Spin Chains from large- QCD at strong coupling
David Berenstein, Hiroki Kawai
We study the strong coupling expansion of large QCD in various dimensions, reformulating the Kogut-Susskind Hamiltonian on a square lattice in terms of (constrained) one dimens…

Integrability and Conformal Blocks for Surface Defects in SYM
Adolfo Holguin, Hiroki Kawai
We study various aspects of half-BPS surface defect operators in SYM. For defects on generic points on the moduli space we use superconformal symmetry to fix the fo…

Galaxy-galaxy strong lensing cross-section with fuzzy dark matter model
Hiroki Kawai, Massimo Meneghetti
The galaxy-galaxy strong lensing (GGSL) cross-section in observed galaxy clusters has been reported to be more than an order of magnitude higher than the theoretical prediction by…
