We have studied survival and rotational excitation probabilities of H(2)(v(i) = 1, J(i) = 1) and D(2)(v(i) = 1, J(i) = 2) upon scattering from Cu(111) using six-dimensional (6D) adiabatic (quantum and quasi-classical) and non-adiabatic (quasi-classical) dynamics. Non-adiabatic dynamics, based on a friction model, has been used to analyze the role of electron-hole pair excitations. Comparison be...

Chemical reactions that occur in the ground electronic state are described well by invoking the Born-Oppenheimer approximation, which allows their development to be rationalized by nuclear rearrangements that smoothly traverse an adiabatic potential energy surface. The situation is different, however, for reactions in electronically excited states, where non-adiabatic transitions occur between ...

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...

This paper presents a novel modified comparator based on the combination of 2N-2N2P adiabatic logic and two phase adiabatic static clocked logic (2N-2N2P and 2PASCL), combination of efficient charge recovery adiabatic logic and two phase adiabatic static clocked logic (ECRL and 2PASCL). This new structure computes a decision making signal faster than the existing methods. The introduced logic b...

To account for the phenomenon of quantum decoherence of a macroscopic object, such as the localization and disappearance of interference, we invoke the adiabatic quantum entanglement between its collective states(such as that of the center-of-mass (C.M)) and its inner states based on our recent investigation. Under the adiabatic limit that motion of C.M dose not excite the transition of inner s...

This paper presents a new adiabatic circuit technique called Positive Feedback Adiabatic Logic (PFAL). Power reduction is achieved by recovering the energy in the recovery phase of the supply clock. Energy dissipation comparison with other logic circuits is performed. The main objective of this paper is to provide new low power solutions for Very Large Scale Integration (VLSI) designers. The dy...

In recent years, low power circuit design has been an important issue in VLSI design areas. If the power consumption is less, then the amount of power dissipation is also less. Energy recovery adiabatic logic circuit is a low power design solution. Adiabatic circuits are those circuits which work on the principle of adiabatic charging and discharging. These circuits recycle the energy from outp...

This paper presents the design for low power circuilts which use reversible logic to conserve energy. The project presents the implementation of a Sklansky tree adder structure using a quasi static adiabatic logic namely CEPAL (Complementary Energy Path Adiabatic Logic). The SKLANSKY Tree adder structure has been chosen due to its increased fan-out that results in reduced latency and improved s...

Test particle simulations are performed in order to analyze in detail the dynamics of transmitted electrons through a supercritical, strictly perpendicular, collisionless shock. In addition to adiabatic particles, two distinct nonadiabatic populations are observed surprisingly: (i) first, an over-adiabatic population characterized by an increase in the gyrating velocity higher than that expecte...

In this study, adiabatic temperature rise tests depending on binder type and adiabatic specimen volume were performed, and the maximum adiabatic temperature rises and the reaction factors for each mix proportion were analyzed and suggested. The results indicated that the early strength low heat blended cement mixture had the lowest maximum adiabatic temperature rise (Q∞) and the ternary blended...
