Cosmological Correlators in Taiwan

Asia/Taipei
Chee-Chun Leung Cosmology Hall No. 1, Sec. 4, Roosevelt Rd. Taipei 10617, Taiwan
Description

This is the third in a series of workshops on cosmological correlators (broadly defined). The first two workshops were held in Cambridge (online) and Cortona (in-person). 

The workshop will bring together international experts on topics including quantum field theory in curved spacetime, cosmological correlators, inflation, quantum aspect of de Sitter spacetime, bootstrap techniques, quantum gravity and holography. The goal is to critically review recent progress, generate novel and concrete ideas and foster new collaborations. To this end, the format of this 5-day workshop will feature three or four talks per day followed by organized as well as spontaneous discussions.

The workshop is followed by the conference "QCD Meets Gravity".

 

Organizers:

  • Daniel Baumann (NTU)
  • Enrico Pajer (Cambridge)
  • Guilherme Pimentel (SNS, Pisa)
