Alert: Updated RQI-N (2026) Schedule is uploaded!

The RQI(N)  meetings are the annual events of the ISRQI community where researchers across the globe working at the interface of Relativity and Quantum theory interact and exchange ideas.

The 16th edition of this meeting will take place in Mohali, India during 28 September - 02 October 2026 (both days included). Mohali is a city of the Punjab state, located in the Chandigarh tricity area, just at the foothills of Himalayas.

The venue of this meeting will be the Lecture Hall Complex of the Indian Institute of Science Education and Research, Mohali (https://maps.app.goo.gl/1qVmL1Km8G4cKDjz5).

 

The topics of the conference include:

• QFT in curved spacetime and black hole information

• Foundations of relativistic quantum field theories

• Information in QFT and quantum gravity

• Interface between quantum physics and gravity

• Quantum-foundation experiments (tabletop and space)

• Causal structure and quantum theory

• Analogue gravity
