Disorder-induced dynamical Griffiths singularities after certain quantum quenches
José A. Hoyos, R. F. P. Costa, J. C. Xavier
We demonstrate that in a class of disordered quantum systems the dynamical partition function is not an analytical function in a time window after certain quantum quenches. We rela…

Self-adjoint extension approach for singular Hamiltonians in (2+1) dimensions
Vinicius Salem, Ramon F. Costa, Edilberto O. Silva +1
In this work, we review two methods used to approach singular Hamiltonians in (2+1) dimensions. Both methods are based on the self-adjoint extension approach. It is very common to…
