A first study of strong isospin breaking effects in lattice QCD using truncated polynomials
David Albandea, Simon Kuberski, Fernando P. Panadero
Computing derivatives of observables with respect to parameters of the theory is a powerful tool in lattice QCD, as it allows the study of physical effects not directly accessible…
Chiral and isospin breaking in the two-flavor Schwinger Model
David Albandea, Pilar Hernández
The Schwinger model with two massive fermions is a nontrivial theory for which no analytical solution is known. The strong coupling limit of the theory allows for different semicla…
Lattice techniques to investigate the strong problem: lessons from a toy model
David Albandea, Guilherme Catumba, Alberto Ramos
Recent studies have claimed that the strong problem does not occur in QCD, proposing a new order of limits in volume and topological sectors when studying observables on the l…
Strong CP problem in the quantum rotor
David Albandea, Guilherme Catumba, Alberto Ramos
Recent studies have claimed that the strong problem does not occur in QCD, proposing a new order of limits in volume and topological sectors when studying observables on the l…
