DOI: 10.1007/s00220-021-04190-z
Abstract: We introduce a shell model of turbulence featuring intermittent behaviour with anomalous power-law scaling of structure functions. This model is solved analytically with the explicit derivation of anomalous exponents. The solution associates the intermittency with… read more here.

DOI: 10.1103/physrevc.100.014316
Abstract: In nuclear structure calculations, the choice of a limited model space, due to computational needs, leads to the necessity to renormalize the Hamiltonian as well as any transition operator. Here, we present a study of… read more here.
