The notion of global symmetry in quantum field theory has been generalized in many interesting directions including p-form symmetries higher-form symmetries and non-invertible symmetries.
We study correlators of insertions along 1/2 BPS line defects in the holographic dual to type IIB string theory in AdS3×S3×T4 with mixed Ramond-Ramond and Neveu Schwarz-Neveu Schwarz three-form flux.
Understanding the mechanism of thermalization in gauge theories is one of the challenging problems of contemporary research.
The feebly-interacting massive particle (FIMP) paradigm offers an intriguing solution to the dark matter (DM) puzzle with FIMPs produced via the freeze-in mechanism due to extremely weak interactions with the standard model (SM) plasma.
Holographic description of the Nieh-Yan anomaly.
In 2 dimensions holographic duality gives the possibility of studying quantum gravity in terms of the dual SYK quantum mechanical theory. A particularly capturing model involves two coupled SYK systems.
