New Construction of Eigenstates and Separation of Variables for SU(N) Quantum Spin Chains
Nikolay Gromov, Fedor Levkovich-Maslyuk, Grigory Sizov
We conjecture a new way to construct eigenstates of integrable XXX quantum spin chains with SU(N) symmetry. The states are built by repeatedly acting on the vacuum with a single op…
On the Exact Interpolating Function in ABJ Theory
Andrea Cavaglià, Nikolay Gromov, Fedor Levkovich-Maslyuk
Based on the recent indications of integrability in the planar ABJ model, we conjecture an exact expression for the interpolating function h(λ_1,λ_2) in this theory. Our conjecture…
Quark--anti-quark potential in N=4 SYM
Nikolay Gromov, Fedor Levkovich-Maslyuk
We construct a closed system of equations describing the quark--anti-quark potential at any coupling in planar N=4 supersymmetric Yang-Mills theory. It is based on the Quantum Spec…
