Non-Hermitian Quantum Mechanics with Minimal Length Uncertainty
Symmetry, Integrability and Geometry: Methods and Applications, 2009 We study non-Hermitian quantum mechanics in the presence of a minimal length. In particular we obtain exact solutions of a non-Hermitian displaced harmonic oscillator and the Swanson model with minimal length uncertainty.

Moyal products -- a new perspective on quasi-hermitian quantum mechanics
, 2006 The rationale for introducing non-hermitian Hamiltonians and other observables is reviewed and open issues identified. We present a new approach based on Moyal products to compute the metric for quasi-hermitian systems.

On the Method of Harmonic Balance for Lumped‐Element Transformer Models
International Journal of Circuit Theory and Applications, EarlyView.The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Non-Hermitian spin chains with inhomogeneous coupling [PDF]
, 2010 An open U_q(sl_2)-invariant spin chain of spin S and length N with inhomogeneous coupling is investigated as an example of a non-Hermitian (quasi-Hermitian) model.

Scale‐Invariant Waveguiding in Flatland
Exploration, EarlyView.The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

On the evolution of a Hermitian metric by its Chern-Ricci form
, 2014 We consider the evolution of a Hermitian metric on a compact complex manifold by its Chern-Ricci form. This is an evolution equation first studied by M. Gill, and coincides with the Kahler-Ricci flow if the initial metric is Kahler.
