Non-Noether Symmetries and Lutzky Conserved Quantities for Mechanico-Electrical Systems
Mechanico-electrical system Non-Noether symmetry Lutzky conserved quantity
2012/8/7
We apply the non-Noether symmetry theory for mechanical systems to Lagrange–Maxwell mechanico-electrical systems. For these systems,
we derive the Lutzky conserved quantities from the corresponding e...
Effective Non-Hermitian Hamiltonians for Studying Resonance Statistics in Open Disordered Systems
Non-Hermitian Hamiltonians Studying Resonance Statistics
2010/12/27
We briefly discuss construction of energy-dependent effective non-hermitian hamiltonians for studying resonances in open disordered systems
Fast Converging Path Integrals for Time-Dependent Potentials II: Generalization to Many-body Systems and Real-Time Formalism
Fast Converging Path Integrals Time-Dependent Potentials II
2010/12/27
Based on a previously developed recursive approach for calculating the short-time expansion of the propagator for systems with time-independent potentials and its time-dependent generalization for sim...
van't Hoff-Arrhenius Analysis of Mesoscopic and Macroscopic Dynamics of Simple Biochemical Systems: Stochastic vs. Nonlinear Bistabilities
van't Hoff-Arrhenius Analysis Mesoscopic Macroscopic Dynamics
2010/11/16
Multistability of mesoscopic, driven biochemical reaction systems has implications to a wide range of cellular processes. Using several simple models, we show that one class of bistable chemical syste...
Sliding Mode Control of Two-Level Quantum Systems
Sliding Mode Control Two-Level Quantum Systems
2010/10/18
This paper proposes a robust control method based on sliding mode design for two-level quantum
systems with bounded uncertainties. An eigenstate of the two-level quantum system is identified as a sli...
Stationary states and fractional dynamics in systems with long range interactions
Stationary states fractional dynamics long range interactions
2010/4/7
Dynamics of many-body Hamiltonian systems with long range interactions is studied, in the context of the so called $\alpha-$HMF model. Building on the analogy with the related mean field model, we con...
Synchronization of Spatially Extended Chaotic Systems with Asymmetric Coupling
Extended Chaotic Systems Asymmetric Coupling
2010/10/13
In this paper, we report the consequences induced by the presence of asymmetries in the coupling scheme on the synchronization process of a pair of one-dimensional complex fields obeying Complex Ginzb...
Self-induced decoherence formalism and the corresponding classical limit are extended from quantum integrable systems to non-integrable ones.
Evolution, Ageing and Speciation: Monte Carlo Simulations of Biological Systems
Monte Carlo Simulations Biological Systems
2010/10/26
We present a complete description of the Penna bit-string model for biological ageing and how it has been modified, along the last 10 years, to simulate and better understand many different evolutiona...
Realizations of the osp(2,1) Superalgebra and Related Physical Systems
osp(2,1) Superalgebra Physical Systems
2010/4/12
Eigenvalues and eigenfunction of two-boson 2 \times 2 Hamiltonians in the framework of the superalgebra osp(2,1) are determined by presenting a similarity transformation. The Hamiltonians include two ...
A New Formalism for Nonextensive Physical Systems: Tsallis Thermostatistics
Nonextensive Physical Tsallis Thermostatistics Boltzmann-Gibbs
2010/4/16
Although Boltzmann-Gibbs (BG) statistics provides a suitable tool which enables us to handle a large number of physical systems satisfactorily, it has some basic restrictions : (i) the range of the mi...
