Phymaths podcast # 68 || Dr. Keshav Dasgupta

DescriptionKeshav Dasgupta is a theoretical physicist at McGill University, working on string compactifications, especially on achieving deSitter spacetime from string theory (including the possibility of achieving deSitter as an excited state). The list of his works can be found below.Some links1) His works: https://inspirehep.net/authors/1012406?ui-citation-summary=true2) Link to the high-energy physics resources page on my website: https://hassaansaleem.com/graduate-level-theoretical-physics-resources-in-progress/Contact InfoMy website: hassaansaleem.comFollow on Instagram: https://www.instagram.com/hassaan.3142/Join the WhatsApp channel: https://whatsapp.com/channel/0029Va9DkjmAzNbs7IlGuv1XFollow on Twitter: https://twitter.com/Hassaan_PHYEmail Queries: greatestmight@gmail.comTime stamps(0:00) Coming Up(0:41) Introduction of the guest(0:59) His current projects(15:23) The deSitter problem in string theory (a summary)(26:42) deSitter as an excited state(35:09) Breaking supersymmetry(38:05) Norm of coherent states(39:08) Fluctuations as coherent states(41:28) Why did the 500-page paper become that long?(45:50) Duality sequences(55:16) Non-supersymmetric case?(1:02:30) What are you calculating?(1:07:39) Evading no-go theorems(1:14:09) Worldsheet description available?(1:17:10) Holographic dual of Glauber Sudharshan state(1:18:23) The issue of scale separation(1:21:00) Satisfying swampland constraints(1:24:34) Embedding standard model(1:27:51) Using localization techniques(1:31:22) Open problems(1:36:41) Choosing research problems(1:43:19) Handling multiple projects(1:44:50) (People's question) Comparison with KKLT(1:49:16) (People's question) Writing short papers(1:53:16) Interaction with Ed Witten(1:54:50) (People's question) Living in Montreal
