Thermal ions in spherical tokamaks have two adiabatic invariants: the magnetic moment and the longitudinal invariant. For hot ions, variations in magnetic-field strength over a gyro period can become sufficiently large to cause breakdown of the adiabatic invariance. The magnetic moment is more sensitive to perturbations than the longitudinal invariant and there exists an intermediate regime, su...

We present a general approach to the modelling of the brightness and polarization structures of adiabatic, decelerating relativistic jets, based on the formalism of Matthews & Scheuer (1990). We compare the predictions of adiabatic jet models with deep, high-resolution observations of the radio jets in the FR I radio galaxy 3C 31. Adiabatic models require coupling between the variations of velo...

Adiabatic vacua are known to be Hadamard states. We show, however that the energy-momentum tensor of a linear Klein-Gordon field on Robertson-Walker spaces developes a generic singularity on the initial hypersurface if the adiabatic vacuum is of order less than four. Therefore, adiabatic vacua are physically reasonable only if their order is at least four. A certain non-local large momentum exp...

The Energy dissipation in conventional CMOS circuits can be minimized through adiabatic technique. By adiabatic technique dissipation in PMOS network can be minimized and some of energy stored at load capacitance can be recycled instead of dissipated as heat. But the adiabatic technique is highly dependent on parameter variation. The intension of the paper is to implement combinational and sequ...

We reveal universal dynamical scaling behavior across adiabatic quantum phase transitions in networks ranging from traditional spatial systems (Ising model) to fully connected ones (Dicke and Lipkin-Meshkov-Glick models). Our findings, which lie beyond traditional critical exponent analysis and adiabatic perturbation approximations, are applicable even where excitations have not yet stabilized ...

A previous theory for studying the distribution of non-uniform fields in multiple-quantum-well photodetectors under an ac voltage is generalized by including non-adiabatic space-charge-field effects. Numerical calculations indicate that field-domain effects are only important at high temperatures or high voltages when both injection and sequentialtunneling currents are significant. On the other...

The adiabatic manipulation of quantum states is a powerful technique that opened up new directions in quantum engineering--enabling tests of fundamental concepts such as geometrical phases and topological transitions, and holding the promise of alternative models of quantum computation. Here we benchmark the stimulated Raman adiabatic passage for circuit quantum electrodynamics by employing the...

Data collected in situ with the Meteo-France Merlin-IV instrumented aircraft during the EUCREX mission 206 are analyzed to document cloud properties that are relevant to the calculation of cloud radiative properties. Ascents and descents through the cloud layer reveal that Ž . most of the vertical profiles of liquid water content LWC and droplet sizes are close to adiabatic profiles. Analysis o...

The novel design of various adiabatic adders based on pass transistor logic is introduced. Also, a new I-bit full adder basic cell with a small number of transistors is designed. The architectural design of each adiabatic adder and new formulas for their corresponding delay, are presented. The performance of various adiabatic adders, in this work, against the performance of theirs CMOS counterp...
