\section{Introduction} A fundamental principle of the quantum theory is that, while the underlying wave function may be complex, eigenvalues of energy and other physically relevant quantities must be real, which is provided by the condition that the respective Hamiltonian is self-conjugate (Hermitian) \cite{qm}. On th...

\section*{Introduction} Bound quiver algebras of finite connected quivers strongly influence research on representation theory of Artin algebras.

\section{Introduction} The spectrum of triply-ionized tin (Sn$^{3+}$) was first observed by Rao nearly a century ago \cite{Rao1926}. Accurate estimations of transition lines of Sn IV have astrophysical interest since their detection in the stellar medium \cite{O'Toole2004, Chayer2005}. Using the Hubble's Space Telescop...

\section{Intruduction} Phase transitions in two-dimensional systems with a continuous symmetry have long attracted much attentions since the theoretical prediction by Berezinskii, Kosterlitz and Thouless (BKT), providing a topological ordering through the binding of vortex-antivortex pairs \cite{Berezinskii,Kosterlitz...
