abstract = {<p style="text-align: justify;">A linearized transformed $L1$ Galerkin finite element method (FEM) is presented for numerically solving the multi-dimensional time fractional Schrödinger
equations. Unconditionally optimal error estimates of the fully-discrete scheme are
proved. Such error estimates are obtained by combining a new discrete fractional
Grönwall inequality, the corresponding Sobolev embedding theorems and some inverse inequalities. While the previous unconditional convergence results are usually
obtained by using the temporal-spatial error spitting approaches. Numerical examples are presented to confirm the theoretical results.</p>},
