We are glad to announce the second ALF User Workshop: ALF Workshop 2022.

Registrations are already open: https://alfworkshop2022.sciencesconf.org/.

The event will take place online from 14/Feb/2022 to 18/Feb/2022 and is aimed at both beginners and advanced users. A detailed program is not yet available, but it will include:

• hands-on sessions with ALF
• presentations: QMC theoretical basis, ALF particulars, and recent results
• contributed talks by workshop participants

Whether you’d like to learn the basics of ALF, or could use some help with implementing your own Hamiltonian or measurement, this workshop puts the whole team at your disposal.

The latest stable version of the package is now ALF 2.2.

The main improvements with respect to 2.1 are:

• HDF5 data format is supported (see documentation Sec. 5.7.2, 6.2, 6.3)
• bond multiplicity is automatically taken care of by the code

To use HDF5 you’ll need to recompile the package.

Notice that, due to this changes, this release is not strictly backwards compatible:

• the argument DEVEL/DEVELOPMENT is no longer a MACHINE name, but an optional switch in script configure.sh
• and Hopping_Matrix_Type%Multiplicity is now a private member

Check the CHANGELOG and documentation for further details.

Check out our latest poster, created for the FOR1807 International Conference.

You can download it in both PNG and PDF formats, as well as the summary slide for the 2-minute poster slam session.

The latest stable version of the package is now ALF 2.1.

The main change from 2.0 is under the hood:

• Hamiltonians are now written as submodules of Hamiltonian_main_mod, using the class ham_base, which contains all the stuff common to Hamiltonians - a more economical, object oriented approach that’s a time saver and better structures the code.

Notice that, due to this change, this release is not backwards compatible: check its CHANGELOG and documentation for details and the modifications necessary to adapt existing Hamiltonians to ALF 2.1.

Great news:

The Unitary Fund awarded us a microgrant for improving ALF’s python interface, pyALF.

We just concluded our first ALF User Workshop. After this intense and rewarding week, some additional 50+ researchers can now do QMC simulations using ALF and pyALF in their own machines with many having already started producing their own results.

Being forced into virtual rooms by the pandemic, we faced challenges such as wide time zone differences, but could count with more than twice as many participants as initially planned and, as a by-product of the online conference, we produced a number of video lectures, which will soon be publicly online.

The updated program for the ALF User Workshop (05/Oct - 09/Oct) is out!

Please check the Conference’s Website for more information and registering.

The program is also available in the PDF format.

Due to organizational issues we are postponing the ALF User Workshop to:
5th - 9th of October 2020
