INFLUENCE OF THE SQUEEZED ANGLE ON THE SQUEEZING EFFECT OF MESOSCOPIC COUPLED CIRCUIT

Ji Ying

Starting from the classical motion equation of a non\|dissipative mesoscopic inductance coupled circuit with source, it investigates the fluctuations of the charge and current in the mesoscopic inductance coupled circuit at the squeezed vacuum state, and study especially the influences of the squeezed angle on the fluctuations. The results indicate if the system is in the squeezing vacuum state, the quantum fluctuations of both circuits are related reciprocally but the fluctuations are independent with the source.Also,the squeezed effect of the charge and current is depended on the squeezing parameter γ and the squeezing angle θ as well. Moreover, the fluctuation of the charge and current does not monotonously decrease in an arbitrary squeezed angle θ , instead of has a minimum. [

Quantum Effects of a Dissipative Mesoscopic Circuit with Mutual Inductance

Yinghua Ji, Yi-you Nie, Le Jian-Xin +1 more

We study the quantum fluctuations of the charge and current of two L-C dissipative mesoscopic circuit with the mutual inductance in the vacuum state. Our results show that the system state will evolve to a squeezed coherent state under the effect of external source. We find that the squeezing amplitude parameter is relative to the parameters of circuit and the mutual-inductance coefficient in the existence of dissipation. When the circuit has no dissipation or there is complete coupling between two meshes, the squeezing amplitude parameter only depends on the capacitance's ratio.

Quantum effect of mesoscopic inductance-capacitance coupled circuit with mutual inductance

Shou Zhang

The quantum effect of mesoscopic inductance-capacitance coupled circuit with mutual inductance was investigated by canonical transformation and unitary transformation. The mesoscopic inductance-capacitance coupled circuit was compared with several coupling circuits. It is found that it is convenient to control the quantum fluctuations and squeezed effect by adjusting mutual inductance coupling coefficient in mutual inductance circuit with coupling capacitance. Uncertainty relations of charges and conjugate currents are related to canonical transformation parameter φ and uncertainty relations parameter ξ. When ξ→1 or φ→nπ/2, (n = 0,1,2,…), the uncertainty relations approach minimum value h/2.

Mesoscopic complicated coupling circuit is quantized,and Hamiltonian is diagonalized by unitary transformation.The quantum fluctuations of the charge and current of each loop in the squeezed vacuum state and vacuum state are researched.The results show that quantum fluctuations are related to not only circuit device parameter,squeezed coefficients and squeezed angle,but also coupled magnitude of mutual inductance、capacitance and inductance.
