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…

Tensor Networks: a quantum-information perspective on numerical renormalization groups
Pietro Silvi
Exact many-body quantum problems are known to be computationally hard due to the exponential scaling of the numerical resources required. Since the advent of the Density Matrix Ren…
