General PT-Symmetric Matrices
Jia-wen Deng, Uwe Guenther, Qing-hai Wang
Three ways of constructing a non-Hermitian matrix with possible all real eigenvalues are discussed. They are PT symmetry, pseudo-Hermiticity, and generalized PT symmetry. Parameter…

Time-dependent Hamiltonians with 100% evolution speed efficiency
Raam Uzdin, Uwe Guenther, Saar Rahav +1
The evolution speed in projective Hilbert space is considered for Hermitian Hamiltonians and for non-Hermitian (NH) ones. Based on the Hilbert-Schmidt norm and the spectral norm of…
