Adiabatic pulses are sometimes considered to be mysterious and exotic entities which are difficult to understand, complex to generate and impractical to implement. This work is an attempt to bring familiarity and to fulfill the preliminary needs of anyone interested in learning more about this subject. The response of magnetization to stimuli produced by adiabatic pulses is analyzed using vecto...

Adiabatic shear banding during high speed machining is important to understand material removal mechanisms. This paper investigates the microstructure of adiabatic shear bands (ASBs) in the serrated chips produced during the high speed machining of AISI 1045 hardened steel. Optical microscope, scanning electronic microscope(SEM) and transmission electronic microscope(TEM) were used to explore t...

In this paper, the authors propose a novel static random access memory (SRAM) that employs the adiabatic logic principle. To reduce energy dissipation, the proposed adiabatic SRAM is driven by two trapezoidal-wave pulses. The cell structure of the proposed SRAM has two high-value resistors based on a p-type metal-oxide semiconductor transistor, a cross-coupled n-type metal-oxide semiconductor (...

In this paper, we describe adiabatic Vedic multiplier using efficient charge recovery logic (ECRL) and energy efficient adiabatic logic (EEAL). In today’s world low power hindrance have become a major important factor in modern VLSI design. Because of the increasingly draconian demands for battery space and weight in portable multimedia devices, energy productive and high yielding circuits are ...

We present an efficient scheme to quickly generate three-qubit Greenberger–Horne–Zeilinger (GHZ) states by using three superconducting qubits (SQs) separated by two coplanar waveguide resonators (CPWRs) capacitively. The scheme is based on quantum Zeno dynamics and the approach of transitionless quantum driving to construct shortcuts to adiabatic passage. In order to highlight the advantages, w...

For the internal dynamics of molecules it is of crucial importance that nuclei are much heavier than electrons. This leads to the adiabatic picture of the nuclei motion with respect to the motion of electrons. In the adiabatic picture, the coordinates of nuclei play the role of external parameters with respect to the state of the electronic sub-system, that is they play the same role as the adi...

Extensive research is carried-out worldwide to design energy-efficient adiabatic circuits for such biomedical and space applications where conventional energy is limited and speed is not critical. In this paper a new single phase adiabatic or energy recovery logic is proposed and extensively analyzed the energy performance with technology scaling. We present a comparative study among proposed l...

We study periodic well-to-well flopping of rubidium atoms in one-dimensional grey optical lattices using a nondestructive, real-time measurement technique and quantum Monte Carlo wavefunction simulations. The observed flopping rates as well as flopping rates extracted from exact band structure calculations can largely be reproduced using adiabatic models that employ the Born–Oppenheimer approxi...

The conventional formulation of the non-adiabatic (Aharonov-Anandan) phase is based on the equivalence class {eiα(t)ψ(t, ~x)}. This equivalence class when understood as defining generalized rays in the Hilbert space is not generally consistent with the superposition principle in interference and polarization phenomena. The hidden local gauge symmetry, which arises from the arbitrariness of the ...

The adiabatic limit refers to the geometric degeneration in which the metric is been blown up along certain directions. The study of the adiabatic limit of geometric invariants is initiated by E. Witten [39], who relates the adiabatic limit of the η-invariant to the holonomy of determinant line bundle, the so called “global anomaly”. In this case the manifold is fibered over a circle and the me...
