An interview with Nobel laureate Roy Glauber, Physics 2005


JoVE 1535

The field of quantum optics rests on the work of Roy Glauber, who helped elucidate the nature of light as both particles and waves. In this candid interview, the Nobel prize-winning physicist shares his thoughts about this strange and unintuitive behavior of light, balancing fatherhood with an academic career, and working at Los Alamos National Laboratory, where he shockingly learned that he was helping to build The Bomb.

An Interview with Nobel Laureate Theodor Hansch, Physics 2005


JoVE 1537

Theodor Hänsch was a co-recipient of the 2005 Nobel Prize in Physics for "contributions to the development of laser-based precision spectroscopy, including the optical frequency comb." In this video, Hänsch explains "in a nutshell" the frequency comb, its theories, its many applications, and the breakneck pace of the research leading up to the Nobel Prize.

An Interview with Nobel Laureate Douglas Osheroff, Physics 1996


JoVE 1540

At extremely low temperatures, the molecules of certain fluids are able to flow without internal friction or resistance - a phenomenon know as superfluidity. In this interview, Nobel Laureate Douglas Osheroff (Physics 1996) describes the somewhat arduous quest to prove the predicted superfluid state of helium-3. He also shares his thoughts on mentoring undergraduates and his philosophy on getting the most out of graduate school.

Setting Limits on Supersymmetry Using Simplified Models

1Department of Physics and Astronomy, University College London, 2CERN, 3Physics Division, Lawrence Berkeley National Laboratories


JoVE 50419

This paper demonstrates a protocol for recasting experimental simplified model limits into conservative and aggressive limits on an arbitrary new physics model. Publicly available LHC experimental results can be recast in this manner into limits on almost any new physics model with a supersymmetry-like signature.

Sputter Growth and Characterization of Metamagnetic B2-ordered FeRh Epilayers

1School of Physics and Astronomy, University of Leeds, 2Institute of Materials Research, University of Leeds, 3School of Chemistry, University of Edinburgh, 4Department of Chemical Engineering, Northeastern University, 5Department of Physics, Northeastern University


JoVE 50603

A method to prepare epitaxial layers of ordered alloys by sputtering is described. The B2-ordered FeRh compound is used as an example, as it displays a metamagnetic transition that depends sensitively on the degree of chemical order and the exact composition of the alloy.

Spatial Separation of Molecular Conformers and Clusters

1Center for Free-Electron Laser Science, CFEL, DESY, 2Department of Physics, University of Hamburg, 3The Hamburg Center for Ultrafast Imaging, University of Hamburg


JoVE 51137

We present a technique that allows the spatial separation of different conformers or clusters present in a molecular beam. An electrostatic deflector is used to separate species by their mass-to-dipole moment ratio, leading to the production of gas-phase ensembles of a single conformer or cluster stoichiometry.

Scanning-probe Single-electron Capacitance Spectroscopy

1Department of Physics and Astronomy, Michigan State University, 2Department of Chemistry & Biochemistry/Physics, Mercyhurst University, 3Department of Physics, Saint Louis University, 4Department of Physics, Massachusetts Institute of Technology


JoVE 50676

Scanning-probe single-electron capacitance spectroscopy facilitates the study of single-electron motion in localized subsurface regions. A sensitive charge-detection circuit is incorporated into a cryogenic scanning probe microscope to investigate small systems of dopant atoms beneath the surface of semiconductor samples.

Synthesis and Operation of Fluorescent-core Microcavities for Refractometric Sensing

1Department of Physics, University of Alberta


JoVE 50256

Fluorescent-core microcavity sensors employ a high-index quantum-dot coating in the channel of silica microcapillaries. Changes in the refractive index of fluids pumped into the capillary channel cause shifts in the microcavity fluorescence spectrum that can be used to analyze the channel medium.

The Generation of Higher-order Laguerre-Gauss Optical Beams for High-precision Interferometry

1School of Physics and Astronomy, University of Birmingham


JoVE 50564

Large laser-interferometers are being constructed to create a new type of astronomy based on gravitational waves. Their sensitivities, as for many other high-precision experiments, are approaching fundamental noise limits such as the atomic vibration of their components. We are pioneering technologies to overcome these limits using novel laser beam shapes.

Visualizing Protein-DNA Interactions in Live Bacterial Cells Using Photoactivated Single-molecule Tracking

1Microbiology Unit, Department of Biochemistry, University of Oxford, 2Biological Physics Research Group, Clarendon Laboratory, Department of Physics, University of Oxford


JoVE 51177

Photoactivated localization microscopy (PALM) combined with single-molecule tracking allows direct observation and quantification of protein-DNA interactions in live Escherichia coli cells.
