closed loop of classical string
Actually, there is a good treatment of this in Zwiebach's string theory book. Just check out the earlier chapters, and forget about trying to quantize the string.
Basically, you take the wave equation for a non-closed string, and give it periodic boundary conditions, that's all. | {"url":"http://www.physicsforums.com/showthread.php?t=421552","timestamp":"2014-04-18T10:47:16Z","content_type":null,"content_length":"24081","record_id":"<urn:uuid:416b3c60-3532-434b-af4e-769d3f3fc836>","cc-path":"CC-MAIN-2014-15/segments/1398223206120.9/warc/CC-MAIN-20140423032006-00539-ip-10-147-4-33.ec2.internal.wa... |
