Non-adiabatic perturbations in multi-component perfect fluids
Non-adiabatic perturbations multi-component perfect fluids
2010/12/20
Еvolution of non-adiabatic perturbations in models with multiple coupled perfect fluids with
non-adiabatic sound speed is considered. Instead of splitting the entropy perturbation on relative and int...
AC square-wave, sawtooth-wave, and triangle-wave fields driven adiabatic quantum pumps in nanowire structures
AC square-wave sawtooth-wave triangle-wave fields driven adiabatic quantum pumps
2010/11/18
A dc current can be pumped through a nanostructure by two out-of-phase ac driving fields.
In this approach, we explore the pumped current properties driven by square-wave, sawtoothwave,
and triangle...
Adiabatic quantum state transfer in non-uniform triple-quantum-dot system
Adiabatic quantum state transfer non-uniform triple-quantum-dot system
2010/11/5
We introduce an adiabatic quantum state transfer scheme in a non-uniform coupled triple-quantum-dot system. By adiabatically varying the external gate voltage applied on the sender and receiver, the e...
Fluctuations in classical adiabatic processes: A general description and the emergence of a classical geometric angle
classical adiabatic processes general description classical geometric angle
2010/10/27
The intrinsic dynamical fluctuations neglected by the conventional classical adiabatic theorem
are described by a general differential equation. As a simple application, it is found that the
dynamic...

A sufficient condition validity quantum adiabatic theorem
2010/10/29
In this paper, we attempt to give a sufficient condition of guaranteeing the validity of the proof of quantum adiabatic theorem. The new sufficient condition can clearly remove the inconsistency and c...

Quantum adiabatic theorem Integral formalism Differential formalism
2010/10/29
In this paper, we note that there are two different types of inconsistencies of quantum adiabatic theorem in work of K. P. Marzlin and B. C. Sanders [Phys. Rev. Lett. 93, 160408, 2004], MS inconsisten...
Stimulated Raman adiabatic passage into continuum

2010/10/29
We propose a technique which produces nearly complete ionization of the population of a discrete state coupled to a continuum by a two-photon transition via a lossy intermediate state whose lifetime i...
Different Adiabatic Quantum Optimization Algorithms for the NP-Complete Exact Cover and 3SAT Problems
Different Adiabatic Quantum Optimization Algorithms the NP-Complete Exact Cover 3SAT Problems
2010/10/29
One of the most important questions in studying quantum computation is: whether a quantum computer can solve NP-complete problems more efficiently than a classical computer? In 2000, adiabatic quantu...
In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator wo...
Cosmological Adiabatic Geometric Phase of a Scalar Field in a Bianchi Spacetime
Cosmological Adiabatic Geometric Phase Scalar Field
2010/4/15
A two-component formulation of the Klein-Gordon equation is used to investigate the cyclic and noncyclic adiabatic geometric phases due to spatially homogeneous (Bianchi) cosmological models. It is sh...

Adiabatic Coupling Bose Gas Finite Temperatures
2010/10/15
We develop a general theory of adiabatic output coupling from trapped, weakly-interacting,
atomic Bose-Einstein Condensates at finite temperatures. For weak coupling, the output rate from the condens...
