Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Wormholes, Berry phases and factorization
虫洞 浆果阶段 因子分解 编码拓扑信息
2023/5/15
I shall start by reviewing the connection between the wormholes and entanglement in the context of AdS/CFT. I shall then show how the Berry phase, a geometrical phase encoding information about the to...
ENDMEMBER EXTRACTION OF HIGHLY MIXED DATA USING L1 SPARSITY-CONSTRAINED MULTILAYER NONNEGATIVE MATRIX FACTORIZATION
Hyperspectral Imagery Nonnegative Matrix Factorization Multilayer Nonnegative Matrix Factorization Sparsity Constraint Endmember Extraction
2018/5/11
Due to the limited spatial resolution of remote hyperspectral sensors, pixels are usually highly mixed in the hyperspectral images. Endmember extraction refers to the process identifying the pure endm...
Factorization in non-leptonic decays of heavy mesons
Model calculation the heavy meson decays pseudoscalar transformation
2014/12/22
We propose a QCD-based model for calculation of the non-perturbative corrections to the factorization approximation in the decays of heavy mesons. In the framework of the model, factorization in pseud...
Factorization in graviton scattering and the "natural" value of the g factor
Graviton scattering amplitude gyromagnetic ratio independent of the rotation
2014/12/20
The factorization property of graviton scattering amplitudes is reviewed and show to be valid only if the "natural" value of the gyromagnetic ratio $g_S=2$ is employed -- independent of spin.

Multijet cross sections at the LHC and Tevatron are sensitive to several distinct kinematic energy scales.
Real and virtual corrections in NNLO QCD require multi-dimensional integrals with overlapping singularities. We first review ideas and methods which have been proposed for performing such computations...

Two nucleon correlations Three- and four-body systems Nuclear spectral function
2011/1/6
Recent BNL and Jlab data provided new evidence on two nucleon corre-lations (2NC) in nuclei. The data confirm the validity of the convolution model, de-scribing the spectral function (SF) of a correla...

Recently, Del no and Viti have examined the factorization of the three-point density correlation function P3 at the percolation point in terms of the two-point density correlation functions P2.
Factorization breaking in high-transverse-momentum charged-hadron production at the Tevatron?

2010/3/16
We compare the transverse momentum (p_T) distribution of inclusive light-charged-particle production measured by the CDF Collaboration at the Fermilab Tevatron with the theoretical prediction evaluate...
Exact solutions of a particle in a box with a delta function potential: The factorization method

2010/3/10
We find the exact eigenvalues and eigenfunctions for the problem of a particle in a box with a delta function potential $V(x)=\lambda\delta(x-x_{0})$ using the factorization method. We show that the p...
