Members of the Optical Society, a leading professional organization for those who study the science of light, have elected Prof. Eric Mazur to serve as OSA vice president in 2015. He will serve one year as vice president, followed by one year as president-elect, president in 2017, and past-president in 2018. (Read the Press Release.)

Harvard Physics Research Scientist Vincent Coljee is one of finalists in the international group of 21 volunteers selected for possible participation in Mars Arctic 365 mission by the Mars Society, dedicated to furthering the exploration and settlement of the Red Planet.
Thomson-Reuters Highly Cited Researchers represents some of world’s leading scientific minds. Over three thousand researchers (144 of them in physics) earned the distinction by writing the greatest numbers of reports officially designated by Essential Science Indicators℠ as Highly Cited Papers—ranking among the top 1% most cited for their subject field and year of publication, earning them the mark of exceptional impact.
ΔBz oscillations.: (a) The pulse sequence used to estimate ΔBz. (b) Using nuclear feedback, ΔBz oscillations decay in a coherence time due to residual slow fluctuations in ΔBz. (c) The Ramsey sequence used to operate the S-T*2 ≈ qubit in the rotating frame. (d) The Ramsey contrast (blue dots) decays in a characteristic time (solid line fit ) similar to the oscillations in b due to the same residual slow fluctuations in ΔBz. (e) The Rabi pulse sequence used to drive the qubit in the rotating frame.
The Harvard Physics Teaching Lab is hosting a section of a course taught by Neil Gershenfeld (MIT) and offered jointly at MIT and Harvard, "How to Make (Almost) Anything." The Harvard section is comprised of five women and eleven men from across the campus, including students and staff from Physics, SEAS, GSD, and other departments.
