Textures as a phase-transition probe for quantum spin chains
Heitor P. Casagrande, Isaac M. Carvalho, William J. Munro +1
The idea of quantum texture has been recently proposed and used as a tool for quantifying coherences and for quantum gate identification. In this work we offer a study on its usage…
Fractal Path Strategies for Efficient 2D DMRG Simulations
Oliver R. Bellwood, Heitor P. Casagrande, William J. Munro
Numerical simulations of quantum magnetism in two spatial dimensions are often constrained by the area law of entanglement entropy, which heavily limits the accessible system sizes…
Tensor-Networks-based Learning of Probabilistic Cellular Automata Dynamics
Heitor P. Casagrande, Bo Xing, William J. Munro +2
Algorithms developed to solve many-body quantum problems, like tensor networks, can turn into powerful quantum-inspired tools to tackle problems in the classical domain. In this wo…
Complexity of spin configurations dynamics due to unitary evolution and periodic projective measurements
Heitor P. Casagrande, Bo Xing, Marcello Dalmonte +3
We study the Hamiltonian dynamics of a many-body quantum system subjected to periodic projective measurements which leads to probabilistic cellular automata dynamics. Given a seque…
Supervised Training of Neural-Network Quantum States for the Next Nearest Neighbor Ising model
Zheyu Wu, Remmy Zen, Heitor P. Casagrande +2
Different neural network architectures can be unsupervisedly or supervisedly trained to represent quantum states. We explore and compare different strategies for the supervised tra…
Analysis of a density matrix renormalization group approach for transport in open quantum systems
Heitor P. Casagrande, Dario Poletti, Gabriel T. Landi
Understanding the intricate properties of one-dimensional quantum systems coupled to multiple reservoirs poses a challenge to both analytical approaches and simulation techniques.…
