We theoretically propose a new method for generating intense isolated attosecond pulses during high-order harmonic generation (HHG) process by accurately controlling electron motion with a two-color laser field, which consists of an 800-nm, 4-fs elliptically polarized laser field and a 1400-nm, ~43-fs linearly polarized laser field. With this method, the supercontinua with a spectral width above 200 eV are obtained, which can support a ~15-as isolated pulse after phase compensation. Classical an

In this Letter, we focus on the theoretical analysis of the relativistic energy and angular distributions of the ejected photoelectrons during the relativistic tunnel ionization of atoms by intense, circularly polarized light. We make a small modification of the general analytical expressions for these distributions. The role of the initial momentum, the ponderomotive potential, and the Stark shift are considered. We also present the maximal angle of electron emission.

通过采用坐标变换理论和相应的数值方法，我们研究了设计具有多个窗口以与外界环境交换信息和物质的敞篷斗篷的方法。 与隐身斗篷相比，隐身斗篷具有近乎完美的隐身性能，适用于任何物体，尤其是必须与外部区域进行交流和交换物质的运动物体，从而为最近开发的隐身斗篷技术的实际应用开辟了可能性。

Active control of near-field radiative heat transfer between graphene-covered metamaterials

The response time and transmittivity of the magnetic fluid (MF) for different concentrations at room temperature were investigated in this letter. The volume fraction of the investigated sample ranged from 0.44% to 6.47%. It was found that the transmittivity decreased with increasing concentration u
