Bold Diagrammatic Monte Carlo Technique: When the Sign Problem Is Welcome
Monte carlo thick line diagram unknown functions
2014/12/20
We introduce a Monte Carlo scheme for sampling a bold-line diagrammatic series specifying an unknown function in terms of itself. The range of convergence of this bold(-line) diagrammatic Monte Carlo ...
Bold diagrammatic Monte Carlo: A generic sign-problem tolerant technique for polaron models and possibly interacting many-body problems
Monte carlo feynman diagrams reforming particles breeding the particles
2014/12/20
We develop a Monte Carlo scheme for sampling series of Feynman diagrams for the proper self-energy, which are self-consistently expressed in terms of renormalized particle propagators. This approach i...
A Neural Network based Background Supression Technique applied to VHE Gamma Ray Data coming from the Crab Pulsar
Imaging Atmospheric Cherenkov Technique Flux Upper Limit
2014/12/12
In this thesis we present new results for the 99.9% confidence level flux upper limits on the pulsed VHE gamma ray signal coming from the Crab pulsar. In order to achieve optimum hadronic background s...
Calculation technique for simulation of wave and fracture dynamics in a reinforced sheet
simulation of wave fracture dynamics reinforced sheet Computational Physics
2011/7/27
Abstract: Mathematical models and computer algorithms are developed to calculate dynamic stress concentration and fracture wave propagation in a reinforced composite sheet. The composite consists of a...
Coupled-channels density-matrix approach to low-energy nuclear collision dynamics: A technique for quantifying quantum decoherence effects on reaction observables
Coupled-channels density-matrix low-energy nuclear collision dynamics reaction observables
2010/11/11
The coupled-channels density-matrix technique for nuclear reaction dynamics, which is based on the Liouville-von Neumann equation with Lindblad dissipative terms, is developed with the inclusion of fu...
Evolution of near-extremal-spin black holes using the moving puncture technique
near-extremal-spin black holes puncture technique
2010/3/18
We propose a new radial coordinate to write the Kerr metric in puncture form. Unlike the quasi-radial coordinate introduced previously, the horizon radius remains finite in our radial coordinate in th...
Primary vertex reconstruction based on the Kalman filter technique at BESⅢ
primary vertex Kalman method BESⅢ
2009/12/24
Primary vertex reconstruction is crucial to estimate the beam profile in collision experiments. We study the principle of an iterative process, called the Kalman filter method, and apply it to primary...
Influence of high frequency and moderate energy pulses on DLC deposition onto metallic substrates by magnetron sputtering technique
diamond-like carbon corrosion implantation surface characterization
2010/7/5
The deposition of Diamond-like carbon (DLC) films brings excellent mechanical, chemical, optical and electronic
properties to a large range of materials. However, a problem to be overcome is its poor...
