On the perturbed periodic Schrödinger operators with separate resonant embedded eigenvalues
Kang Lyu, Chuanfu Yang
In this paper, we consider Schrödinger operators on given by \begin{align} Hu=(H_0+V)u=-u^{\prime\prime}+V_0u+Vu,\nonumber \end{align} where is real, -per…

Sharp spectral transition for embedded eigenvalues of perturbed periodic Dirac operators
Kang Lyu, Chuanfu Yang
We consider the Dirac equation on \begin{align} Ly= \begin{pmatrix} 0&-1 1&0 \end{pmatrix} \begin{pmatrix} y_1 y_2 \end{pmatrix}'+ \begin{pm…
