Impurities in a one-dimensional Bose gas: the flow equation approach

open access: yesSciPost Physics, 2021
A few years ago, flow equations were introduced as a technique for calculating the ground-state energies of cold Bose gases with and without impurities. In this paper, we extend this approach to compute observables other than the energy.

Electronic Correlation Effects in the Response of Graphene and MoS2 Monolayers to the Impact of Highly‐Charged Ions

open access: yesphysica status solidi (b), EarlyView.
The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.

High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Mechanical stability of resonant Bose-Fermi mixtures

open access: yesSciPost Physics
We investigate the mechanical stability of Bose-Fermi mixtures at zero temperature in the presence of a tunable Feshbach resonance, which induces a competition between boson condensation and boson-fermion pairing when the boson density is smaller than ...

Inclusive production cross sections at N3LO

open access: yesJournal of High Energy Physics, 2022
We present for the first time the inclusive cross section for associated Higgs boson production with a massive gauge boson at next-to-next-to-next-to-leading order in QCD.

Measurement of the associated production of a Higgs boson decaying into b-quarks with a vector boson at high transverse momentum in pp collisions at s=13 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2021
The associated production of a Higgs boson with a W or Z boson decaying into leptons and where the Higgs boson decays to a bb¯ pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data,

The Primacy of Processes and the Causes of the Russo‐Ukrainian War: A Rejoinder to ‘Patrimonial Imperialism’

open access: yesJournal for the Theory of Social Behaviour, Volume 56, Issue 1, March 2026.
ABSTRACT Pierzynski and Joseph explain the Russo‐Ukrainian war through systemic and individual‐level accounts but argue these are incomplete without addressing Russia's internal structure, which they term ‘patrimonial imperialism’. While their taxonomy mirrors the traditional IR ‘levels of analysis’, I suggest it obscures relational and historical ...

Bosonization of Fermionic Fields and Fermionization of Bosonic Fields [PDF]

open access: yesAdvances in Applied Clifford Algebras, 2017
In this paper using the Clifford and spin-Clifford bundles formalism we show how Weyl and Dirac equations formulated in the spin-Clifford bundle may be written in an equivalent form as generalized Maxwell like form formulated in the Clifford bundle. Moreover, we show how Maxwell equation formulated in the Clifford bundle formalism can be written as an ...

The issue of concession and a forgotten book

open access: yesRevista Mundos do Trabalho, 2022
The article aims to recover the reading of Some truths about our labor laws, by Aguinaldo Costa, an engineer from Pernambuco based in São Paulo and a writer inserted in editorial movements led by Caio Prado Júnior in the 1940s.

Coordinate‐ and Spacetime‐Independent Quantum Physics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept
