Weak Force Measurement in Bistable Optomechanical System
One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...
متن کاملSmoothness and Weak* Sequential Compactness
If a Banach space E has an equivalent smooth norm, then every bounded sequence in E* has a weak* converging subsequence. Generalizations of this result are obtained.
متن کاملWeak Sequential Composition in Process Algebras
In this paper we study a special operator for sequential compo sition which is de ned relative to a dependency relation over the actions of a given system The idea is that actions which are not dependent intuitively because they share no common resources do not have to wait for one another to proceed even if they are composed sequentially Such a notion has been studied before in a linear time s...
متن کاملWeak Sequential Convergence in L , ( p , X )
We provide some new results on the weak convergence of sequences or nets lying in L,((T, & r), X) = L,(p, X), 1 <p < co, i.e., the space of equivalence classes of X-valued (X is a Banach space) Bochner integrable functions on the finite measure space ( r, z, I”). Our theorems generalize in several directions recent resuls on weak sequential convergence in L,(p, X) obtained by M. A. Khan and M. ...
متن کاملMeasuring Incompatible Observables Through Sequential Weak Measurements
Measurements are the very basis of Physics. In quantum mechanics they assume even a more fundamental role since observables can have undetermined values that “collapse” on a specific one only when a strong measurement (described by a projection operator) is done. Furthermore, a crucial feature of quantum measurement is that measuring one observable completely erases the information on the corre...
