2(a) and 2(b) of the main paper, showing the QSF for the Bose-Hubbard chain in the strongly interacting superfluid regime at low fillings, together with the Lieb branches of

In this paper, we show that the non equilibrium dynamics following a single local quench out of the ground state is suf- ficient to unveil the excitation spectrum of a

The aim of this paper is to show that the retrodictive approach of quantum physics [10, 11], which is comple- mentary to the usual predictive one, provides interesting physical

In the domain of continuous variables and intense beams to which we restrict the present discussion, one shows that the situations where one records quadrature fluctuations above

First, taking advantage of an example of partly compressible incompatibility, we show that the notions of joint measurability and coexistence (i.e., joint measurability of

So there is a dear difference between this CB spectrum and the spectra that were calculated before: interference terms between photons coming from different atomic rows show up,

For a signal with temporally fluctuating polariza- tion we still obtained the correct value, whereas this was not the case for a standard polarimetric measurement. Financial
