含有公共噪声的线性二次平均场社会控制——直接解耦方法
公共噪声 线性二次平均场 社会控制 直接解耦方法
2023/1/4
This paper is concerned with mean field linear quadratic social control with common noise, where the weight matrices of individual costs are indefinite We first obtain a set of forward–backward stocha...
Normal Collisions of Spheres: A Literature Survey on Available Experiments
Normal Collisions of Spheres Literature Survey Available Experiments
2012/4/19
The central collision between two solid spheres or the normal collision between a sphere and a plate are important to understand in detail before studying more complex particle interactions. Models ex...
Evolution of massive fields around a black hole in Horava gravity
Evolution of massive fields black hole Horava gravity
2010/12/20
We study the time evolution of massive scalar field in the spacetime geometry of Kehagias-
Sfetsos(KS) black hole in deformed Hoˇrava-Lifshitz(HL) gravity by numerical analysis. We find
that the sig...
Weak Pion and Photon Production off Nucleons in a Chiral Effective Field Theory
Weak Pion Photon Production off Nucleons Chiral Effective Field Theory
2011/1/7
Neutrino-induced pion and photon production from nucleons and nuclei are important for the
interpretation of neutrino-oscillation experiments, and these processes are potential backgrounds in the Min...
Noise kernel for a quantum field in Schwarzschild spacetime under the Gaussian approximation
quantum field Schwarzschild spacetime Gaussian approximation
2010/12/20
A method is given to compute the noise kernel, defined as the symmetrized con-nected 2-point function of the stress tensor, for the conformally invariant scalar field in the Hartle-Hawking state in Sc...

2010/12/20
Recently, a generally covariant reformulation of 2 dimensional flat spacetime free scalar field theory known as Parameterised Field The-ory was quantized using Loop Quantum Gravity (LQG) type ‘polymer...

These notes are an expanded version of lectures given at the Croatian School on Black Holes at
Trpanj, June 21-25, 2010. The aim is to provide a practical introduction to quantum field theory in curv...
How the Hawking effect and prepared states affect Entanglement distillability of Dirac fields
Black hole Dirac fields Entanglement distillability
2010/12/21
How the Hawking effect and the prepared states influence the entanglement distillability of Dirac fields in the Schwarzschild spacetime is studied by using the Werner states which are composed of the ...
We examine the onset of classical topological order in a nearest-neighbor kagome ice model. Using Monte Carlo simulations, we characterize the topological sectors of the groundstate using a non-local ...
Discretizations of continuum theories often do not preserve the gauge symmetry content.
This occurs in particular for diffeomorphism symmetry in general relativity, which leads to
severe difficultie...
Dynamics of systems with isotropic competing interactions in an external field: a Langevin approach
Dynamics of systems isotropic competing interactions external field: a Langevin approach
2010/11/25
We study the Langevin dynamics of a ferromagnetic Ginzburg-Landau Hamiltonian with a competing longrange repulsive term in the presence of an external magnetic field. The model is analytically solved ...
