Linear Damping

SummaryA study of the effect of linear damping on flutter speed is described. The energy exchange at flutter is considered in each degree of freedom of a general n-degrees-of-freedom system and an energy compatibility equation is formed. An analytical discussion of binary systems, based on the energy compatibility equation, is then presented.

In this paper, we present a scheme for implementing a multiqubit phase gate with one control qubit simultaneously controlling n target qubits in the ion-trap system. In our scheme, there is no energy exchange between the internal and external degrees of freedom in the course of operation, and the vibrational mode is only virtually excited. The system is insensitive to changes in the vibrational motion. The proposed scheme is experimentally feasible based on the present ion-trap techniques.

Internal Degrees Of Freedom

In this work a phenomenon arising from gas-wall interaction in rarefied regimes is presented and discussed. It is hypothesized that the effect of energy transfer between different modes of molecules scattered from walls can be used for demixing of different gas species. In order to study this effect, first a kinetic wall boundary model for diatomic gas molecules is devised. The model is derived by generalizing the Cercignani–Lampis gas-surface interaction kernel in order to embody the gas internal degrees of freedom (DoF). Here, opposed to the extensions of e.g. [5], energy exchange between different molecular modes are honored and thus different physical phenomena arising from inelastic gas–surface collisions can be observed.
