Persistent Currents in Small, Imperfect Hubbard Rings
, 2003 We have done a study with small, imperfect Hubbard rings with exact diagonalization. The results for few-electron rings show, that the imperfection, whether localized or not, nearly always decrease, but can also \emph{increase} the persistent current ...

, 2022 This open access book synthesizes the swiftly growing critical scholarship on mistakes, glitches, and other aesthetics and logics of imperfection into the first transdisciplinary, transnational framework of imperfection studies. In recent years, the trend to present the notion of imperfection as a plus rather than a problem has resonated ...

Advanced Functional Materials, EarlyView.It is shown that interfaces between organic and inorganic layers govern long‐range stacking disorder and in‐plane anisotropy in 2D metal‐halide perovskites. By comparing single‐cation AB‐AB and ordered mixed‐cation ABCD‐ABCD stackings, SCXRD reveals enhanced mosaicity, while optics confirm high birefringence.

A note on the proof of magnetic flux quantization from ODLRO
, 1999 It is noticed that the excellent proof of the connection of magnetic flux quantization and off-diagonal long range order (ODLRO) presented recently by Nieh, Su and Zhao suffers from an imperfection, namely, the f-factors in the case of finite translation

Advanced Functional Materials, EarlyView.An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...

Chiral SURMOFs for Vibrational Circular Dichroism: Multiscale Modeling and Experimental Insights
Advanced Functional Materials, EarlyView.The use of solid‐state vibrational circular dichroism (VCD) for MOFs is still somewhat unexplored, and in this work, it is shown that chiral surface‐anchored MOFs (SURMOFs) grown on CaF2 provide an excellent platform for VCD. Experimental results are validated through multiscale modeling, showing strong agreement across multiple spectroscopic ...

Most adverse geometrical imperfections of steel spherical shells
Budownictwo i Architektura, 2014 Steel, spherical shells subjected to an external pressure are exposed to the loss of stability and such a phenomenon determines the global resistance of such shells.
