Universality in relaxation of spin helices under the - spin chain dynamics
Vladislav Popkov, Marko Žnidarič, Xin Zhang
We describe dynamics of transverse spin-helix state (SHS) -- a product state with spatially rotating magnetization -- under anisotropic Heisenberg XXZ spin chain evolution. Due to…
Chiral basis for qubits and spin-helix decay
Vladislav Popkov, Xin Zhang, Frank Göhmann +1
We propose a qubit basis composed of transverse spin helices with kinks. Unlike the usual computational basis, this chiral basis is well suited for describing quantum states with n…
Dissipative cooling towards phantom Bethe states in boundary driven XXZ spin chain
Vladislav Popkov, Mario Salerno
A dissipative method that allows to access family of phantom Bethe-states (PBS) of boundary driven XXZ spin chains, is introduced. The method consists in coupling the ends of the o…
Invariant subspaces and explicit Bethe vectors in the integrable open spin $\XYZ$ chain
Xin Zhang, Andreas Klümper, Vladislav Popkov
We derive a criterion under which splitting of all eigenstates of an open $\XYZ$ Hamiltonian with boundary fields into two invariant subspaces, spanned by chiral shock states, occu…
Boundary driven chain: Exact inhomogeneous triangular matrix product ansatz
Vladislav Popkov, Xin Zhang, Tomaz Prosen
We construct an explicit matrix product ansatz for the steady state of a boundary driven spin- chain for arbitrary local polarizing channels at the chain's en…
Chiral coordinate Bethe ansatz for phantom eigenstates in the open XXZ spin- chain
Xin Zhang, Andreas Kluemper, Vladislav Popkov
We construct the coordinate Bethe ansatz for all eigenstates of the open spin- XXZ chain that fulfill the phantom roots criterion (PRC). Under the PRC, the Hilbert space s…
