Schur--Horn bound on field-free molecular orientation at finite temperature
Tanveer Ahmad
The maximum field-free orientation attainable from a \emph{thermal} molecular ensemble within a finite rotational subspace has not been characterised analytically. Here we derive a…

Tikhonov-regularised projected gradient flow for equality-constrained bilinear quantum control
Tanveer Ahmad
We study a projection-type gradient flow for equality-constrained maximisation of a smooth bilinear control objective on , eliminating Lagrange mul…
