Finding the best pseudopotential in SIESTA involves varying parameters like cutoff radius and electronic configuration, but additional guidance on specific parameters may be needed for improved accuracy. Beginners often seek recommendations for software to visualize crystal structures, particularly for gold nanoparticles. Input files for gold nanoparticle structures are also requested to aid in simulations. Community members are encouraged to share resources and advice for newcomers to enhance their understanding and application of SIESTA. Overall, collaboration and shared resources are vital for optimizing simulations in SIESTA.

Hello , is there anyone to help me.
I'm just a beginer. I was trying to find out the pseudopotential for different elements.
Do you have any suggetions ? I am using seista for this.
I'll be greatful if you can help me.

My problems are.

1. How to find out the best pseudopotential ?
I'm varing the cutoff radius and the electronic configuration, is there any parameters which is to be changed to get a more accurate pseudopotential ?

hi, i am a beginner in siesta. can some suggest me a drawing software for the cyrstal structure of gold nanoparticle in siesta. or can some one send me a input file for the crystal structure of gold nanoparticles.??

Thread 'Unexpected irregular reflection signal from a high-finesse cavity'

I am observing an irregular, aperiodic noise pattern in the reflection signal of a high-finesse optical cavity (finesse ≈ 20,000). The cavity is normally operated using a standard Pound–Drever–Hall (PDH) locking configuration, where an EOM provides phase modulation. The signals shown in the attached figures were recorded with the modulation turned off. Under these conditions, when scanning the laser frequency across a cavity resonance, I expected to observe a simple reflection dip. Instead...
