Authors: LI GUANG-YI  , GUO HAN-YING  ,   (1)苏州大学物理系; (2)中国科学院理论物理研究所
Published: December 2020

Following the procedure to transmute the relativistic theory of classical particles to quantum theory in the Minkowski spacetime, we have proposed a scheme to establish relativistic wave equations for scalar particles and spinor particles in the Beltrami-de Sitter spacetime. It is shown that these equations are invariant under the transformations of the de Sitter group and are just the Klein-Gordon equation and the Dirac equation in the Beltrami-de Sitter spacetime respectively. The eigenfunctions and the corresponding discrete eigenvalues of these equations on the metric of a family of space-like simultaneous hypersurfaces in the Beltrami-de Sitter spacetime have been obtained.

Published: December 2020

Based on the results of the previous paper [1], the dynamic aberration correetion in a combined scanning electron beam system is studied. The possibility of dynamic aberration correction by using electro-magnetic multipole fields is discussed. The formulas for calculating aberrations, caused by round and multipole correctors, are derived.Thus we show that in a combined scanning electron beam system most of the third order deflection aberrations may be eliminated by properly using a dynamic aberration correction system, consisting of round lens, deflector and quadrupole devices.

SOFT PHONON AND ITS RAMAN SCATTERING IN A CHARGE-DENSITY-WAVE SUPERCONDUCTOR
Authors: LEI XIAO-LIN  ,   中国科学院上海冶金研究所
Published: December 2020

Following the idea put forward by Balseiro and Falicov, we have calculated the renor-malized spectral function A (ω) of the amplitude mode of Charge-Density-wave (CDW) phonon by electron-phonon interaction in a model system with coexisting CDW and superconductivity. The A(ω) obtained shows a havily weighted peak of delta-function type at the frequency ω≤2G, where G is the CDW band gap, and a relatively broad continuous spectrum in the region ω>2(G2十△2)1/2, where △ is the superconducting energy gap. Under the condition of fixed G, as △ decreases the intensity of the peak decreases considerably with only a small shift in its position, while the weight of the continuous spectrum raises. These characteristics are in agreement with the behavior of the Raman-active gap modes found by Sooryakumar and Klein in CDW superconductor 2H-NbSe2.

The ultraviolet photoelectron spectroscopy of GaAs (100) surface (4×1) structure has been measured by using a polarized UV light source. From the differential spectra between the UPS of the clean surface and the surface with adsorbed oxygen, the surface state peak located within 2eV below valence band maximum could be identified. According to the spectra obtained with s- and p-polarized light and the selection rule of electron transition, it could be shown that this surface state cosists of three peaks: the peak at 0.5eV below valence band maximum corresponding to the bridge bond states of surface Ga atoms, the peak at 0.7eV resulting from the bridge bond states of surface As atoms, and the peak at 1.3eV related to the dangling bond states.

The second-order electron density fluctuation in homogeneous unmagnetized plasma is calculated by means of dynamical method. The third-order non-linear susceptibility resulting from interaction of three waves in plasma and the scattered power of K4=K1-K2+K3,ω4=ω1-ω2+ω3 is obtained. As compared with the normal non-coherent Thomson scattering, the scattered signal is very strong. So the coherent four-photon scattering can be taken as one of the important method in plasma diagnostics.

It was found that some processing conditions, such as forming pressure, sintering time and sintering procedure have great effect on ionic conductivity. The attention was focused on the physical origins of these effects. The best specimens could be prepared under forming pressure about 8t/cm2 and continual sintering at 1000℃ for 5 to 6 days. The temperature fluctuation should be avoided during sintering process.

Published: December 2020

The (4+1)-dimensional cosmological model discussed in this paper is a direct product of the usual 4-dimensional spacetime and a. 1-dimensional compaetified internal space. The energy density of the 4-dimensional spacetime is supposed to be dominated by incoherent radiation and the energy-momentum tensor of the internal subspace is a step function. By solving the 5-dimensional Einstein field equations without cosmolog-ical term we get the de-Sitter solution to describe the usual spacetime and at a certain time it changes to the radiation-dominated solution for standard model, and the size of the internal subspace changes with time in a form of oscillation with amplitude attenuating and then contracts to a constant.

In order to check our computer codes, we have calculated the excitation energies for N=2 states and the corresponding radiative transition rates for the atomic helium. The results of our non-relativistic and relativistic calculations agree with each other. The excitation energies are accurate within a few thousandths, the corresponding radiative transition probabilities within a few percents. Our methods can be readily applied to other atoms as well as ionized atoms.

Published: December 2020

Positron annihilation lifetime spectra and Doppler broadening linesliapes of positron annihilation radiation energy were measured for the tension-compression fatigued Ni specimens under constant strain amplitude and for the cold rolled ones which were used for comparison. A few of the formers were selected for TEM observation. A lifetime component that can be associated with e+ lifetime in vacancy clusters developed during fatigue process was resolved by using a multi-exponential fitting method. It is 209, 255 and >300 ps on average in diferent ranges of fatigue respectively. The change of its relative intensity seems associated with increase of the concentration of the small vacancy clusters at early stage and growth of its dimension afterwards.Hence, this work provides a experimental evidence for the formation and clustering of vacancies as well as the development of a great number of jogged dislocations in fatigued Ni. The concentration of these defects were estimated by using a simple three state e+ trapping model. This work also provides a illustration of the utility of multi-exponential fitting method to complex lifetime spectra and to the above mentioned trapping model.

Published: December 2020

The martensitic transformation in thirteen Fe-Ni alloys has been studied by positron annihilation technique. The experimental results show that the values of the average lifetime f and the lineshape parameter S increase by about 30% and 20% respectively in six annealed and liquid nitrogen quenched alloys (28.22-31.30 wt% Ni). This confirms that the direct transformation produces a great number of defects in these alloys. The changes of the positron parameters with treating temperature have been determined in two different martensitic substructure alloys. It has been detected that the defects are chiefly produced in the stage of the burst martensitic transformation. Two distinct stages in the isochronal annealing curve confirm that the defects formed in the direct transformation mainly consist of vacancies and dislocations.

Published: December 2020

The nonlinear behavior of ultrasonic absorption in glasses below 2 K is analysed by combining the two-level systems model and the infrared divergence theory. A modification of the existing tunneling two-level model of Jackie et al. is given. The Bloch equations are used as the macroscopic equations of the "magnetization" and all quantities in the equations as en-sebmble averages rather than a state expectation value. With this modification, and the defect state as a pseudo-spin in the local fluctuation field, the relation between the angle diffusion of the spin and the temperature at low temperatures is deduced. The theoretical absorption curve obtained is consistent with the experimental data. The observed T-0.7 rule of the resonance absorption under weak excitation and the proportional relation of the saturated absorption to ω2 are also explained.

Hall effect measurements were carried out on rf-sputtered Fe3O4 and γ-Fe2O3 thin films in magnetic field up to 1.4 T applied perpendicular to the film plane. Their ordinary and extraordinary coefficients are determined from the experimental data. The calculated values of the Hall mobilities for these two films are 2.35 and 1.56cm2/V·s respectively, which are larger than 1 cm2/V·s, suggesting the occurrence of large polaron scattering. The extraordinary Hall effects were compared by using Berger side-jumping model. The negative magnetic resistivity is also observed for these two films.

Published: December 2020

A model on the Rayleigh-Benard problem of a non-ideal MHD flow in a sheared magnetic field is proposed and studied. A new set of nonlinear differential equations for the model bas been derived. Theoretical and numerical analysis shows that the set of equations implies a strange attractor with several novel features differing from Lorenz attractor and, in particular, the coexistence of all three routes to chaos in that model. Among the well-known models with these routes, so far, our system of equations is the unique one without any extrinsic periodic driving term. It exhibits more immediately the intrinsic stochasticity of deterministic nonlinear system. The stochastic motion and reconnection of magnetic field-lines, and the creation of magnetic islands are observed in numerical simulating of this set of equations.

We have found that some bowl-like compounds can form disordered crystalline phaseswhich have long-range positional order, with strong fluctuation in position and orientation. Their side chains are in a molten state. X-ray diffraction has shown that two homologues of hexaesters of cyclotricatechylene are stacked as triclinic system with space group of Pl. The parameters of a unit cell, density of the compounds, as well as expansion coefficient are obtained. The modelling of an unit cell is presented, which confirms the up and down asymmetry in the molecules, but there is no ferroelectricity macroscopically.

Comparison of the expressions of the escape probability and the dimension in the isotropic model yields a relation between the dimensionality and the layer coupling in Y1Ba2Cu3O7. Theoretical cal ulation indicates that Y1Ba2Cu3O7 is very close to a three-dimensional systems.

Published: December 2020

The dominent factors affecting the nuclear spin relaxation of 1H in HfV2·Hx hydrides are dipolar couplings. The important theoretical problem is the calculation of spectral density functions for the fluctuation of the dipolar couplings caused by the diffusive motion of 1H in the host lattice. We extended Torrey's theory, based on the model of random walk to nearest neighbor sites for homonuclear dipolar interaction, to the case that both homo- and heteronuclear interactions are existent. Then we calculated the GHH(k, y) and GHV(k, y) for determining the spectral densities JqHH(ω) and JqHV(ω) (q = 0, 1,2) according to the structure constants and H occupations of HfV2 ·Hx obtained from neutron diffractions. Using our theory and data derived from previous work of others, we analyzed the activation energy and the attempt frequency of 1H on interstitial sites and found that our results are satisfactory as compared with the conclusion derived from the phenomenological theory.

Published: December 2020

The I-V curves of a series of possible models of Cs/C(0001)—(2×2) surface are calculated by dynamical LEED theory with RSP and RFS methods. The dalculated curves are selected with experimental results and the best structure is chosen by R-factor calculation. The model of Cs intercalating graphite layers forming intercalate structure and the model of Cs atoms adsorbed on top position of graphite surface are ruled out by R-factor examination. The most probable structure is that Cs atoms adsorbed on hollow position of graphite layer with a interlayer distance of 2.80 ? between Cs laver and graphite, and substrate has the same, structure as that of graphite bulk structure.

Published: December 2020

The electronic structures of Si (111) surface have been studied by means of molecular orbital theory of SCF-CNDO with the cluster model treatment. The calculated results show that: (1) The distribution and transfer of net charges in thesurface have localized characters at the atomic orbitals. Also, the T30, T3+ and T3-defect forms do not exist easily in practical system. (2) The electronic structures can be discribed with the stoohastic potential, from which one can find out the adsorption site and learn the adsorption dynamic process of ion and ionic molecules adsorbed on the Si (111) surface. (3) The surface states mainly appear in the region from the top of valence band to the centre of gap, and is strongly localized at the atomic orbitals. The above-mentioned results are consistent with some experimental discoveries.
ATOMIC ABSORPTION AND DISPERSION IN SQUEEZED LIGHT FIELD
Authors: ZHANG WEI-PING  , TAN WEI-HAN  ,   中国科学院上海光学精密机械研究所
Published: December 2020

In this paper, the optical Bloch equations of a two-level atom ensemble driven by squeezed light field are derived. Based on these equations, we calculate the atomic absorption and dispersion. The results show that for different squeezing conditions of the field fluctuations, atomic absorption-lineshape exhibits sub-or super-natural linewidth phenomenon. Atomic dispersion depends on the squeezing direction and coherent excitation direction of the driving field. When these two directions are not parallel or perpendicular to each other, the dispersion zero-point shows a shift to the transition frequency of the atom.

We apply the theory established in ref. [10] and the general results to treat heat fluctuations in dielectric materials, by considering the phonon heat conduction in one, two and three dimensions, as well as in metals, where we deal with electronic heat conduction. We compare our results with an exact solutions from an exact model for the nonequibrium fluctuations in a linear harmonic chain based on an information-theoretical approach. These solutions coincide reasonably. And so prove the theory presented in [10] is correct.

Published: December 2020

In this paper, the M?ssbauer spectra of amorphous Fe90-xCoxZr10 (x=4, 10, 20,…70) and Fe90-yCryZr10 (y = 0, 4, 7, 16, 20) series of alloys were studied. The experimental results indicated that, a-Fe90-yCryZr10 and a-Fe90-xCoxZr10 in Fe-rich regions contain two different local coordination structure, which produce both ferromagnetic and antiferromagnetic states below Tc and different paramagnetic states above Tc. When x is above 30, in a-Fe90-xCoxZr10 alloys exists only one ferromagnetic state, which implies magnetic "homogeneity". The micro-structures of amorphous transition metal (TM)-TM alloys were discussed in some detail.

The result was that the light isotopes are preferential ejected "normally" and the heavy ones "obliquely". The reason was considered to oe the energy and momentum asymmetry between light and heavy isotopes in the collision cascades. A simple formula of the angular distribution of isotopic sputtering which fits the experimental result is given in this paper.
