Nonlinear Compton scattering in a quantized pump field
Kenan Qu
We develop a fully quantized theory of nonlinear Compton scattering driven by a single-mode quantum field. Exact quantum-Volkov states retain pump depletion, back-action, and final…
Nonlinear Compton scattering in a frequency-modulated field
Antonino Di Piazza, Kenan Qu
When an electron is accelerated, it emits radiation. In the relativistic quantum realm the elementary radiation process is the emission of a single photon, a process known as nonli…
Generating quadrature squeezed light with dissipative optomechanical coupling
Kenan Qu, G. S. Agarwal
The recent demonstration of cooling of a macroscopic silicon nitride membrane based on dissipative coupling makes dissipatively coupled optomechanical systems as promising candidat…
Optomechanical Ramsey Interferometry
Kenan Qu, Chunhua Dong, Hailin Wang +1
We adopt the Ramsey's method of separated oscillatory fields to study coherences of the mechanical system in an optomechanical resonator. The high resolution Ramsey fringes are obs…
Strong squeezing via phonon mediated spontaneous generation of photon pairs
Kenan Qu, G. S. Agarwal
We propose a scheme generating robust squeezed light by using double cavity optomechanical system driven by a blue detuned laser in one cavity and by a red detuned laser in the oth…
Ramsey spectroscopy with squeezed light
Kenan Qu, G. S. Agarwal
Traditional Ramsey spectroscopy has the frequency resolution , where is the time separation between two light fields. Using squeezed states and two-atom excitation joint…
Phonon mediated electromagnetically induced absorption in hybrid opto-electro mechanical systems
Kenan Qu, G. S. Agarwal
We predict the existence of the electromagnetically induced absorption (EIA) in the double cavity configurations of the hybrid opto-electro mechanical systems (OEMS). We discuss th…
Optical memories and transduction of fields in double cavity optomechanical systems
Kenan Qu, G. S. Agarwal
Using electromagnetically induced transparency we show how the opto-mechanical systems can be used both as memory elements as well as for the transduction of optical fields. We use…
Spontaneous Generation of Photons in Transmission of Quantum Fields in PT Symmetric Optical Systems
G. S. Agarwal, Kenan Qu
We develop a rigorous mathematically consistent description of PT symmetric optical systems by using second quantization. We demonstrate the possibility of significant spontaneous…
