Disordered Kitaev chain with long-range pairing: Loschmidt echo revivals and dynamical phase transitions

open access: yes, 2019
We explore the dynamics of long-range Kitaev chain by varying pairing interaction exponent, $\alpha$. It is well known that distinctive characteristics on the nonequilibrium dynamics of a closed quantum system are closely related to the equilibrium phase

Consecutive Power Occurrences in Sturmian Words

open access: yesComptes Rendus. Mathématique
We show that every Sturmian word has the property that the distance between consecutive ending positions of cubes occurring in the word is always bounded by $10$ and this bound is optimal, extending a result of Rampersad, who proved that the bound $9 ...
