Assume the structural assumptions (SC), let $5>0$, and let $10_0^5$ be initial data of the form $10_0^5=\widehat{\vec V_0}v_0^5+O(\sqrt{5})$ in $L^2(\mathbb R^d)$. Let…

The paper considers the Herman–Kluk approximation to the evolution of semiclassical wave packets for a matrix-valued Hamiltonian, with $boldsymbol{ u}0$ denoting the initial data,…
