A theory of thermoelectric phenomena in superfluid $^4He$ is developed. It is found an estimation of the dipole moment of helium atom arising due to electron shell deformation caused by pushing forces from the side of its surrounding atoms. The corresponding electric signal generated in a liquid consisting of electrically neutral atoms by the ordinary sound waves is found extremely small. The second sound waves in superfluid $^4He$ generate the polarization of liquid induced by the relative accelerated motion of the superfluid and the normal component. The derived ratio of the amplitudes of temperature and electric polarization potential was proved to be practically temperature independent. Its magnitude is in reasonable correspondence with the experimental observations. The polarity of electric signal is determined by the sign of temperature gradient in accordance with the measurements. The problem of the roton excitations dipole moment is also discussed.
Equation of state of superfluid neutron matter and the calculation of $^1S_0$ pairing gap
本文用量子蒙特卡罗方法研究了中子物质零温状态方程，并用$ρ<0.04$ fm $^{-3}$计算了低密度区的$^1S_0$配对能隙。该系统是由一个非相对论性的核哈密顿量，包括两个-和三-核子相互作用的阿贡和厄巴纳型。这个模型的相互作用提供了非常准确的结果，在轻核的结合能的计算。相对于纯BCS理论的间隙的抑制被发现，但明显弱于其他作品，试图以近似的方式包括偏振效应。
