Good web sites support user feedback and discussion forums.
So if you have any questions, feel free to email me at
dr.paul.kinsler@physics.org.
As for discussion forums, I'll just point out my favourite ones: firstly,
the sci.physics.* internet newsgroups (which naturally have a
FAQ file).
I read the newsgroups sci.physics.
research,
electromag,
condmatter,
and
sci.optics.
Secondly, there is the realtime chat medium of IRC (channel
#physics).
As a rule I check the RSS feeds from various
APS, AIP, IoP, and OSA journals,
also the arXiv.
If something catches my eye I might tag it
(rss),
or even blog about it
at citeulike.

Causality editors and blowing bubbles in spacetime
(short intro)

The Maxwell's Fishpond: tabletop transformation aquatics in action! (short intro with video)(blog)

A straightforward treatment of causality in time and spacetime,
including the Kramers Kronig relations

The spacetime cloak, aka the event cloak (chicken analogy)(blog)

Derived and compared four Poynting theorems (one of which is new)

Enhanced my EM pulse propagation methods by applying only minimal approximations

Proposed a new definition for the wavevector that behaves better under loss

Causalitybased constraints on
negative refraction and perfect imaging.
Under (rather slow) construction.
My current area of interest is the propagation of fewcycle optical pulses.
Such ultrashort pulses
have applications in areas ranging from precision spectroscopy
(THz to VUV), optical atomic clocks, and fundamental tests of
physical theories.

Developed theory of propagation of directed EM fields, allowing
nearexact pulse envelope propagation;

Developed the most general form of standard envelope theory based on
the second order wave equation, for propagation of
(fewcycle) optical pulses;

Theory for ultrawideband nonlinear optical processes (e.g.
parametric amplifiers, Raman).

are
typically between a nanometre and a micrometre in size.
They are made by processes similar to those used to make
integrated circuits (computer chips). The structures can
control where and how electrons and photons can move and
affect each other on a quantum level. In particular I
investigated the physics behind the future design of
solid state terahertz emitters.

ElectronPhonon Scattering(Sheffield, Leeds).
Quantum optics is the study of the interaction of light (the EM
field) with matter. It covers quantised light interacting with bulk
matter, semiclassical light interacting with quantised atoms,
and quantised light interacting with quantised matter. This is
the field which has given us lasers, optical solitons, squeezing,
and spawned quantum cryptography, quantum computers, and atom optics.

Found analytic solution for the above and below threshold parametric
oscillator, and subsequent demonstration of order of magnitude
differences between quantum and semiclassical tunnelling rates;

Found the first ever solution to a nonequilibrium quantum system at
threshold, with subsequent implications for the testing of quantum
mechanics.
