Recent Updates



·      Frustrated Boundary Conditions influence local order:

Even weak topological frustration can destroy local order and replace the spontaneous magnetization of spin-1/2 chains with different types of order, separated by boundary-less wetting transitions..


·      Novel Spontaneous Symmetry Breaking mechanism in Invariant Matrix Models:

A gap in the eigenvalue distribution induces a localization of the eigenvectors. The full U(N) symmetry is spontaneously broken into a smaller one and ergodicity is lost.


·      Global Quantum Quench on a Localized Excitations:

The short time dynamics of a soliton after a quantum quench is universal: a reflected and transmitted profiles are generated, whose size and velocity depend only on the ration between the sound velocity before and after the quench


·      Local Convertibility and edge states in quantum many body systems” published in Physical Review X:

Lack of local convertibility can be understood in terms of edge state recombination and their entanglement properties, providing a characterization for Universal Quantum Simulators
