Résumé |
Integrability proves to be a powerful tool in applications to holographic gauge theories such as N=4 SYM and ABJM, allowing for exact results concerning the spectrum and beyond. However, the string theory on AdS_3 x S^3 x T^4 has resisted many attempts to be solved in a similar manner, primarily due to the presence of massless modes. These modes introduce complications in certain steps of the standard derivation process. In this presentation, I will report on the progress made in solving this model using the Quantum Spectral Curve (QSC) method. Nonetheless, the massless sector of the model remains somewhat enigmatic.
Subsequently, I will shift the discussion to the BFKL regime of N=4 SYM, which benefits from a well-established QSC description. Surprisingly, it shares some features with the AdS3 case. This work is ongoing, and many mysteries and open questions persist. I look forward to a lively discussion of these topics during the informal event. |
