Asymptotic behaviour of determinants through the expansion of the Moyal star product
Maurizio Fagotti, Vanja MariÄ
We work out a generalization of the Szegö limit theorems on the determinant of large matrices. We focus on matrices with nonzero leading principal minors and elements that decay t…

Macroscopic Quantum States and Universal Correlations in a Disorder-Order Interface Propagating over a 1D Ground State
Vanja MariÄ, Florent Ferro, Maurizio Fagotti
We consider translationally invariant quantum spin- chains with local interactions and a discrete symmetry that is spontaneously broken at zero temperature. We envisio…

Disorder-Order Interface Propagating over the Ferromagnetic Ground State in the Transverse Field Ising Chain
Vanja MariÄ, Florent Ferro, Maurizio Fagotti
We consider time evolution of order parameters and entanglement asymmetries in the ferromagnetic phase of the transverse-field Ising chain. One side of the system is prepared in a…
