Papers in Loop Gravity and related research lines are coming out at an increasing rate. I've found this boolean search method useful at arxiv. It is a way of keeping up that takes less time since it combines the key words and phrases in a single search(adsbygoogle = window.adsbygoogle || []).push({});

By searching arxiv with the same Boolean expression for 5 years:

2000, 2001, 2002, 2003, and LTM, the last 12 months,

(EDIT: As of March 2, 2004)I got these annual figures

So this is a quick method not to miss new papers in Quantum Gravity and also one possible way to gauge the growing energy in the field.Code (Text):

year number of papers

2000 80

2001 86

2002 111

2003 123

LTM 132

This Boolean expression fits into the arxiv search form and turns up papers in:

loop quantum gravity

spin foam

loop quantum cosmology

canonical quantum gravity

discrete quantum gravity

doubly special relativity

quantum gravity phenomenology

Here's how to enter it

1. go to the archiv search form

http://arxiv.org.

http://arxiv.org./multi?group=physics&/find=Search

2. change author and title fields to "abstract"

and the two ANDs over at the righthand side to OR

3. all three keyword fields are now directed to search

the paper's abstract, fill them in as follows

(loop AND quantum) AND (gravity OR cosmology)

(quantum AND gravity) AND ((phenomenology OR canonical) OR discrete)

(spin AND foam) OR (doubly AND special)

4. check the box that says "search all" and select the desired year

5. press "do search"

------------------------------

your browser will probably "remember" how you filled the keyword blanks out before. So having done it once, you will afterwards just have to type the first character(s), and the rest will be supplied.
