Control of a qubit state by a soliton propagating through a Heisenberg spin chain
S. Varbev, I. Boradjiev, R. Kamburova +1
We demonstrate that nonlinear magnetic solitary excitations (solitons) traveling through a Heisenberg spin chain may be used as a robust tool capable of coherent control of the qub…
Dynamics of a periodic chain coupled to a photon mode
S. Varbev, I. Boradjiev, H. Tonchev +1
We study the real-time dynamics of a periodic system exposed to a composite field comprised of a constant homogeneous magnetic and a quantized circularly polarized electromagn…
On MKdV Equations Related to the Affine Kac-Moody Algebra
Vladimir S. Gerdjikov, Dimitar M. Mladenov, Aleksander A. Stefanov +1
We have derived a new system of mKdV-type equations which can be related to the affine Lie algebra . This system of partial differential equations is integrable via th…
Soliton equations related to the affine Kac-Moody algebra D^(1)_4
Vladimir S. Gerdjikov, Dimitar M. Mladenov, Aleksander A. Stefanov +1
We have derived the hierarchy of soliton equations associated with the untwisted affine Kac-Moody algebra D^(1)_4 by calculating the corresponding recursion operators. The Hamilton…
Integrable equations and recursion operators related to the affine Lie algebras
Vladimir S. Gerdjikov, Dimitar M. Mladenov, Aleksander A. Stefanov +1
We have derived a family of equations related to the untwisted affine Lie algebras using a Coxeter reduction. They represent the third member of th…
Correlation between T_c and the Cu 4s level reveals the mechanism of high-temperature superconductivity
Z. D. Dimitrov, S. K. Varbev, K. J. Omar +3
Band structure trends in hole-doped cuprates and correlations with T_c are interpreted within the s--d exchange mechanism of high-T_c superconductivity. The dependence of T_c on th…
