The future of topological analysis in experimental charge-density research
, 2017 In a recent paper, Dittrich (2017) critically discussed the benefits of analysing experimental electron density within the framework of the quantum theory of atoms in molecules, often called simply the topological analysis of the charge density.

The QCD topological charge and its thermal dependence: the role of the η′ [PDF]
, 2019 We analyze the contribution of the η′(958) meson in the first two non-trivial moments of the QCD topological charge distribution, namely, the topological susceptibility and the fourth-order cumulant of the vacuum energy density.

Advanced Functional Materials, EarlyView.A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Topological-charge-dependent dichroism and birefringence of optical vortices
Material anisotropy and chirality produce polarization-dependent light-matter interactions. Absorption leads to linear and circular dichroism, whereas elastic forward scattering produces linear and circular birefringence.

Generalizing "Charge without Charge" to Obtain Classical Analogs of Short-Range Interactions [PDF]
, 2007 Several decades ago, Wheeler and Misner presented a model of electric charge ("charge without charge") based on the topological trapping of electric field lines in wormholes.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives
Advanced Materials, EarlyView.Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Optics-to-THz conversion of vortex beams using nonlinear difference frequency generation [PDF]
Компьютерная оптика, 2019 In this paper, using a modified model of slowly varying amplitudes, a process of optics-to-THZ-conversion of vortex beams based on the nonlinear difference frequency generation in a medium with second-order susceptibility is considered.
