The application of the Schur-Weyl duality in the one-dimensional Hubbard model
Dorota Jakubczyk
We present the application of the Schur-Weyl duality in the one-dimensional Hubbard model in the case of half-filled system of any numer of atoms. We replace the actions of the dua…
Ground-state and magnetocaloric properties of a coupled spin-electron double-tetrahedral chain (exact study at the half filling)
Lucia Galisova, Dorota Jakubczyk
Ground-state and magnetocaloric properties of a double-tetrahedral chain, in which nodal lattice sites occupied by the localized Ising spins regularly alternate with triangular clu…
An alternative approach to the construction of Schur-Weyl transform
Paweł Jakubczyk, Yevgen Kravets, Dorota Jakubczyk
We propose an alternative approach for the construction of the unitary matrix which performs generalized unitary rotations of the system consisting of independent identical subsyst…
On the application of Jucys-Murphy operators in the Hubbard model
Dorota Jakubczyk, Paweł Jakubczyk, Yevgen Kravets
The operator techniques based on the Jucys-Murphy operators were applied in the procedure of an immediate diagonalization of the one-dimensional Hubbard model. The Young orthogonal…
Entanglement of one-magnon Schur-Weyl states
Pawel Jakubczyk, Yevgen Kravets, Dorota Jakubczyk
We investigate the entanglement properties of symmetry states of the Schur-Weyl duality. Our approach based on reduced two-qubit density matrices, and concurrence as the measure of…
