Study of nanostructures coupled with a superconducting lead via the neural-network quantum states methods.n

Original language description

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