A simple and efficient method to create gap solitons is proposed in a spin-orbit-coupled spin-1 Bose-Einstein condensate. We find that free expansion along the spin-orbit coupling dimension can generate two moving solitons, which are identified from generalized massive Thirring model. The dynamics of be controlled by adjusting parameters.

the synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(ii) complexes are described. all five compounds have the general formula [cu2(l)4(o-r)2](cl)2 or [cu2(l)2(cl)2](cl)2, in which r = ch3 or h, l=2, 3 or 4-pyridinemethanol as l2, l3 or l4, respectively. the title compounds consist of dinuclear units with bridging methoxo groups in [cu2(l4)4(o-ch3)2](cl)2, hydro...

Hybrids of graphene and two-dimensional transition-metal dichalcogenides (TMDCs) have the potential to bring graphene spintronics to the next level. As we show here by performing first-principles calculations of graphene on monolayer MoS2, there are several advantages of such hybrids over pristine graphene. First, Dirac electrons in graphene exhibit a giant global proximity spin-orbit coupling,...

We investigate the possibility of creating directed spin-polarized currents in a two-dimensional electron gas (2DEG) subject to an inhomogeneous magnetic field and an external adiabatic driving. We thereby generalize concepts of quantum charge ratchets to the case with spin. Due to the Zeeman term in the Hamiltonian, spin-up and -down electrons experience different effective potentials, which c...

Rare-earth-doped crystals are excellent hardware for quantum storage of photons. Additional functionality of these materials is added by their waveguiding properties allowing for on-chip photonic networks. However, detection and coherent properties of rare-earth single-spin qubits have not been demonstrated so far. Here we present experimental results on high-fidelity optical initialization, ef...

In two-dimensional hole systems, the Rashba spin-orbit interaction leads to a spin-dependent momentum. A perpendicular magnetic field spatially separates holes with different spins, creating mass spectrometer for spin. Spin-resolved focussing has been used measure spin polarization from amplitude of peaks. this work, The authors show that ${k}^{3}$ form term semiconductor changes scattering rat...

A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a single hole spin trapped on a self-assembled InGaAs/GaAs quantum dot. The dot is embedded in a photodiode structure under an applied electric-field. Fast, triggered, initializati...

abstract. academic spin-offs are recognized as the main means of technology transfer, contribute to the commercialization of the results of academic research, leading to society wealth creation. academic spin-offs start with some major disadvantages related to their liability of newness, smallness and their university origination. it is been argued that academic spin-off need to strengthen thei...
