Frequency-doubled scattering of symmetry-breaking surface-state electrons on liquid Helium
Miao Zhang, Wenzhi Jia, Lianfu Wei
Any systems with symmetry-breaking eigenstates can effectively radiate photons with doubled frequency of the incident light, which is known as the second harmonic generation. Here,…
Tunable one-dimensional microwave emissions from cyclic-transition three-level atoms
W. Z. Jia, L. F. Wei, Z. D. Wang
By strongly driving a cyclic-transition three-level artificial atom, demonstrated by such as a flux-based superconducting circuit, we show that coherent microwave signals can be ex…
Vacuum induced Berry phases in single-mode Jaynes-Cummings models
Yu Liu, L. F. Wei, W. Z. Jia +1
Motivated by the work [Phys. Rev. Lett. 89, 220404 (2002)] for detecting the vacuum-induced Berry phases with two-mode Jaynes-Cummings models (JCMs), we show here that, for a param…
Distinguishing left- and right-handed molecules by two-step coherent pulses
W. Z. Jia, L. F. Wei
Chiral molecules with broken parity symmetries can be modeled as quantum systems with cyclic-transition structures. By using these novel properties, we design two-step laser pulses…
Gain without inversion in quantum systems with broken parities
W. Z. Jia, L. F. Wei
For a quantum system with broken parity symmetry, selection rules can not hold and cyclic transition structures are generated. With these loop-transitions we discuss how to achieve…
