We propose a variational wave function to represent quantum skyrmions as bosonic
operators. The operator faithfully reproduces two fundamental features of quantum …

Inspired by the way that digital artists zoom out of the canvas to assess the visual impact of
their works, we introduce a conceptually simple yet effective metric for quantifying the clarity …

Magnetic skyrmions are vortexlike quasiparticles characterized by long lifetime and
remarkable topological properties. That makes them a promising candidate for the role of …

Manipulating entanglement, which reflects nonlocal correlations in a quantum system and
defines the complexity of describing its wave function, represents the extremely tough …

Undoubtedly, machine learning (ML) techniques are being increasingly applied to a wide
range of situations in the field of condensed matter. Amongst these techniques …

The scalar spin chirality is a three-body physical observable that plays an outstanding role
both in classical magnetism, characterizing non-co-planar spin textures, and in quantum …

Skyrmions are topological magnetic textures, mostly treated classically, studied extensively
due to their potential spintronics applications due to their topological stability. However, it …

Undoubtedly, machine learning techniques are being increasingly applied to a wide range
of situations in the field of condensed matter. Amongst these techniques, unsupervised …

A quantum description is given of nanoskyrmions in 2D textures with localised spins and
itinerant electrons, isolated or coupled to leads, in or out of equilibrium. The spin-electron …

We develop an approach for characterizing non-local quantum correlations in spin systems
with exactly or nearly degenerate ground states. Starting with linearly independent …
