`Land.jl` fails on CPU

[imreddyTeja]

Describe the bug

Running both experiments/benchmarks/land.jl and experiments/long_runs/land.jl on CPU fails with error

ERROR: LoadError: DomainError with -0.5324317979740165:
Exponentiation yielding a complex result requires a complex argument.
Replace x^y with (x+0im)^y, Complex(x)^y, or similar.

To Reproduce

Run either experiments/benchmarks/land.jl and experiments/long_runs/land.jl on CPU. They sometimes will run without error if the tf and Δt values are changed.
