Efficient Broadband Terahertz Generation from Organic Crystal BNA Using Near Infrared Pump
Hang Zhao, Yong Tan, Tong Wu +5
We are reporting on terahertz generation from organic crystal BNA using a 1.15 to 1.55 um near infrared pump. We observed a very large emission spectrum extending up to 7 THz, comp…
Possible phonon-induced electronic bi-stability in VO for ultrafast memory at room temperature
Cédric Weber, Swagata Acharya, Brian Cunningham +9
VO is a model material system which exhibits a metal to insulator transition at 67C. This holds potential for future ultrafast switching in memory devices, but typica…
Observation of Terahertz Radiation via the Two-Color Laser Scheme with Uncommon Frequency Ratios
L. -L. Zhang, W. -M. Wang, D. Wu +6
In the widely-studied two-color laser scheme for terahertz (THz) radiation from a gas, the frequency ratio of the two lasers is usually fixed at 1:2. We investigate THz g…
Parity oscillations and photon correlation functions in the Dicke model at a finite number of atoms or qubits
Yu Yi-Xiang, Jinwu Ye, CunLin Zhang
In this work, by using the strong coupling expansion and exact diagonization (ED), we study the Dicke model with independent rotating wave (RW) coupling and coun…
Photon Berry phases, Instantons, Schrodinger Cats with oscillating parities and crossover from to limit in cavity QED systems
Yu Yi-Xiang, Jinwu Ye, W. M. Liu +1
In this work, we study the Dicke model at a finite by using the expansion and exact diagonization. This model includes the four standard quantum optics m…
Comments on "Controlling Discrete and Continuous Symmetries in Superradiant Phase Transitions with Circuit QED Systems "
Yu Yi-Xiang, Jinwu Ye, W. M. Liu +1
Recently, the authors of the commented PRL presented the solution of the Dicke model studied by us previously. Here we point out that (1) The authors miss…
Super-radiance, Berry phase, Photon phase diffusion and Number squeezed state in the Dicke (Tavis-Cummings) model
Jinwu Ye, CunLin Zhang
Recently, strong coupling regimes of superconducting qubits or quantum dots inside a micro-wave circuit cavity and BEC atoms inside an optical cavity were achieved experimentally.…
