Black hole radial geometry from a quantum spin chain
Boris A. Khanikati
We show that the radial differential equation for a scalar field in an anti-de Sitter black brane background can be encoded in an exactly solvable semi-infinite spin chain independ…
Emptiness formation in the Lieb-Liniger gas: hydrodynamic instantons and a conjectured rate function
Boris A. Khanikati, Alexander G. Abanov
We study the emptiness formation probability (EFP) in the ground state of the repulsive one-dimensional Lieb-Liniger Bose gas. For a macroscopic empty interval of length , its…
On the collapse of three point vortices on surfaces
Theodore D. Drivas, Boris A. Khanikati, Valeriya A. Khanikati
Point vortices represent an important reduced model describing two-dimensional ideal fluid dynamics. It is well known that there exist three-vortex configurations on the Euclidean…
Time-diffracting 2D wave vortices
Boris A. Khanikati, Konstantin Y. Bliokh
Wave vortices constitute a large family of wave entities, closely related to phase singularities and orbital angular momentum (OAM). So far, two main classes of localized wave vort…
