Adiabatic logic style is Proving to be an attractive solution for low power digital design. The paper investigates low – power characteristics of complementary pass -transistor logic (CPL) circuits using AC power supply. The two-phase power-clock scheme is more suitable for the design of flip-flops and sequential circuits because it uses fewer transistors. The Adiabatic flip-flop have large ene...

We prove an adiabatic theorem for the ground state of the Dicke model in a slowly rotating magnetic field and show that for weak electron-photon coupling , the adiabatic time scale is close to the time scale of the corresponding two level system–without the quantized radiation field. There is a correction to this time scale which is the Lamb shift of the model. The photon field affects the rate...

We state and prove a generalized adiabatic theorem for Markov chains and provide examples and applications related to Glauber dynamics of the Ising model over Zd/nZd. The theorems derived in this paper describe a type of adiabatic dynamics for `(R+) norm preserving, time inhomogeneous Markov transformations, while quantum adiabatic theorems deal with `2(Cn) norm preserving ones, i.e. gradually ...

We investigate adiabatic evolution of quantum states as governed by the nonlinear Schrödinger equation and provide examples of applications with a nonlinear tunneling model for Bose-Einstein condensates. Our analysis not only spells out conditions for adiabatic evolution of eigenstates but also characterizes the motion of noneigenstates which cannot be obtained from the former in the absence of...

I revisit the question of the adiabaticity of initial conditions for cosmological perturbations in view of the 3–year WMAP data. I focus on the simplest alternative to pure adiabatic conditions, namely a superposition of the adiabatic mode and one of the 3 possible isocurvature modes, with the same spectral index as the adiabatic component. I discuss findings in terms of posterior bounds on the...

Adiabatic circuit techniques have lately been a topic of interest in the low-power design community, but nobody has yet designed a complete computer using only adiabatic logic. We have (almost) completed the circuit design and layout of a simple fully-adiabatic processing element (PE) that nevertheless comprises a general-purpose parallel processor when tiled in large arrays. This PE implements...

Hybrid adiabatic potentials are considered in the framework of the QCD string model. The einbein field formalism is applied to obtain the large-distance behaviour of adiabatic potentials. The calculated excitation curves are shown to be the result of interplay between potential-type longitudinal and string-type transverse vibrations. The results are compared with recent lattice data.
