Conformal defects of general dimensions at finite temperature
Yucheng Li, Haruki Nakayama, Tatsuma Nishioka
We consider defect conformal field theories (DCFTs) at finite temperature, where a -dimensional conformal defect wraps the thermal circle. Extending the previous study of line d…

Holographic defect CFTs with Dirichlet end-of-the-world branes
Haruki Nakayama, Tatsuma Nishioka
We construct a holographic model of defect conformal field theories (DCFTs) with defects of codimension greater than one. Our construction generalizes the AdS/BCFT model by anchori…

Energy Conditions and Quantum Information
Norihiro Iizuka, Akihiro Ishibashi, Kengo Maeda +2
The concept of energy lies at the foundation of physical science. In general relativity and quantum field theory, the positivity and conservation of energy are encapsulated by the…
