The ALF User Workshop is aimed at both beginners and advanced users of the package and consists of three main components (July 15th-July19th):
Getting to Know ALF: tutorial, basic and advanced — starting on Monday, July 15th; ALF in Production: workgroup projects and advanced features — starting on Wednesday, July 17th; New developments in lattice fermion simulations — starting also on Wednesday, July 17th
The workshop is preceded by a (virtual only) pre-event: ALF installation, held before the official start of the workshop, on the 12th of July. In order to accommodate participants from different time zones, we plan to hold it twice, at two different times (GMT+2):
10:00 (17:00 in Beijing)
17:00 (08:00 in LA)
The main event is hybrid and will be held on Zoom and in person.
Participants are expected to have a working ALF installation at the beginning of the conference, and users new to ALF will reach the second part of the workshop with a basic knowledge of the package. It's also possible to attend only the second, more advanced part of the workshop.
As it will be a hybrid event, the sessions will be held both in person and through Zoom simultaneously. For the attendees participating online, the workshop will take place in a main common Zoom room for the presentations, and break-out rooms for individual support and workgroup meetings. And you can always chat with us at ALF's Discord server.
The fisrt part of the event is hands-on sessions where participants work through tutorial exercises (1st part) and workgroup projects (2nd part). After explanatory presentations describing ALF's usage and core aspects of its code, the organizers will remain on-call to provide any support needed. For participants wishing to give themselves a head start, there is extensive documentation available. In the second part of the workshop, participants will be able to form groups, work through simple projects, and present their results on the last day of the event. We will also have a set of lectures covering present developments in algorithms for lattice fermions. This will include hybrid Monte Carlo, constrained path, and variational approaches, as well as Lefshetz thimbles.
Participants are encouraged to submit contributions. In addition to talks by invited speakers, the event also includes contributed talks by participants.
The ALF Package
The Algorithms for LatticeFermions package provides a general open-source code for auxiliary-field quantum Monte Carlo models.
Models can be specified at minimal programming cost, on arbitrary 1- and 2-D Bravais lattices. Various sampling schemes as well as projective and finite-temperature approaches are available. Suitable for both benchmarking and state-of-the-art calculations.
