With smooth potentials, fundamental solutions have explicit short-time formulas found by Fujiwara
These formulas fail for non-smooth potentials, where dispersive estimates break down
This paper shows the principal asymptotic term still resembles the smooth case
The analysis hinges on wave packet transforms and classical trajectory computations
Asymptotic behavior of fundamental solutions for Schrödinger equations with rough potentials
This paper examines the short-time asymptotic behavior of fundamental solutions for time-dependent Schrödinger equations with non-smooth potentials that have at most quadratic spatial growth. It shows that the principal part of the asymptotic expansion resembles the smooth potential case, even though dispersive estimates can fail with rough potentials. The key techniques involve wave packet transforms and classical trajectory analysis.
