About the workshop
Description
This workshop is to investigate and to discuss new-types of fermions on the lattice, i.e. staggered Wilson, staggered overlap and minimally doubled fermions and so on. These fermions give us new perspectives on lattice fermions, which could improve the current lattice simulations. Indeed the new formulations of Wilson and overlap fermions based on staggered fermions would drastically reduce computational costs in lattice simulations, while those still keep several virtues of Wilson, domain-wall, or overlap fermions. The subjects of the workshop include the index theorem and the topological charge, the U(1) problem, the staggered flavor structure, the Aoki phase and its order of phase transition, chiral perturbation theory and the strong coupling expansion in the new-types of lattice fermions. Based on these theoretical foundations, the workshop aim at promoting the kernel constructions or improvements, and realistic lattice simulations with the new-types of fermions.
Subjects to be discussed include
- Symmetries of new types of lattice fermions
- Discretization errors of new types of lattice fermions and their improvement
- Parity phase structure and the U(1) problem in staggered Wilson and staggered domain-wall fermions
- Chiral perturbation theory for new types of lattice fermions
- Hadron masses with new types of lattice fermions at strong coupling and in MC simulations
- Related topics.
One-day workshop
We will have a one-day mini-workshop on Feb.17, in which we discuss the problem of lattice fermions in a wider point of view. One-day workshop subjects will be...
- extensions of chiral effective theory
- practical implementations of chiral fermions
- methods to study topology-related quantities
- applications for finite density(?)
