Fire restoration work is expected to continue into late August. The main stairwell and office wing on both second and third floors of the Physics building will be closed until necessary repairs to the main stairwell are completed.
Administrative offices have been relocated to PHY 345.
Please contact individual faculty members to request appointments, as many faculty have been relocated during this process.
Please do not cross any caution tapes whilst in the building.

Dr. Radzihovsky's research interests span a broad spectrum of condensed matter, ranging from liquid crystals, colloids, membranes, rubber and other "soft" matter to degenerate atomic gases, superconductors, and quantum Hall systems.
Refreshments in PHY 313 starting at 3:30 pm
I will discuss a role of quantum indistinguishability in chemical bond-breaking processes. Specifically, I will argue that chemical reactions involving small symmetric molecules require a full quantum treatment of collective nuclear degrees of freedom beyond the conventional Born-Oppenheimer description. I will present physical arguments for a “Quantum Dynamical Selection” (QDS) conjecture that precludes processes that involve direct transitions from orbitally non-symmetric molecular states. QDS leads to a number of striking experimental predictions, such as e.g., a differential chemical reactivity of para- and ortho-hydrogen, a mechanism for inducing inter-molecular quantum entanglement of nuclear spins, and a new mass-independent isotope fractionation mechanism, among others.
