The domain of utilisation of quantum field theory in curved spacetime has found many new applications in particle, nuclear and condensed matter physics. Aside for suggesting novel intersections between quantum fields and gravity, an unexplored landscape of original ideas is taking shape and inspiring the formulation of new exciting problems and ramifications of the theory.

This 2-days workshop brings together researchers working in different areas of quantum field theory with interest in its curved space applications in the area of gravity and beyond. The goal of the workshop is to exchange ideas on what is or is expected soon to become topical and discuss potential interdisciplinary interactions in a stimulating and collaborative environment.

The workshop will take place in the relaxing setting of Keio University Campus in Hiyoshi. This is conveniently located just a few steps from the Hiyoshi main metro station (Toyoko Line and Meguro Line) and a short train ride to the main attractions of Tokyo area: Shibuya and Shinjuku districts, the Yokohama bay, the old capital of Kamakura.

The workshop's venue is the central "Raiōsha" building, whose name literally means "a place for coming and going". The name of the building refers to a poem by Fukuzawa Yukichi, the founder of Keio university, celebrating the importance of gathering to foster conversation, confrontation and collaboration.
