Physics Colloquia Series Presents: Dr. Trevor Cross,Group Chief Technology Officer, e2v, entitled '60 years of imaging technology'

From the earliest commercial production of electronic image sensors for television in the 1950s, to the diverse application of specialist silicon image sensors for the Hubble space Telescope to digital dentistry this talk will outline the manufacturing technology and changes through 60 years at e2v. Somewhat surprisingly, there are today lessons to be learned, and technologies to be applied from this to the emerging new platform technology of ultra-cold atom sensing and metrology.

Physics Colloquia Series Presents: Dr Cait McPhee, University of Edinburgh, entitled 'Proteins as switchable Janus ellipsoids'

Janus particles are micro- or nano-scale particles whose surfaces have two or more distinct physical properties. Such asymmetry results in interesting self-assembly properties, but homogeneous Janus particles can be difficult to synthesize. The protein BslA (Bacterial Surface Layer A) is a small (~4 nm) protein produced by the bacterium Bacillus subtilis that has a hydrophilic ‘body’ to which is appended a surface-exposed hydrophobic ‘cap’.

Physics Colloquia Series Presents: Professor Séamus Davis, Cornell University, entitled 'Visualizing Quantum Matter'

Everything around us, everything each of us has ever experienced, and virtually everything underpinning our technological society and economy is governed by quantum mechanics. Yet this most fundamental physical theory of nature often feels as if it is a set of somewhat eerie and counterintuitive ideas of no direct relevance to our lives. Why is this?

Physics Colloquia Series Presents: LIGO Special by Professor Gabriela Gonzalez entitled 'Searching for - and finding! Gravitational Waves'

On September 14 2015, the two LIGO gravitational wave detectors in Hanford, Washington and Livingston, Louisiana registered a nearly simultaneous signal with time-frequency properties consistent with gravitational-wave emission by the merger of two massive compact objects. Further analysis of the signals by the LIGO Scientific Collaboration and the Virgo Collaboration revealed that the gravitational waves detected by LIGO came from the merger of a binary black hole system. This observation, followed by another one in December 2015, marked the beginning of gravitational wave astronomy.

Colloquia Series Hilary Term 2017

The following lectures will be given at 3.30pm on Fridays in the Martin Wood Lecture Theatre, Clarendon Laboratory, Parks Road (unless otherwise stated). Tea will be served in the Physics Common Room at 4.30 pm.

The aim of the colloquia series is to share with members of the department the latest information on physics research and developments. Undergraduates, graduates, postdocs, faculty members and support staff are all encouraged to attend these lectures.

LSST-DESC meeting July 18-22, 2016

One hundred and fifty members of the Dark Energy Science Collaboration (DESC) of the Large Synoptic Survey Telescope (LSST) Collaboration held their annual summer meeting in Oxford in July, 2016 co-hosted by the Sub-departments of Astrophysics and Particle Physics. This was the first time LSST-DESC had held a meeting outside the U.S.

Supersymmetry squeezed at the high-energy frontier

First year Oxford graduate student Jesse Liu has just released a paper showing how the increase in LHC energy from 8 to 13 TeV has squeezed the permissible models of the theory of supersymmetry.

Supersymmetric theories predicts particles that could help explain the mysterious dark matter in our universe, and which can be produced at the LHC, so they are well worth pursuing.

Colloquia Series Trinity Term 2016: Lobanov- Rostovsky Lecture - Professor Raymond Pierrehumbert - “The origins and evolution of exoplanet astmospheres and oceans”

Date: 
27 May 2016 (All day)
Venue: 
clarendon
Room: 
Martin Wood Lecture Theatre

Atmospheres are dynamic entities, formed from the volatile substances that accrete when a planet is formed and later in its history, cooked out in the hot-high pressure interior of the planet, and exchanging with the interior through crustal processes (for planets which have a solid surface) or mixing into the deep interior (for fluid planets). Loss of atmosphere to space is also a major mechanism whereby the chemical composition of entire planets evolve.

Colloquia Series Trinity Term 2016: Professor Bruce Remington - “Frontier Science on the National Ignition Facility (NIF)”

Date:

Venue:

Room: 
Martin Wood Lecture Theatre

The combination of high energy density (HED) facilities around the world spanning microjoules to megajoules, with time scales ranging from femtoseconds to microseconds, enables new regimes of plasma science to be experimentally probed. The ability to shock and ramp compress samples at Mbar pressures and simultaneously probe them allows dense, strongly coupled, Fermi degenerate plasmas relevant to planetary interiors, as well as solid-state lattice dynamics and plastic flows, to be studied.
