2014 The shape of the E.P.R. line 0394MS : |5 2| ~ |7 2| for the Gd3 +-n.n.n. V(Br-) centre, can be consistently interpreted by assuming a modulated rotation around the c crystal axis of the Th-Br bonds as an essential component of the displacement field in the incommensurate phase. The sensitivity of the local Gd3+ probe arises from the high value of the fourth order parameter b44 linked to th...

In electronic topological Dirac semimetals (DSMs) the conduction and valence bands touch at discrete points in the Brillouin zone and formDirac cones. They are robust against spin–orbit interaction (SOI) and protected by crystal symmetries. They can be driven to different topological phases by breaking the symmetries. In the low-temperature quantummagnetic systems themagnon dispersions have sim...

A method for building a squeezed vacuum state laser with zero diffusion from cavity losses is proposed. The results the introduction of particular reservoir engineering technique into theory, construction an effective atom-field interaction. By isomorphism between field operators in both and Jaynes–Cummings interactions, equations are then derived directly conventional theory. distinctive chara...

Positronium (Ps), a bound state of an electron and a positron, forms in various dielectric crystals [1]. Being a light impurity atom in a crystal lattice, Ps is extremely sensitive to its local surroundings and phonon lattice vibrations. In crystal lattices of non-cubic symmetry, the Ps atom may exhibit effective quadrupole interactions even in spite of the fact that it is completely electroneu...

We numerically investigate the stabilization mechanisms of skyrmion crystals under thermal fluctuations and external magnetic field in itinerant centrosymmetric tetragonal magnets. By adopting an efficient steepest descent method with a small computational cost, we systematically construct field–temperature phase diagrams effective spin model derived from electron on two-dimensional square latt...
