Nonlocal Particles as Strings
Tai-Chung Cheng, Pei-Ming Ho, Tze-Kei Lee
We find nonlocal particle theories with two dimensional conformal symmetry, including examples equivalent to the bosonic open string and closed string. This work provides a new app…
Pulse-duration dependence of high-order harmonic generation with coherent superposition state
Bingbing Wang, Taiwang Cheng, Xiaofeng Li +3
We make a systematic study of high-order harmonic generation (HHG) in a He-like model ion when the initial states are prepared as a coherent superposition of the ground state a…
Perturbative Approach to Higher Derivative Theories with Fermions
Tai-Chung Cheng, Pei-Ming Ho, Mao-Chuang Yeh
We extend the perturbative approach developed in an earlier work to deal with Lagrangians which have arbitrary higher order time derivative terms for both bosons and fermions. This…
Perturbative Approach to Higher Derivative and Nonlocal Theories
Tai-Chung Cheng, Pei-Ming Ho, Mao-Chuang Yeh
We review a perturbative approach to deal with Lagrangians with higher or infinite order time derivatives. It enables us to construct a consistent Poisson structure and Hamiltonian…
