Vibrational sum frequency generation (SFG) spectroscopy can selectively probe noncentrosymmetric arrangements of molecules or crystalline domains buried in amorphous bulk phases. This attribute makes ...
ABSTRACT: Variational methods are highly valuable computational tools for solving high-dimensional quantum systems. In this paper, we explore the effectiveness of three variational methods: density ...
We present an on-shell scheme to renormalize the Cabibbo-Kobayashi-Maskawa (CKM) matrix. It is based on a novel procedure to separate the external-leg mixing corrections into gauge-independent ...

Now we define a new class called `Diag`, this class receive a container that can be the parameter of `std::data`, e.g `std::vector`, `std::initializer_list`. This class is for specify a diagonal ...
This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of ...
In the world of mathematics, matrices play a crucial role in solving complex problems and performing various calculations with ease. Matrices are arrays of numbers, symbols, or expressions that are ...
