Department of Physics and Astronomy, San Francisco State University Roger Bland recently coauthored a paper that explores the destruction of superconductivity in Yttrium barium copper oxide (YBa2Cu3O7). This material was the first to be known to achieve superconductivity above the boiling point of nitrogen. Dr. Bland's paper, published in the Journal of Low Temperature Physics, studi...es the time evolution of phase-slip centers and hot spots in a superconducting YBa2Cu3O7 strips using pulsed techniques. The behavior of these dissipative centers is found to be similar to that of superconducting niobium strips, at helium temperatures. Better understanding of the behavior of high-temperature superconductors at high current densities should contribute to their applications in high-field magnets.

See MoreDepartment of Physics and Astronomy, San Francisco State University Joseph Barranco's recent paper in the Astrophysical Journal sheds new light on the physics of stellar interiors. Together with colleagues at Harvard University, Dr. Barranco explores the turbelent conditions inside the convective (or "boiling") regions below the surface of most stars. Their calculations of the effectiv...e viscosity are highly relevant for predicting the properties of pulsating stars such as Cepheid variables.

The current understanding of the turbulent dissipation in stellar convective zones is based on the assumption that the turbulence follows Kolmogorov scaling. This assumption is valid for some cases in which the time frequency of the external shear is high (e.g., solar p modes). ...
Department of Physics and Astronomy, San Francisco State University Roger Bland's research on underwater acoustics was recently featured on KCBS radio. A low hum reminiscent of a leaf blower or lawnmower seems to be coming from the waters off Tiburon and Sausalito. Dr. Bland was contacted by KCBS, and offered the explanation featured in the link below (a brief ad precedes the actual report).

Department of Physics and Astronomy, San Francisco State University Maarten Golterman recently delivered a series of lectures on chiral perturbation theory at the prestigious Les Houches summer school of physics in the French Alps. The school has hosted workshops for research in theoretical physics since 1951...; several of the graduates (and teachers) have gone on to become Nobel laureates.

The purpose of the School is to impart a deeper theoretical understanding of lattice QCD as well as to survey new, powerful computational methods. Our principal aim is to bring a new generation of young theorists into contact with leading experts in these fields. ...
Department of Physics and Astronomy, San Francisco State University Zhigang Chen has won a new $370K grant from the Air Force Office of Scientific Research. This tops off a summer where he was honored as a newly elected fellow by the Optical Society of America, and published articles in Optics Letters and Optics Express.

Department of Physics and Astronomy, San Francisco State University The department's annual GRE review course will begin soon. Seniors and graduate students are strongly encouraged to take advantage of this opportunity to prepare for the Physics GRE. The first organizational meeting for the course will be at 5:00PM on Tuesday, September 1, in Thornton 230.
Department of Physics and Astronomy, San Francisco State University Our first department-wide meeting will be at 4:00PM on Monday, August 31st, 2009, in Thornton 411. All students and faculty should attend this meeting. Also, if you are having trouble signing up for upper level courses (numbered 300+), please show up for class on the first day anyway. We'll get the registration issues ...sorted out. Unfortunately, seats in lower-level courses (numbered 100-299) are likely to be scarce.
