“…These can be magnetic nanomolecules or magnetic nanoclusters. To some extent, the consideration is applicable to dipolar and spinor trapped atoms [17][18][19][20][21][22][23] and to magnetic graphene (graphene with magnetic defects) [24,25]. Quantum dots in many aspects are similar to nanomolecules [26] and also can possess magnetization [27][28][29][30] that could be governed.…”

A method is advanced allowing for fast regulation of magnetization direction in magnetic nanosystems. The examples of such systems are polarized nanostructures, magnetic nanomolecules, magnetic nanoclusters, magnetic graphene, dipolar and spinor trapped atoms, and quantum dots. The emphasis in the paper is on magnetic nanomolecules and nanoclusters. The method is based on two principal contrivances: First, the magnetic sample is placed inside a coil of a resonant electric circuit creating a feedback field, and second, there is an external magnetic field that can be varied so that to dynamically support the resonance between the Zeeman frequency of the sample and the natural frequency of the circuit during the motion of the sample magnetization. This method can find applications in the production of memory devices and other spintronic appliances.

“…The physics of the BCS-BEC crossover in quantum condensates in particular real space or k space spots widely studied in ultracold gases is now emerging as a generic feature in multiple condensates superconductors [70][71][72][73][74][75][76]. Understanding the emergence of novel spin-orbital phases [77] is now recognized to be a key ingredient for understanding high temperature superconductors and the advances in this field are now pushing the developments of spintronics and new quantum electronics [78][79][80][81][82][83]. The isotope coefficient in the superconducting critical temperature is predicted to be independent on the variation of the chemical potential in the BCS single band theory.…”

The presence of two components in the electron fluid of high temperature superconductors and the complex charge and lattice inhomogeneity have been the hot topics of the international conference of the superstripes series, Superstripes 2015, held in Ischia in 2015. The debate on the mechanisms for reaching room temperature superconductors has been boosted by the discovery of superconductivity with the highest critical temperature in pressurized sulfur hydride. Different complex electronic and structural landscapes showing up in superconductors, which resist to the decoherence effects of high temperature, have been discussed. While low temperature superconductors described by the BCS approximation are made of a single condensate in the weak coupling the high temperature superconductors are made of coexisting multiple condensates (in different spots of the k--space and the real space) some in the BCS--BEC crossover regime and others in the BCS regime. The role of "shape resonance" in the exchange interaction between these different condensates, like "the Fano--Feshbach resonance" in ultracold gasses, is emerging as a key term for high temperature superconductivity.
