Witryna10 kwi 2024 · Both Hermitian and Non-Hermitian Landau-Zener (LZ) models are described by 2 2 matrices of the form H ( ) 2 (t) = vt g g vt ; (S.1) where \+" refers to the Hermitian and \ " refers to the non-Hermitian model. The eigenvalues of the non-Hermitian matrix are given in Fig.S1b and is presented alongside the eigenvalues for … Witryna13 kwi 2024 · It is natural to expect that the spectrum of the Bethe subalgebra in a “generic” representation of the Yangian is simple. The spectrum is simple if and only if. (1) there is a cyclic vector in the representation; (2) operators from the Bethe subalgebra act semisimply on the representation.
