Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Linking and iteration signs in proving by mathematical induction [PDF]

, 2021
We focus on the role of signs in the process of constructing proofs by mathematical induction of high-achieving post-graduate students. Using a multimodal semiotic perspective, speech, written inscription (symbols, drawings, etc.), and gestures are analysed, and two particular categories of signs are identified and observed: linking signs and iteration

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Four Notes Towards Propaganda and the Post-Digital Symptom

A Peer-Reviewed Journal About, 2014
What is it about propaganda that Alan Turing deemed sufficient in describing a statement about puzzles, problems and solutions? Despite not being an overtly political writer, Turing’s relevancy is undoubtedly important for the politics of digital ...

Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...
