The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Advanced pseudocapacitive performances of a Ti3C2Tx‐ZnOHF/ZnO nanocomposite for energy storage applications

open access: yesChemSusChem, Accepted Article.
The growing demand for efficient and high‐performance energy storage systems is driving the exploration of novel materials and composites. Traditional electrode materials often face limitations in terms of energy and power densities. This paper demonstrates novel spray‐coated cathode electrode system composed of Ti3C2Tx MXene and zinc hydroxy fluoride ...

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

The sensitivity of the Higgs boson branching ratios to the W boson width

open access: yesPhysics Letters B, 2016
The Higgs boson branching ratio into vector bosons is sensitive to the decay widths of those vector bosons because they are produced with at least one boson significantly off-shell.

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

The Lived Experience of No Longer Being Able to Play a Musical Instrument Due to Physical Impairments: A Heuristic Study

open access: yesThe Journal of Humanistic Counseling, EarlyView.
ABSTRACT For musicians, injury or illness can mean not only the loss of performance opportunities but also the end of a lifetime's calling. What is it like to face such a profound change? This study explores the lived experience of musicians who could no longer play their instruments due to a physical impairment.

Photonic implementation of boson sampling: a review

open access: yesAdvanced Photonics, 2019
. Boson sampling is a computational problem that has recently been proposed as a candidate to obtain an unequivocal quantum computational advantage. The problem consists in sampling from the output distribution of indistinguishable bosons in a linear ...

Diagrammatic Schemes for Nonlinear Optical Interactions

open access: yesJournal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (

Search for a heavy Higgs boson decaying to a pair of W bosons in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2020
A search for a heavy Higgs boson in the mass range from 0.2 to 3.0 TeV, decaying to a pair of W bosons, is presented. The analysis is based on proton-proton collisions at $$ \sqrt{s} $$ s = 13 TeV recorded by the CMS experiment at the LHC in 2016 ...
