Study of Simulation Method of Time Evolution in Rigged QED
Study of Simulation Method Time Evolution Rigged QED Atomic Physics
2012/4/20
We discuss how we formulate time evolution of physical quantities in the framework of the Rigged QED (Quantum Electrodynamics). The Rigged QED is a theory which has been proposed to treat dynamics of ...
Embeddings and time evolution of the Schwarzschild wormhole
Einstein-Rosen bridge Schwarzschild wormhole embedding
2011/10/9
Abstract: We show how to embed spacelike slices of the Schwarzschild wormhole (or Einstein-Rosen bridge) in R^3. Graphical images of embeddings are given, including depictions of the dynamics of this ...
Adiabatic Theorem for Discrete Time Evolution
adiabatic theorem quantum map quantum circuit Quantum Physics
2011/10/8
Abstract: A proof of the adiabatic theorem for quantum systems whose time evolution proceeds along discrete time, e.g., quantum maps and quantum circuits, is shown.
On the space and time evolution of regular or irregular human heart or brain signals
regular or irregular human heart brain signals
2011/8/29
A coupled map is suggested to investigate various spatial or temporal designs in biology: Several cells (or tissues) in an organ are considered as connected to each other in terms of some molecular di...
A commonly adopted relational account of time evolution in generally-covariant systems, and more specifically in quantum cosmology, is argued to be unsatisfactory, insofar as it describes evolution re...

Non-equilibrium time evolution of bosons from the functional renormalization group
Non-equilibrium time evolution of bosons functional renormalization group
2010/11/25
We develop a functional renormalization group approach to obtain the time evolution of the
momentum distribution function of interacting bosons out of equilibrium. Using an external outscattering rat...
Macroscopic time evolution and MaxEnt inference for closed systems with Hamiltonian dynamics
MaxEnt algorithm information theory statistical mechanics Hamiltonian dynamics
2010/11/24
MaxEnt inference algorithm from the information theory is relevant for the time evolution of macroscopic systems which represents a problem of incomplete information. Two different approaches using Ma...
Time-Evolution of a Fractal Distribution: Particle Concentrations in Free-Surface Turbulence
Fluid Dynamics (physics.flu-dyn) Chaotic Dynamics (nlin.CD)
2010/11/11
Steady-state turbulence is generated in a tank of water and the trajectories of particles forming a compressible system on the surface are tracked in time. The initial uniformly distributed floating p...
Dirac neutrino magnetic moment and a possible time evolution of the neutrino signal from a supernova
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Phenomenology (hep-ph)
2010/12/23
We analyze the influence of neutrino helicity conversion, $\nu_L \to \nu_R$, on the neutrino flux from a supernova caused by the interaction of the Dirac neutrino magnetic moment with a magnetic field...
Time evolution of Wigner functions governed by bipartite Hamiltonian system with kinetic coupling
entangled Wigner operator Wigner function evolution entangled state representation
2010/6/30
For the bipartite Hamiltonian system with kinetic coupling, we derive time evolution equation of Wigner functions by virtue of the bipartite entangled state representation and entangled Wigner operato...
