Hermitian beam
Witryna3 kwi 2024 · Abstract. This study is started from a photon-magnon model with a competition effect of the level attraction and repulsion, its Hermiticity is mainly decided by a phase-dependent and asymmetric coupling factor, namely ϕ = 0 for Hermitian and ϕ = π for non-Hermitian. Then an extensional study predicts the quantum critical … WitrynaThis happens because the geometric matrix is obtained using Hermitian polynomials which are approximate solutions. To circumvent this issue, the frame element’s tangent matrix is obtained using interpolation functions that match the homogeneous solution of the differential equation of the beam-column problem. ...

Because of the … WitrynaAbstract We investigate photon coalescence in a lossy non-Hermitian system and study a dynamic device modeled by a beam splitter with an extra intrinsic phase term added in the transformation matrix, with which the device is a lossy non-Hermitian linear system. The two-photon interference behavior is altered accordingly since this extra intrinsic …
Witryna2. To get the hermite shape functions it is necessary to solve for the constants in terms of the nodal quantities. Ie, boundary conditions for the beam element, they are v(X=0)=v1 v,x(X=0)=theta1 v(X=L)=v2 v,x(X=L)=theta2 ,where L is the length of the beam element.
Witryna16 sty 2024 · In non-Hermitian systems, it is known that one band of eigenstates can smoothly switch to another band without crossing any degeneracy points (or exceptional points as called in non-Hermitian systems) along a closed loop in the parameter space . Mathematically, this is a Möbius loop.
