Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

Contributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Static overscreening and nonlinear response in the Hubbard Model

, 2001
We investigate the static charge response for the Hubbard model. Using the Slave-Boson method in the saddle-point approximation we calculate the charge susceptibility.

The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Superior Intracellular Detection of Cytokines, Transcription Factors, and Phosphoproteins by CyTOF Compared With Fluorescent Cytometry

Cytometry Part A, EarlyView.
ABSTRACT Unraveling biological complexity, such as immune subset distribution in infectious disease(s), autoimmunity, or tumor heterogeneity, requires technologies capable of single‐cell proteomic analysis such as flow cytometry. Surface phenotyping alone is often insufficient, as interrogating functional capacity is required to determine cellular ...

Inhomogeneous fluid of penetrable-spheres: application of the random phase approximation

, 2017
The focus of the present work is the application of the random phase approximation (RPA), derived for inhomogeneous fluids [Frydel and Ma, Phys. Rev. E 93, 062112 (2016)], to penetrable-spheres.

Neutral and Charged Anyon Fluids

, 1993
(Review) Properties of neutral and charged anyon fluids are examined, with the main focus on the question whether or not a charged anyon fluid exhibits a superconductivity at zero and finite temperature.

Placenta‐derived extracellular vesicles: Signal messengers shuttling across the maternal‐fetal barrier

Interdisciplinary Medicine, EarlyView.
In normal pregnancy, PEVs help maintain maternal–fetal immune tolerance while enabling controlled immune activation, promote endothelial migration, and support trophoblast invasion and syncytialization, strengthening antimicrobial defense. In pregnancy‐related disorders, dysregulated PEV signaling may drive endothelial dysfunction and hypertension, BBB

Renal screening sonography—A comparative study in a Portuguese basic emergency service

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 8-16, March 2025.
Renal sonography screening aids in clinical decision‐making for patients with suspected renal colic. This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with that of radiologists at Referral Hospital (RH) in Portugal. Renal sonography screening was able to detect
