* xmds2 model of Gena's 4-level system.Simon Rochester2011-08-214-0/+3435
| | | | | | | | GenerateGenasSystem.nb: generate evolution equations GenasSystemPlots: code for reading output data, converting complex field amplitudes to rotation angle/ellipticity, and plotting
* Added and commented out return to avoid density matrix replotEugeniy Mikhailov2011-08-201-3/+5

* Readme updated since Rabi now in [1/s]Eugeniy Mikhailov2011-08-201-5/+5
|
* Eta parameter fixes, Rabi measured in [1/s] and z in [m]Eugeniy Mikhailov2011-08-201-39/+30
| | | | | Very tedious check of units, now everything in SI units which is a bit painful for Rabi frequencies.
* Parameters split to groups, initialization cells addedEugeniy Mikhailov2011-08-171-503/+341

* Add tmin and move pulse center to t=0Eugeniy Mikhailov2011-07-161-5/+6
|
* Make dt = dzEugeniy Mikhailov2011-07-161-5/+5
| | | | | | | * as Simon discovered dt must equal to dz (in normilized units) then some term cancels in derivatives calculations * as result tpts is not a free parameter anymore but locked to length of the cell and number of zpts
* t and z limits are given independentlyEugeniy Mikhailov2011-07-141-0/+2
| | | | | * something fishy with navy code, I decrease length by factor of 2 and delays for vacuum field is exactly the same
* Canonic EIT - control field (3) is offEugeniy Mikhailov2011-07-131-1/+1

* Adjust grid sizeEugeniy Mikhailov2011-07-131-1/+1
| | | | | Close to optimal grid size for this problem. Increasing the number of points by 10 in both directions almost does not change output

* Calculate canonic EIT caseEugeniy Mikhailov2011-07-121-7/+7
| | | | | | | | * field 1 is weak and has Gaussian temporal profile * field 2 is strong * field 3 is off * vacuum propagated field start similar to field 1 * cell length enlarged to see pulse delay
* Output format changed. Output |Om| instead of amplitudeEugeniy Mikhailov2011-07-121-1/+1
| | | | | * this take care of complex part which seems to be disregarded with current format for write statement

* Replaced FourLevelPulseProp_v*_Double.f95 with FourLevelPulseProp_Double.f95 ↵Simon Rochester2011-07-123-716/+8
| | | | | | and edited makefile accordingly. Added t variable to the output file Movie4level.dat for plotting purposes.
* v2 and v3 are now the same except output filenamesEugeniy Mikhailov2011-07-102-25/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v2 and v3 were design to be the same except difference of light fields time profiles in initial conditions. But looks like navy guys during edits drift both versions from correct realization. After bug fixes and mergers of insignificant details. I went peace by peace comparison and removed insignificant differences * print time elapsed * print the same other statements to output * same spaces in the statements so they are not shown as diffs * same number of t point * z frames number calculated the same * L is the same * density is the same * remove trailing semicolons to make lines the same * Omcpeak=0.1 in both files Then I look at crucial differences * k1=1-(W32+W31+W34)*dt -> W34 taken in account * j2=W21*dt * j8=W41*dt added to v3 to take in account decay of rho44 to rho11 * W42=1 in v2 it used to be zero * Omc is constant in both cases * rho14 in v3 had product of two rhos, now it the sum as in v2 * rho24 in v3 was calculated differently form v2: no conjg(Omc) was used * the fix is taken from v2 and seems to match our xmds code The only difference remained is output file names.
* Remove references of Ompeak. Ompeak -> Omcpeak to fix navy's typoEugeniy Mikhailov2011-07-102-4/+4

* Modified navy source to be f95 compatibleEugeniy Mikhailov2011-07-103-0/+1433
| | | | | | | | | | * in open statement 'name' replcaed with 'file' * pause statement replaced with write(*,*) Small bug fix in FourLevelPulseProp_v3_Double.f95 * data output file namesi fixed. Code marked v3 outputs now to _v3 files and not _v2 as before. * the Ompeak variable was not declared
