An exact Markovian decoherence dynamics of two interacting harmonic oscillators coupled to a bosonic heat bath
We present an exact analytical solution of the Hu-Paz-Zhang master equation in a precise Markovian limit for a system of two harmonically coupled harmonic oscillators interacting with a common thermal bath of harmonic oscillators. The thermal bath is initially considered to be at arbitrary temperatures and characterized by an Ohmic Lorentz-Drude spectral density. In the examined system, couplings between the two harmonic oscillators and the environment ensure a complete decoupling of the center…

Always-convex harmonic shears
We determine completely the analytic functions $φ$ in the unit disk $\mathbb D$ such that for all (normalized) orientation-preserving harmonic mappings $f=h+\overline g$ which satisfy $h+ g=φ$, the condition that $f$ maps $\mathbb D$ onto a convex domain holds. As a consequence, we obtain the following more general result: for a given complex number $η$, with $|η|=1$, we characterize those holomorphic mappings $φ$ in $\mathbb D$ such that every harmonic function $f=h+\overline g$…

On a Mixed Arithmetic-Mean, Geometric-Mean, Harmonic-Mean Inequality
A mixed arithmetic-mean, geometric-mean inequality was conjectured by F. Holland and proved by K. Kedlaya. In this note, we prove a mixed arithmetic-mean, harmonic-mean inequality and a mixed geometric-mean, harmonic-mean, and a more extended inequality: a mixed arithmetic-mean, geometric-mean, harmonic-mean inequality.

Enhanced Control of High Harmonic Generation in Mixed Argon-Helium Gaseous Media
High harmonic generation (HHG) in gaseous media provides a robust method for producing coherent extreme-ultraviolet (EUV) radiation and attosecond pulses. However, the spectral and temporal properties of these pulses -- such as bandwidth and chirp -- are fundamentally limited by the underlying generation mechanisms. Typically, tailoring the EUV emission involves modifying the properties of the intense infrared femtosecond driving pulse, and/or the macroscopic laser-matter configuration. Here, w…
