三亚国际数学论坛：Black Holes,Quantum Chaos,and Solvable Quantum Systems
三亚国际数学论坛 Black Holes Quantum Chaos Solvable Quantum Systems
2017/11/24
String theory is a consistent mathematical framework for quantum gravity, a deep question in both fundamental physics and mathematics. One of the main achievements during the past two decades is the d...
Abstract: A chaotic system under periodic forcing can develop a periodically visited strange attractor. We discuss simple models in which the phenomenon, quite easy to see in numerical simulations, ca...
On the classical limit of quantum mechanics and the threat of fundamental graininess and chaos to the correspondence principle
classical limit of quantum mechanics fundamental graininess and chaos correspondence principle
2010/10/21
The aim of this paper is to review the classical limit of Quantum Mechanics and to precise the well known threat of chaos (and fundamental graininess) to the correspondence principle. We will introduc...
The role of chaos in quantum communication through a dynamical dephasing channel
quantum communication dynamical dephasing channel
2010/4/6
In this article we treat the subject of chaotic environments with few degrees of freedom in quantum communication by investigating a conservative dynamical map as a model of a dephasing quantum channe...
In the current environment of financial distress, many governments are likely to soon become major holders of financial assets, but the policy debate focuses only on the likelihood and extent of short...
Adequate knowledge of the nature of river flow process is crucial for proper planning and management of our water resources and environment. This study attempts to detect the salient characteristics o...
We study synchronization of non-diffusively coupled map networks with arbitrary network topologies, where the connections between different units are, in general, not symmetric and can carry both posi...
The paper discusses the main ideas of the chaos theory and presents mainly the importance of the nonlinearities in the mathematical models. Chaos and order are apparently two opposite terms. The fact ...
Identification of delays and discontinuity points of unknown systems by using synchronization of chaos
synchronization of chaos address identification problems
2010/4/7
In this paper we present an approach in which synchronization of chaos is used to address identification problems. In particular, we are able to identify: (i) the discontinuity points of systems descr...
Weak Chaos and the "Melting Transition" in a Confined Microplasma System
Weak Chaos Confined Microplasma System Melting Transition
2010/4/8
We present results demonstrating the occurrence of changes in the collective dynamics of a Hamiltonian system which describes a confined microplasma characterized by long--range Coulomb interactions. ...
Probing Hamiltonian dynamics by means of the 0-1 test for chaos
Probing Hamiltonian dynamics 0-1 test chaos
2010/4/8
A recently proposed test for chaos [Gottwald G A and Melbourne I 2004 \textit{Proc. R. Soc. London A} {\bf 460} 603-611] is employed to probe the Hamiltonian dynamics of a one-dimensional anharmonic o...
Lagrangian transport and chaos in the near wake of the flow around an obstacle:a numerical implementation of lobe dynamics
Lagrangian transport near wake numerical implementation lobe dynamics
2009/11/13
In this paper we study Lagrangian transport in the near wake of the flow around an obstacle, which we take to be a cylinder. In this case, for the range of Reynolds numbers investigated, the flow is t...
Chaos in driven Alfvén systems:unstable periodic orbits and chaotic saddles
Chaos Alfvén systems unstable periodic orbits chaotic saddles
2009/11/2
The chaotic dynamics of Alfvén waves in space plasmas governed by the derivative nonlinear Schrödinger equation, in the low-dimensional limit described by stationary spatial solutions, is studied...
In quantum mechanics, Heisenberg's uncertainty principle says that these initial details – say, the position and momentum of a particle – cannot both be defined precisely. This inherent property has l...
