Structural Properties of Yukawa One‐Component Plasmas Revisited

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACTYukawa one‐component plasmas are fully described in terms of the Coulomb coupling parameter Γ$$ \Gamma $$ and the screening parameter κ$$ \kappa $$. One of their remarkable properties is the existence of lines of constant effective coupling, Γeff(Γ,κ)$$ {\Gamma}_{\mathrm{eff}}\left(\Gamma, \kappa \right) $$, along which their short‐range ...

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.

A phase-space approach for propagating field–field correlation functions

open access: yesNew Journal of Physics, 2015
We show that radiation from complex and inherently random but correlated wave sources can be modelled efficiently by using an approach based on the Wigner distribution function.

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Wigner distribution functions for complex dynamical systems: The emergence of the Wigner-Boltzmann equation [PDF]

open access: yesPhysical Review E, 2013
The equation of motion for the reduced Wigner function of a system coupled to an external quantum system is presented for the specific case when the external quantum system can be modeled as a set of harmonic oscillators. The result is derived from the Wigner function formulation of the Feynman-Vernon influence functional theory.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Robust Time-Frequency Distributions with Complex-Lag Argument

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
The robust time-frequency distributions with complex-lag argument are proposed. They can provide an accurate estimation of fast varying instantaneous frequency in the presence of noise with heavy-tailed probability density function.

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Wigner function and photon number distribution of a superradiant state in semiconductor heterostructures

open access: yesNew Journal of Physics, 2020
Advanced quantum technologies require sources of non-Gaussian and non-classical light. For the understanding of properties of quantum light it is necessary to reconstruct its quantum state.

Effects of Transition Metals (TM = Nb, Ta, and Zr) on Thermodynamic and Electronic Properties of Advanced (Th1−xTMx)C (x = 0.1 and 0.2) Fuels: A First‐Principles Study

open access: yesMaterials Genome Engineering Advances, EarlyView.
First‐principles study reveals Zr‐doped ThC maintains superior thermal conductivity and rigidity; Ta‐doping induces structural softening, whereas Nb enhances covalent bonding. These atomic‐scale insights guide the design of advanced thorium‐based nuclear fuels with tailored thermomechanical properties.
