Unconstrained Tree Tensor Network: An adaptive gauge picture for enhanced performance
Matthias Gerster, Pietro Silvi, Matteo Rizzi +3
We introduce a variational algorithm to simulate quantum many-body states based on a tree tensor network ansatz which releases the isometry constraint usually imposed by the real-s…
From classical to quantum criticality
Daniel Podolsky, Efrat Shimshoni, Pietro Silvi +4
We study the crossover from classical to quantum phase transitions at zero temperature within the framework of theory. The classical transition at zero temperature can be des…
Full characterization of the quantum linear-zigzag transition in atomic chains
Pietro Silvi, Gabriele De Chiara, Tommaso Calarco +2
A string of repulsively interacting particles exhibits a phase transition to a zigzag structure, by reducing the transverse trap potential or the interparticle distance. The transi…
