Bug with formdouble::zeroAdditional

Vukics, András — Tue, 21 Jan 2020 08:49:14 -0000

formdouble::zeroAdditional seems to cause a problem with ostringstream, probably because width=0 causes some undefined behavior. Why not use width=1 ?

Homodyned – error in implementation

Vukics, András — Fri, 07 Jul 2017 12:50:42 -0000

The non-Hermitian part in Homodyned doesn’t correspond correctly to the jump operators (Hermitian conjugate [& factor of 2?] missing) as can be ascertained by simple inspection of the ctor.

Finite-temperature mode fails in composites

Vukics, András — Wed, 15 Jan 2014 21:30:28 -0000

There is an error in the normalization after photon-absorption when finite-temperature modes are used in composites (MCWF evolution). This might entail that the jump probability is incorrect as indicated also by incorrect time averages.

BinarySystem and Composite produce the same.

Testcase:
TwoModes_d --nTh0 .05 --nTh1 .025 --logLevel 2 --dc 1 --cutoff0 20 --cutoff1 30 --kappa0 20 --kappa1 40 --timeAverage

@ time=0.016 and 0.0211667 the error is manifest, since the photonnumber should never become non-integer in this case (on the next timestep, the renormalization corrects it).

The incorrect value of the photon number equals the inverse of the dimension of the other system, which explains why the error was not seen with a single mode.

Sorry, looks like I left this print => print_v migration in a rather incompleted state … Thanks, it seems fine now!
