Quantum Phase Transition in a Pseudo-hermitian Dicke model
Quantum Phase Transition Pseudo-hermitian Dicke model
2010/4/8
We show that a Dicke-type pseudo-hermitian Hamiltonian undergoes quantum phase transition by mapping it to the "Dressed Dicke Model" through a similarity transformation. We find the positive-definite ...
On the Spectrum of a Discrete Non-Hermitian Quantum System
difference operator non-Hermiticity spectrum eigenvalue eigenvector completely continuous operator
2010/4/13
In this paper, we develop spectral analysis of a discrete non-Hermitian quantum system that is a discrete counterpart of some continuous quantum systems on a complex contour. In particular, simple con...

The Inertia of Hermitian Tridiagonal Block Matrices
Tridiagonal Block Matrices Hermitian Matrices Inertia Patterned Matrix
2008/6/26
Let H be a partitioned tridiagonal Hermitian matrix. We characterized the possible inertias of H by a system of linear inequalities involving the orders of the blocks, the inertia of the diagonal bloc...
Derivation of the Laplace-Beltrami operator for the zonal polynomials of positive definite Hermitian matrix argument
Laplace-Beltrami operator linear structures
2010/9/14
Some aspects of the complex linear structure theory, extending the real case due to Magnus (1988), are defined and studied. This theory provides complete proofs of conjectures given in literature arou...

Non-Hermitian positive definite matrix Matrix splitting Preconditioning Krylov subspace method Convergence
2007/12/12
A shift splitting concept is introduced and, correspondingly,
a shift-splitting iteration scheme and a shift-splitting
preconditioner are presented,
for solving the large sparse system of linear eq...

2007/12/11
Let $D$ be any division ring with an involution, ${\mathscr H}_n(D)$ be the space of all $n\times n$ hermitian matrices over $D$. Two hermitian matrices $A$ and $B$ are said to be adjacent if ${\rm ra...

Explicit Realization of Pseudo-Hermitian and Quasi-Hermitian Quantum Mechanics for Two-Level Systems
Pseudo-Hermitian quasi-Hermitian metric operator observable two-level system
2010/4/9
We give an explicit characterization of the most general quasi-Hermitian operator H, the associated metric operators h+, and h+-pseudo-Hermitian operators acting in C2. The latter represent the physic...
Extreme Points of Certain Subsets of Hermitian Elements in Banach Algebras
Extreme points hermitian elements
2010/2/26
We consider the real Banach spaces H(A) of all hermitian elements of a complex Banach algebra A. We prove that if an even power of a \in N(A) is hermitian, then a is an extreme point of the unit ball ...
