Matthew Beutel, Alexander Ahrens, Chenhang Huang, Yasuyuki Suzuki, Kalman Varga

摘要:

引入了变形相关高斯基函数,并计算了它们的矩阵元。这些基函数可以用来解决非球势问题。这种势的一个例子是Pauli-Fierz哈密顿量中的偶极自相互作用项。给出的例子表明变形高斯基函数的准确性和必要性,以精确地解决光-物质耦合系统的腔QED。

英文摘要:

Deformed correlated Gaussian basis functions are introduced and their matrix elements are calculated. These basis functions can be used to solve problems with nonspherical potentials. One example of such potential is the dipole self-interaction term in the Pauli-Fierz Hamiltonian. Examples are presented showing the accuracy and necessity of deformed Gaussian basis functions to accurately solve light-matter coupled systems in cavity QED.
