The Smearing of Quasi‐Particles: Signatures in the Entanglement Entropy of Excited Many‐Particle Systems

open access: yesAdvanced Quantum Technologies, EarlyView.
Entanglement reveals hidden structure in quantum matter. We explore how quasi‐particles shape the crossover from area‐law to volume‐law entanglement, using models from spinless fermions to SYK. Our results show a striking linear growth of entanglement with energy, explained as a hallmark of quasi‐particles, offering new insight into the entanglement ...

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

open access: yesSmall, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

open access: yesSmall, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Self-similar decay to the marginally stable ground state in a model for film flow over inclined wavy bottoms

open access: yesElectronic Journal of Differential Equations, 2012
The integral boundary layer system (IBL) with spatially periodic coefficients arises as a long wave approximation for the flow of a viscous incompressible fluid down a wavy inclined plane. The Nusselt-like stationary solution of the IBL is linearly at

MnBr2${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super‐Moiré

open access: yesSmall, EarlyView.
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Discrimination of Tryptophan Enantiomers at Sub‐pm Level by Multiparametric Analysis of a Label‐Free Organic Immunosensor

open access: yesSmall Methods, EarlyView.
Multiparametric analysis is a crucial aspect for enhancing the final sensitivity of biosensors based on organic transistors. The traditional approaches to treat the experimental data are not always suitable to extract the correct response. In this work EGOT characteristics are processed to achieve enantiodiscrimination of free Tryptophan enantiomers ...
