A Pedestrian's Way to Baxter's Bethe Ansatz for the Periodic XYZ Chain
Xin Zhang, Andreas Klümper, Vladislav Popkov
A chiral coordinate Bethe ansatz method is developed to study the periodic XYZ chain. We construct a set of chiral vectors with fixed number of kinks. All vectors are factorized an…
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…
Gravitational wave constraints on non-birefringent dispersions of gravitational waves due to Lorentz violations with GWTC-3
Cheng Gong, Tao Zhu, Rui Niu +5
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry in the gravitational interaction. In…
