Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime
Contributions to Plasma Physics, EarlyView.ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

On the wave operators for the critical nonlinear Schrodinger equation [PDF]
arXiv, 2007 We prove that for the mass critical nonlinear Schrodinger equations, the wave operators and their inverse are related explicitly in terms of the Fourier transform. We discuss some consequences of this property. In the one-dimensional case, we show a precise similarity between the mass critical nonlinear Schrodinger equation and a nonlinear Schrodinger ...

Joint Implied Willow Tree: An Approach for Joint S&P 500/VIX Calibration
Journal of Futures Markets, Volume 45, Issue 6, Page 547-568, June 2025.ABSTRACT Since the inception of Volatility Index (VIX) options trading, academic literature has persistently sought accurate methods for jointly calibrating the prices of the S&P 500 index (SPX) and VIX options. This study introduces a novel nonparametric approach, called the joint implied willow tree (JIWT) method, aimed at resolving this joint ...

Experimental Emulator of Pulse Dynamics in Fractional Nonlinear Schrödinger Equation
Laser &Photonics Reviews, Volume 19, Issue 8, April 17, 2025.The authors present an experimental emulator to investigate pulse dynamics within the framework of the fractional nonlinear Schrödinger equation. By tailoring fractional group‐velocity dispersion and Kerr nonlinearity in an optical cavity, distinctive spectral‐temporal phenomena, including fractional solitons and spectral valleys, are unveiled.
