Using a Feedback-Based Quantum Algorithm to Analyze the Critical Properties of the ANNNI Model Without Classical Optimization
G. E. L. Pexe, L. A. M. Rattighieri, A. L. Malvezzi +1
We investigate the critical properties of the Anisotropic Next-Nearest-Neighbor Ising (ANNNI) model using a feedback-based quantum algorithm (FQA). We demonstrate how this algorith…
Model-Independent Quantum Phases Classifier
Felipe Mahlow, Fabrício S. Luiz, André L. Malvezzi +1
Machine learning has revolutionized many fields of science and technology. Through the -Nearest Neighbors algorithm, we develop a model-independent classifier, where the algorit…
Dynamical regimes of ultrafast kinematic vortices in the resistive state of mesoscopic superconductors
A. Presotto, E. Sardella, A. L. Malvezzi +1
A superconducting state coexists with static electrical fields under the formation of phase-slips and kinematic vortices (kV 's). Besides that, such a resistive state installed in…
Unveiling phase transitions with machine learning
Askery Canabarro, Felipe Fernandes Fanchini, André Luiz Malvezzi +2
The classification of phase transitions is a central and challenging task in condensed matter physics. Typically, it relies on the identification of order parameters and the analys…
Quantum Correlations and Coherence in Spin-1 Heisenberg Chains
A. L. Malvezzi, G. Karpat, B. Çakmak +3
We explore quantum and classical correlations along with coherence in the ground states of spin-1 Heisenberg chains, namely the one-dimensional XXZ model and the one-dimensional bi…
Vortices in a mesoscopic superconducting circular sector
Edson Sardella, Paulo Noronha Lisboa-Filho, Andre Luiz Malvezzi
In the present paper we develop an algorithm to solve the time dependent Ginzburg-Landau (TDGL) equations, by using the link variables technique, for circular geometries. In additi…
