Broken symmetry solutions in one-dimensional lattice models via many-body perturbation theory

In this paper, we study self-consistent solutions in one-dimensional lattice models obtained via many-body perturbation theory. The Dyson equation is solved in a fully self-consistent manner via the algorithmic-inversion method based on the sum-over-poles representation (AIM-SOP) of dynamical operators. In particular, we focus on the GW approximation, analyzing the spectral properties and the emergence of possible magnetic- or charge-density-wave broken symmetry solutions. We start by validat...

Impact of glucose on a Gel-A-Based polyphenol biosensor: A QCM-D study

Polyphenols play a key role in the agrifood sector, particularly in winemaking and olive oil production, where they contribute to product quality assessment. In this study, the potential interference of glucose on our previously developed Gelatin type A-based polyphenol biosensor was evaluated using Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D). Since glucose is naturally present in grapes, olives, and their derivatives, its effect on the biosensor performance must be assess...

Distant Transport of Antimicrobial Protection by Implantable Polymeric Meshes

Implantable polymeric meshes are used to mechanically reinforce tissues and stabilize the surgical pocket of artificial implants, including cardiac implantable electronic devices and implantable neuromodulators. Their function depends on the mesh architecture formed by interlaced microfilaments and yarns. Antimicrobial protection can be added through uniform antibiotic-eluting coatings; however, these polymeric layers increase mesh rigidity and reduce porosity and compliance, thereby compromi...

Lifshitz transitions and isospin polarization in twist-decoupled monolayer-bilayer graphene

Bernal-stacked bilayer graphene (BLG) hosts correlated electronic phases tied to low-energy Lifshitz transitions at saddle points in its valence band. To access this regime, ultralow charge disorder and control over a vertical electric field are simultaneously required. Here, we employ a twist-decoupled monolayer (MLG) to bias a proximal BLG in the absence of an external displacement field (𝐷). We thereby reveal threefold degenerate quantum Hall states at 𝐷=0, with multiple transitions driv...

Integrated Imaging and Spectroscopic Analysis of Residual Polychromy on the Roman Sculptures of the National Archaeological Museum of Formia (LT), Italy

The study of ancient sculptural polychromy increasingly relies on non-invasive analytical approaches capable of identifying pigments and reconstructing original decorative schemes while preserving the integrity of archaeological objects. This paper presents the investigation of the polychromy, extraordinarily preserved, on two Roman marble statues discovered in the forum of Formia (southern Latium) and currently housed in the National Archaeological Museum of Formia: a togate statue (inv. 147...
