A positive tensor network approach for simulating open quantum many-body systems
A. H. Werner, D. Jaschke, P. Silvi +4
Open many-body quantum systems play an important role in quantum optics and condensed-matter physics, and capture phenomena like transport, interplay between Hamiltonian and incohe…
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…
Lattice Gauge Tensor Networks
Pietro Silvi, Enrique Rico, Tommaso Calarco +1
We present a unified framework to describe lattice gauge theories by means of tensor networks: this framework is efficient as it exploits the high amount of local symmetry content…
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…
