Enhancement of field squeezing using coherent feedback

Algebraic Coherent States and Squeezing

The eigenstates of general complex linear combination of SU(1, 1) generators (suc(1, 1) algebraic coherent states (ACS)) are constructed and discussed. It is shown that in the case of quadratic boson representation ACS can exhibit strong both linear and quadratic amplitude squeezing. ACS for a given Lie group algebra contain the corresponding Perelomov CS with maximal symmetry. PACS numbers: 03...

Seed Germination Enhancement of Zinnia (Zinnia elegans) Using Electromagnetic Field

The effect of electromagnetic field was examined on Zinnia (Zinnia elegans) seeds to enhance seed germination and early growth. The seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mT in four durations of 30, 60, 120 and 240 min. The experiments were carried out in two forms of laboratory germination and soil emergence. Results showed that magnetic field application enhance...

Coherent Feedback Control of Linear Quantum Optical Systems via Squeezing and Phase Shift

The purpose of this paper is to present a theoretic and numerical study of utilizing squeezing and phase shift in coherent feedback control of linear quantum optical systems. A quadrature representation with built-in phase shifters is proposed for such systems. Fundamental structural characterizations of linear quantum optical systems are derived in terms of the new quadrature representation. T...
