static remainder method

[samaneh]

Dear Developers
There is a paper about the modified static remainder method
"PRB 87, 165124 (2013)" which describes a method that
converges for a smaller number of empty bands
in a good way.
Is this method implemented in the yambo code?
All the best

Dear Samaneh,

this method it is not implemented but other methods as:
PRB 78, 085125 (2008)
and
PRB 85, 085126 (2012)
are implemented in order to speed up convergences.

Next time please, post your question in the appropriate subforum. This is not a topic for ypp, keeping the topic in order, helps user to find solutions.
Best,
Daniele

Dear Dr. Daniele,

Ok. Thanks for quick reply.
So, would you please tell me how can I choose the
method by PRB 85, 085126 (2012) to run e.g. yambo -g n -p p?

Dear Samaneh,
in the version 4.0, in the GW input you will find the variable:

Code: Select all

GTermKind= "none" 

You can set to:
"BG" Bruneval-Gonze, --> PRB 78, 085125 (2008)
or
"BRS" Berger-Reining-Sottile --> PRB 85, 085126 (2012)

As I told you before I will move this post in the proper subforum.

Best,
Daniele

Dear Dr Daniele,

Ok
I apologize since I do not know
where is the proper sub forum for this post
if you moved it please tell me where it is.
But the version 4.0, is testing and is not stable
yet.
In other versions like 3.4.1rev61 I could not find this variable
and it means that in these versions non of these methods
are implemented?

Thanks

Dear Samaneh,
this feature it is implemented in the new version ie (4.0) which is a devel version.
The post will be moved in the Self energy subforum as you are asking for method to accelerate self-energy computation.
