Quantum time talk today

December 12th, 2009

One of the members of my Macintosh programming SIG asked me if for today’s meeting I would talk about Quantum Time, which I was, of course, happy to do.  There is nothing like explaining something to a bunch of intelligent listeners for getting it straight in your own head.  And if you can get across some of the wonder & the weird that is modern physics, that’s even better!

I’ve got the slides online (see under talks).  Summary:

Why quantum time?

Why quantum time?

A few years ago I was looking for an interpretation/formalism for quantum mechanics which would be manifestly symmetric between time and space. The first question I had was:

Is time already quantized?

Is time treated using the same quantum rules as space is? can quantum mechanics be written in a way which is manifestly covariant?

“Quantum time” slightly less fuzzy: clean copy up.

I’d like to thank Ferne Welch and Arthur Tansky for copy-editing the previous version of “Quantum Time“.  It bears a significantly greater resemblance to English now!

And I would like to thank Jonathan Smith and also Mark West and Ashleigh Thomas for help in getting setup at University of Pennsylvania.

If anyone knows a bibtex style that handles electronic references well, please let me know.   If no suggestions, then I think I will warm up learning Old Kingdom hieroglyphs, then tackle bibtex.

All comments on Quantum Time are very welcome.  I’m planning to fold such into the great work of time as appropriate, then, if not too discouraged, push Quantum Time to the archive.

Thanks!

Quantum time – Overview

In relativity time and space are treated symmetrically but in quantum mechanics the treatment of time is very different:  in quantum mechanics time enters as a parameter, not an observable.

In my dissertation, I bridge this gap from the quantum mechanics side by quantizing time using the same rules as for space and then seeing what happens.
