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…
Multipole analysis on gyroscopic precession in gravity with irreducible Cartesian tensors
Bofeng Wu, Xin Zhang
In gravity, the metric, presented in the form of the multipole expansion, for the external gravitational field of a spatially compact supported source up to order is…
Phantom Bethe roots in the integrable open spin chain
Xin Zhang, Andreas Klümper, Vladislav Popkov
We investigate special solutions to the Bethe Ansatz equations (BAE) for open integrable Heisenberg spin chains containing phantom (infinite) Bethe roots. The phantom Bethe r…
Phantom Bethe excitations and spin helix eigenstates in integrable periodic and open spin chains
Vladislav Popkov, Xin Zhang, Andreas Klümper
We demonstrate the existence of special phantom excitations for open and periodically closed integrable systems at the example of the Heisenberg spin chain. The phantom excit…
