Keywords: feedforward autoencoder, low-dimensional Hilbert spaces, numerical ground-state estimation We study the applicability of feedforward autoencoders in determining the ground state of a quantum system from a noisy signal provided in a form of

We apply the method of flow equations to describe quantum systems subject to a time-periodic drive with a time-dependent envelope. The driven Hamiltonian is expressed in terms of its constituent Fourier harmonics with amplitudes that may vary as a fu

Time crystalline structures are characterized by regularity that single-particle or many-body systems manifest in the time domain, closely resembling the spatial regularity of ordinary space crystals. Here we show that time and space crystalline stru

We consider a method of sub-wavelength superlocalization and patterning of atomic matter waves via a two dimensional stimulated Raman adiabatic passage (2D STIRAP) process. An atom initially prepared in its ground level interacts with a doughnut-shap

A scheme to transfer the orbital angular momentum between two light beams with efficiency up to unity is theoretically demonstrated. The method uses a double-$\mathrm{\ensuremath{\Lambda}}$ atomic system, a pair of spatially dependent control beams,

We propose a simple scheme for the realization of a topological quasienergy band structure with ultracold atoms in a periodically driven optical square lattice. It is based on a circular lattice shaking in the presence of a superlattice that lowers t

Fractional Chern insulators are the proposed phases of matter mimicking the physics of fractional quantum Hall states on a lattice without an overall magnetic field. The notion of Floquet fractional Chern insulators refers to the potential possibilit
