Finite complexity of the de Sitter vacuum
Suddhasattwa Brahma, Lucas Hackl, Moatsem Hassan +1
The ER=EPR conjecture states that quantum entanglement between boundary degrees of freedom leads to the emergence of bulk spacetime itself. Although this has been tested extensivel…
Momentum-space entanglement entropy in de Sitter
Suddhasattwa Brahma, Jaime Calderón-Figueroa, Moatasem Hassan +1
We study the momentum-space entanglement between the sub- and super-Hubble modes of a spectator scalar field, with a cubic interaction, in de Sitter space. Momentum-space en…
Quasideterminant solutions of an integrable chiral model in two dimensions
Bushra Haider, M Hassan
The Darboux transformation is used to obtain multisoliton solutions of the chiral model in two dimensions. The matrix solutions of the principal chiral model and its Lax pair are e…
The U(N) chiral model and exact multi-solitons
Bushra Haider, M. Hassan
We use a binary Darboux transformation to obtain exact multisoliton solutions of the principal chiral model and its noncommutative generalization. We also show that the exact multi…
On algebraic structures in supersymmetric principal chiral model
Bushra Haider, M. Hassan
Using the Poisson current algebra of the supersymmetric principal chiral model, we develop the algebraic canonical structure of the model by evaluating the fundamental Poisson brac…
Darboux transformation of the generalized coupled dispersionless integrable system
M. Hassan
The Darboux transformation on matrix solutions to the generalized coupled dispersionless integrable system based on some non-abelian Lie group, is studied and the solutions are sho…
