STUDY OF NANOSTRUCTURES COUPLED WITH A SUPERCONDUCTING LEAD VIA THE NEURAL-NETWORK QUANTUM STATES METHODS

Popis výsledku v původním jazyce

The Neural-Network Quantum States (NNQS) method is rapidly emerging as a powerful tool for investigating quantum many-body physics. By combining variational Monte Carlo techniques with neural network-based variational functions, this approach leverages the remarkable advancements in deep learning achieved in recent years. While substantial progress has been made in simulating magnetic systems on lattices, simple molecules, and even continuous systems, the ab initio simulation of complex strongly correlated electron systems continues to pose significant challenges. With the help of the generalized atomic limit (GAL) - a recently developed model describing a system of quantum dots coupled to a superconducting lead - we attempt to show the efficiency and accuracy of NNQS, mainly the Restricted Boltzmann Machine, by comparing the acquired results to other available methods such as exact diagonalization. The simultaneous study of the system&apos;s properties such as the energy spectrum and quantum phase transitions could bring advancements in electronics, sensors or the design of high-quality qubits used in quantum computers.
