schalikashvili (Former Chair, Joint Chiefs of Staff) commissioned the National Academy of Sciences to examine the following technical issues, which will be summarized*:
  • US Capacity to maintain safety/reliability and design/evaluation of its nuclear stockpile without testing
  • International/US capability to monitor a nuclear test ban, ...

Black Holes and Extra Dimensions
Of the four known forces -- gravity, electromagnetism, and the weak and strong forces -- gravity is by far the weakest. The weakness of gravity may not be an intrinsic property, however, but may result from the dilution of gravity in extra spatial dimensions. Diverse experiments, ranging from tabletop probes of Newtonian gravity to km-scale cosmic ray detectors, are now ...

Heating up the Vacuum: a New Spin on QCD at RHIC
Why are the proton’s constituents confined? Where does its mass come from? What makes up its spin? The theory of the strong force, QCD, has proven strikingly successful (e.g. this year’s Nobel Prize), however, so far it cannot be used to understand these fundamental questions. We have begun an experimental program at Brookhaven National Laboratory utilizing the Relativistic Heavy Ion ...

Bits of the Future: Magnetic Recording Beyond the Superparamagnetic Limit
Storage densities of magnetic recording systems are currently doubling every year in both laboratory demonstrations and hard disk drive products. Increasing the storage density has mainly been achieved by scaling the head and media parameters to smaller dimensions. However, as many of the critical dimensions approach the nanometer scale, a variety of physical phenomena are predicted to limit the capacity ...

Quantum Computation: Why, What, and How
The traditional view of quantum mechanics as restricting what can be done classically has been turned upside down by quantum information science, which explores how coherent quantum-mechanical information processing can be used to accomplish tasks that would be impossible in a classical world. Implementing quantum information processing protocols promises to be one of the enduring scientific and technological challenges of ...
