The Department of Physics at City College has a long tradition of distinguished faculty and students. Many of our alumni have achieved prominence in academic, industrial and governmental physics positions; three of them, Arno Penzias, Leon Lederman and Robert Hofstadter, have won the Nobel Prize in Physics.
Today the Department continues to reflect this tradition of scientific excellence. The faculty include members of the National Academies of Sciences and National Academy of Engineering, fellows of the American Physical Society, and the American Academy of Arts and Sciences. They are deeply engaged in cutting-edge research, including biophysics, high-energy physics, condensed matter and soft-condensed matter physics, ultrafast spectroscopy and photonics, to name just a few.

Two Must-attend Events!
Lecture by Nobelist Chu to Span Micro and Macro
Two diverse topics—the impact of new imaging technologies on biology and medicine, and the transition to a sustainable world—will be discussed by Nobel Laureate in Physics and former Energy Secretary Steven Chu at CCNY's Herman Cummins Lecture on April 17.
Myriam Sarachik is Distinguished Professor of Physics at The City College of New York. On Thursday, April 23, she speaks of her past experiences and her life-long advocacy for women in science and the human rights of scientists everywhere in the final talk of City College’s inaugural “Presidential Conversations: Activism, Scholarship, and Engagement” series.Her topic, 4 – 5: 30 p.m. in CCNY’s NAC Ballroom, is entitled “Advocating for Women in Science: Advocating for the Human Rights of all Scientists.”
Two Alumni win American Physical Society Awards
Robert J. La Haye, General Atomics
Robert J. La Haye received his B.S. and M.S. in physics from Queens College, and his Ph.D. in physics from the City University of New York in 1975. La Haye has taken many assignments abroad. For instance, he has taken part in thin-shell reversed field pinch stability experiments on the High Beta Toroidal Experiment 1C device at the Culham Center for Fusion Energy, in error-field experiments on both the COMPact ASSembly and Joint European Torus (JET) tokamaks, and in long-pulse beta limit experiments, dominated by neoclassical tearing modes on JET. He is currently the principal investigator for the General Atomics grant in support of research on the National Spherical Torus Experiment at the Princeton Plasma Physics Laboratory. La Haye is a fellow of the American Physical Society.
2015 Joseph F. Keithley Award for Advances in Measurement Science
Robert J. Celotta, National Institute of Standards and Technology
Robert J. Celotta received his B.S. in physics from the City College of New York in 1964 and his Ph.D. in physics from New York University in 1969. He was a postdoctoral fellow at JILA in Boulder, Colorado. He joined the National Institute for Standards and Technology (NIST), became a NIST fellow, led the Electron Physics Group, and now directs the Center for Nanoscale Science and Technology. HIs most recent research activities included nanomagnetics, magnetic imaging, the use of scanning tunneling microscopy for nanostructure characterization and assembly, the optical control of free atoms, and the generation, detection and application of free-electron polarization to measurement. He is a fellow of APS, AAAS and AVS.

One promising method to diagnose cancerous tissue without removing tissue is based on optical spectroscopy. Optical Biopsy is becoming commonplace to determine the state of tissue in vivo and ex viva. The major focus in Optical Biopsy is to measure native fluorescence to characterize the properties of normal, benign and malignant metastasic cancers. Key intrinsic molecules in cells and tissues have unique spectral profiles for absorption and emission from the ultraviolet to visible range. The emission from tryptophan is clearly the main fluorescence over the other molecules upon exciting the tissues and cells. Tryptophan is the "food" not only for cancer cells but also for immune cells; the more cancer cells consume, the less is left for immune cells. Starvation of the immune cells causes apoptosis. The immune system fails to detect the cancer cells and the cancer cells can spread easily.
The invention teaches that tryptophan level is an important biomarker for determining aggressive cancers in cells. Native fluorescence spectroscopy is used as an effective approach to distinguish cancer cell lines with different metastatic ability as well as normal cell lines, based on their tryptophen levels.

Scientific research is dramatically more global in its practice and impact than it was just a decade ago. Whether the United States is able to capitalize effectively on new discoveries stemming from international collaborations will determine future economic growth and job creation in America. More...

New Half-Light Half-Matter Quantum Particles
Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward thanks to research by City College of New York physicists led byDr. Vinod Menon. Professor Menon’s research team included City College PhD students, Xiaoze Liu, Tal Galfsky and Zheng Sun, and scientists from Yale University, National Tsing Hua University (Taiwan) and Ecole Polytechnic -Montreal (Canada). The study appears in the January issue of the journal “Nature Photonics.” It was funded by the U.S. Army Research Laboratory's Army Research Office and the National Science Foundation through the Materials Research Science and Engineering Center – Center for Photonic and Multiscale Nanomaterials.

The newest edition of the CCNY Physics Department Newsletter is now available.
This year's Nobel Laureates are rewarded for having invented a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources.
