Welcome to the hybrid Journal Club!

After a long pause due, again, to covid, the journal club "Quantum black holes on the plateau" will restart in a brand new, hybrid mode

where: IPhT, CEA Saclay and on-line

when:  every other Friday at 2:15 p.m.

topics:  recent papers related to the quantum structure of black holes, bulk EFT, Page curves, etc.

how it works: one person prepares a presentation, and everyone else reads the paper and prepares for a discussion. Papers can either be chosen from the suggested readings on this website, or the speaker can come up with his/her own paper to read, which should fit with the general topic of the journal club.  

practical:

• directions to the IPhT can be found here
• the room will either be amphi Bloch or salle Itzykson, both on the IPhT  ground floor, depending on covid-related restrictions  
• wearing a mask is compulsory, except for the speaker
  
• internet is provided via eduroam or orme-enregistrement/access
• outside participants who would like to spend the entire day at the IPhT can contact  Monica for lunch arrangements
  
• the videoconferencing link and password for the on-line participants will be sent by e-mail to those registered to the JC mailing list     
• the JC will not be recorded
  

The first three journal clubs are:

•  on Tuesday, Nov 23rd, at 10 a.m. (note unusual date & time!) in Amphi Bloch, Nicolas Kovensky will present "Asymptotically Free AdS3/CFT2" by Balthasar, Giveon, Kutasov and Martinec, https://arxiv.org/abs/2109.00065 and "AdS3's with and without BTZ's" by Martinec https://arxiv.org/abs/2109.11716
  
  
• on Friday, April 8th, at 10:00 a.m. in salle Itzykson, Ioannis Tsiares will present "Transcending the ensemble: baby universes, spacetime wormholes, and the order and disorder of black hole information" by Marolf and Maxfield  https://arxiv.org/abs/2002.08950.
