The spin structure function of the neutron gn1 has been determined over range 0.03<x<0.6 at an average Q2 2 (GeV/c)2 by measuring asymmetry in deep inelastic scattering polarized electrons from a 3He target energies between 19 and 26 GeV. integral is found to be F10gn1(x)dx=-0.022±0.011. Earlier reported proton results together with Bjorken sum rule predict F10gn1(x)dx=-0.059±0.019.Received 1 April 1993DOI:https://doi.org/10.1103/PhysRevLett.71.959©1993 American Physical Society
We propose a scheme to generate nonreciprocal entanglement between an yttrium iron garnet (YIG) sphere and two nitrogen-vacancy-center ensembles by magnon Kerr effects in transmission-line resonator. By driving the YIG appropriately, strong nonlinearities emerge then induce parametric amplification frequency shift, resulting appearance of optimal entanglements. Depending on direction bias magnetic field, macroscopic is realized this all-solid-state quantum system, which may find potential...

In this paper, we propose a quantum interference mediated control of switching between magnon-atom entanglement and magnon blockade. A three-level $\mathrm{\ensuremath{\Lambda}}$ configuration atomic ensemble yttrium iron garnet sphere are simultaneously coupled to microwave cavity mode through magnetic dipole interaction. By applying two strong fields drive the atoms, resonant coupling dressed-state transition mode, without direct interaction, is established by adiabatically eliminating...
We propose a scheme to generate remote asymmetric Einstein-Podolsky-Rosen (EPR) steering of two magnon modes in hybrid ferromagnet-superconductor system. In our scheme, the indirect coherent coupling between distant magnons and $\mathrm{\ensuremath{\Delta}}$-type superconducting atom is established via exchange virtual photons dispersive cavities. As consequence, artificial acting as reservoir can produce asymmetrical magnon-magnon single dissipation channel. Interestingly, we find that...
Given the inevitable hypoxia and reperfusion injury that occur in organs donated after circulatory death (DCD), quality function of these are significantly compromised, greatly limiting their application clinical organ transplantation. Recently, advancement functional omics technologies has enabled us to deeply analyze mechanisms underlying DCD donor damage from multiple perspectives. This review systematically integrates studies transcriptomics, proteomics, metabolomics reveal key...
We propose a scheme of atom localization based on the interaction in $\ensuremath{\Lambda}$ configuration with strong bichromatic coupling field and weak probe equal frequency difference. One components is standing-wave field, which imposes position information Rabi frequency. By varying difference between relative phases two fields, localized either half-wavelength regions 50% probability provided population upper state detected.
In general, a magnon does not interact directly with an atom. Here we present scheme to generate coherent coupling between two magnons and superconducting artificial atom via exchange of virtual photons in dispersive cavities. By probing into the induced magnon-atom interactions, identify two-magnon process, which causes almost perfect two-mode squeezing entanglement for specific conditions. The quantum modes massive ferrimagnets survives at steady state represents genuinely macroscopic...

The single atom dispersively coupled with two microwave cavities, one of which simultaneously couples yttrium iron garnet (YIG) sphere via magnetic dipole interaction. Based on virtual photon exchange, indirect magnon-atom interaction established flexibly...
We report on the demonstration of a pure Kerr-lens mode-locked Yb:CALYO laser which can directly deliver sub-200 fs pulses with more than 20-W average power. With an incident pump power 89 W, 153-fs were generated 21.5 W at repetition rate 77.9 MHz. The corresponding peak and single pulse energy 1.6 MW 0.27 µJ, respectively. stable operation mode-locking was confirmed by very small fluctuations in both spectrum output recorded over hour. Second harmonic generation (SHG) conducted 59%...
We show that it is possible to obtain perfect higher-order squeezing via strong nonlinearities in the microwave-modified electromagnetically induced transparency (EIT). In a typical $\mathrm{\ensuremath{\Lambda}}$ three-level system coupled control field and microwave field, nonlinearity existent under full-resonant conditions can be effectively controlled by relative intensity of optical fields. Via dressed-state Bogoliubov mode transformation, we explore internal closely related parameter...
We show that the trichromatic manipulation of absorption spectrum leads to sub-half-wavelength atom localization. In particular, a three-level in Λ configuration is considered, which one transition coupled by field with sideband component being standing-wave while other probed weak monochromatic field. By varying sum relative phases components central component, localized either two half-wavelength regions 50% detecting probability when measured.
Abstract We propose a new scheme to prepare macroscopic entanglement between two rotating mirrors using dissipative atomic reservoir in double-Laguerre–Gaussian-cavity system. The two-level system driven by strong field, acts as single pathway of Bogoliubov dissipation push the original cavity modes into desirable entangled state under near-resonant conditions. Successively, photon–photon can be transferred mirror–mirror through exchange orbital angular momentum. In essence, is originated...

In addition being property that characterizes cascade \ensuremath{\mu}${\mathrm{\ensuremath{-}}}^{3}$He system, ${\mathit{P}}_{\mathrm{\ensuremath{\mu}}}^{\mathit{N}}$ is practical...
The BaMgF4 single crystal is grown by Bridgman method. third-order nonlinear refractive indices along three crystallographic axes are determined Z-scan technique with femtosecond laser. largest one that has a value of 2.35×10−18 m2/W the c-axis and corresponding susceptibility 1.24×10−12 esu. This compared LiNbO3 through self-phase modulation effect. Furthermore, mechanism possible applications relatively large also discussed at last.
We report an experimental study of atomic coherence and interference in a three-level $\ensuremath{\Lambda}$ system cold Rb atoms driven by multicolor coupling probe fields. The fields open multiple channels for two-photon Raman process. Interference between the leads to rich spectral features can be controlled phase field. constructive-interference-induced transparency or destructive-interference-induced absorption with subnatural linewidth selectively created near resonance.
The three independent second-order nonlinear optical coefficients of BaMgF4 are determined by the Maker fringe method with a nanosecond pulsed Nd:YAG laser at 1064 nm wavelength. All results relative to reference crystal congruent LiNbO3. largest element in matrix is d32, value 0.36 pm/V.
Einstein–Podolsky–Rosen (EPR) steering as a form of quantum correlation lies between entanglement and Bell nonlocality exhibits an inherent asymmetry two observers. We study EPR fields, which are generated via four-wave mixing processes entangled with each other due to the dissipation atomic reservoir. It is shown that one-way happens from one mode for different cavity decay rates not too small cooperation parameters. Depending on adiabatic nonadiabatic conditions, occurs in detuning region...

A diode pumped Kerr-lens mode-locked femtosecond Yb:LSO laser is experimentally demonstrated for the first time. The 54 fs pulses at central wavelength of 1052 nm with a bandwidth 22.5 are obtained repetition rate 113 MHz. To best our knowledge, this shortest pulse duration ever produced from Yb-doped orthosilicates lasers family.
We present a cavity dissipation scheme to prepare hybrid system of an atomic ensemble and moving mirror in squeezed entangled states. This is based on four-wave mixing the atoms radiation pressure mirror, both which combine lead Bogoliubov interactions with fields. Under adiabatic conditions, fields cause modes evolve into vacuum states, correspond two-mode The dependence entanglement parameters also presented beyond interactions.
In this paper we investigate the dispersive and absorptive properties of a system three-level cascade atoms driven by strong coherent field. Three characteristic features are found. First, for same set atom-light interaction parameters, indices refraction large at three different frequencies where absorption vanishes. These determined resonance transition between dressed states produced driving Second, negative dispersion without absorption, which leads to superluminal light propagation, is...
