Squeezing Light Cools Microscopic Drum Below Quantum Limit
GAITHERSBURG, Md., Jan. 16, 2017 — Using a special circuit to generate microwave photons stripped of intensity fluctuations, physicists at the National Institute of Standards and Technology (NIST) have cooled a mechanical object to a temperature lower than previously thought possible. The new NIST theory and experiments showed that a microscopic mechanical drum — a vibrating aluminum membrane — could be cooled to less than one-fifth of a single quantum, or packet of energy. John Teufel, NIST physicist said
Thermal Capacity of Photon Gas Measured, Aligns with Theory
BONN, Germany, April 27, 2016 — A method for measuring the thermal capacity of Bose-Einstein photon condensates could enable the development of ultraprecise thermometers. The drop in the heat-storage capacity of liquid water as it changes phase to gas or solid is well understood,...
Remembering a Giant
Mar 1, 2015 — Dr. Charles Hard Townes died Jan. 27 at age 99, and in the weeks since, he has been remembered for his many contributions to physics, to the birth of the laser and for pioneering its use in astronomy. Townes won the 1964 Nobel Prize in physics for...
Novel Laser Could Transmit Quantum Data
HANOVER, N.H., July 23, 2014 — A laser made from a superconducting artificial atom could aid information transfer in quantum computing. To create the laser, a team from Dartmouth College embedded a pair of electrons called a Cooper pair in a high-quality microwave cavity. As...
'Air Waveguides' Function Like Optical Fibers
COLLEGE PARK, Md., July 22, 2014 — A new technique could allow scientists to run optical fiber to nearly any place on earth — and possibly even into space. A team from the University of Maryland has discovered how to make air behave like optical fiber, guiding light beams over...
Optical Invisibility Cloak Ideal for Diffusive Media
KARLSRUHE, Germany, June 9, 2014 — A new invisibility cloak technology conceals objects in diffusive media such as fog, clouds or frosted glass. Optical cloaks have been challenging to achieve for all situations; most only work at specific colors or polarizations, or from very...
Harmonic Generation Promising for Powerful Light Source
MANHATTAN, Kan., June 6, 2014 — A new approach to harmonic generation aims to create smaller, more powerful tabletop light sources for laboratory research, particularly in the emerging area of strong-field physics. “High-order harmonic generation has been considered a very...
New Switch Could Scale Up Quantum Computing
CAMBRIDGE, Mass., April 11, 2014 — A new technique to connect particles could assist in development of quantum computing systems.
3-D AFM Could Advance Understanding of Proteins
COLUMBIA, Mo., Jan. 24, 2014 — An advanced 3-D force microscope will allow the study of membrane proteins in conditions similar to those found in the body, an improvement that could lead to increased understanding of proteins on the microscopic level and faster drug therapies.
Mordechai Segev Awarded Israel Prize
HAIFA, Israel, Jan. 24, 2014 — Physicist Mordechai Segev has been awarded the Israel Prize for his work in the field of optics and lasers.
Laser Components Hires New Head of Optics Production
OLCHING, Germany, Jan. 16, 2014 — Laser Components GmbH has appointed Uwe Schallenberg as its new head of production for the optical technologies department. Schallenberg will lead feasibility studies for new designs and evaluations of optical and technical requirements, as well as...
‘God particle’ theorists share physics Nobel
STOCKHOLM – Peter Higgs and François Englert will share the 2013 Nobel Prize in physics for their independent theoretical discoveries nearly 50 years ago of the Higgs boson, the so-called “God particle” that gives all other particles their...
Quantum Optics Research Garners APS Award
WASHINGTON, Oct. 18, 2013 — A recent physics graduate from the Rochester Institute of Technology has received an award from the American Physical Society (APS) for his quantum optics research. Hao Shi, a native of China, is a 2013 graduate of RIT’s physics program and is...

BERKELEY, Calif., Nov. 21, 2012 — Stuart Freedman, an investigator of fundamental physical laws and a nuclear physicist with Lawrence Berkeley National Laboratory and the University of California, Berkeley, died unexpectedly Nov. 9 while attending a conference in Santa Fe, N.M. He...
Matsuura Named OSA Senior Science Adviser
WASHINGTON, Nov. 6, 2012 — Anne Matsuura, former chief executive of the European Theoretical Spectroscopy Facility (ETSF) in Belgium, has been named senior science adviser at The Optical Society (OSA), the organization announced Monday.
Physics Billboard 'Enlightens' Travelers
LONDON, Nov. 6, 2012 — A vital but little-known physics equation that has led to much of the technological development of the modern world is piquing the curiosity of travelers as they make their way through West London.
Study Finds 1 Million UK Jobs Depend on Physics
LONDON, Oct. 22, 2012 — Four percent of employees in the UK — more than 1 million people — work in physics-based businesses, a sector that could recreate the nation’s economy, according to a recent study by the Institute of Physics.
Reader Poll: School & Major
Aug 1, 2012 — University programs with “photonics” in their names are a rather new development – a reflection of the growing importance of photonics not only to science but to the world – so we decided to poll our readers and find out what...
Search for Higgs Boson at LHC Reveals New Particle
GENEVA, July 5, 2012 — Two Large Hadron Collider (LHC) experiments presented preliminary results Wednesday that describe a new particle consistent with the long-sought Higgs boson, the famous missing ingredient in the Standard Model of particle physics. The findings could...
Frequency Combs Advance Biomedicine
DENVER, June 15, 2012 — Laser frequency combs, first a curiosity but now a practical research tool, are moving beyond physics and optics to advance biomedicine by helping evalulate a novel instrument that kills harmful bacteria without liquid chemicals or high...
StellarNet Launches Spectrometry Contest
TAMPA, Fla., Oct 4, 2011 — Are you an academic researcher with an exciting new project involving spectroscopy, and do you need a free spectrometer system to help achieve this? StellarNet Inc. has launched its STAR Instrument Program, which aims to provide annually a complete...
Photons vs. Protons in Radiation Therapy
COLUMBUS, Ohio, Jan. 13, 2011 — A study comparing the long-term outcomes of patients with spinal-cord tumors after radiation therapy suggests that certain subsets of patients have better long-term survival. It also suggests that photon-based radiation therapy may result in better...
