论文摘要
我们发现，两种彩色场可以通过谐振电子激发以 - $3Ω$ -PHOTON与三$ω$ -Photons方案的谐振电子激发来诱导手性分子的各向同性样品。这些永久性偶极子是对映异敏的，可以通过两种颜色之间的相对相控制。当两种颜色彼此之间是线性极化的时化时，两种途径之间的干扰会引起对分子触觉和方向敏感的激发，从而导致激发分子的单轴定位以及对对照敏感的永久性永久性偶极于极化平面。我们还发现，尽管相应的2 $2Ω$ -PHOTON与两$ω$ -PHOTONS方案无法产生对映异敏的永久性偶极子，但它可以产生对映射的永久性四极杆，也可以通过两种彩色相对阶段控制。
We find that two-color fields can induce field-free permanent dipoles in initially isotropic samples of chiral molecules via resonant electronic excitation in a one-$3ω$-photon vs. three-$ω$-photons scheme. These permanent dipoles are enantiosensitive and can be controlled via the relative phase between the two colors. When the two colors are linearly polarized perpendicular to each other, the interference between the two pathways induces excitation sensitive to the molecular handedness and orientation, leading to uniaxial orientation of the excited molecules and to an enantio-sensitive permanent dipole perpendicular to the polarization plane. We also find that although a corresponding one-$2ω$-photon vs. two-$ω$-photons scheme cannot produce enantiosensitive permanent dipoles, it can produce enantiosensitive permanent quadrupoles that are also controllable through the two-color relative phase.
