Cartographic Monsters and the Rise of Empiricism

XVII-XVIII, 2021
This paper studies the impact of empiricism on seventeenth-century cartographic monsters through the analysis of three maps: Jodocus Hondius’s 1598 map of the land described by Walter Ralegh in The discouerie of the large, rich, and bevvtiful empire of ...

Colossal Photovoltaic Current in Ferroelectric Oxide by Constructing Defect Band

Advanced Science, EarlyView.
Colossal photovoltaic current density of 34.36 mA/cm2 under 375 nm illumination has been achieved in the Pb‐deficient PbTiO3 film. The ultraviolet photoresponsivity surpasses that of all reported ferroelectric materials. This enhancement is attributed to the junction effect between the Pb‐deficient and non‐defective layers.

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

Advanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

The (Mostly) Unseen World of Cryptids: Legendary Monsters in North America

Humanities, 2023
North America is steeped in legends of cryptids, (mostly) unseen creatures woven into the fabric of its folklore. From legends told by early explorers to contemporary legends told today, these enigmatic beings shape societal perceptions and reflect ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Magnetotransport Signatures of Spin–Orbit Coupling in High‐Temperature Cuprate Superconductors

Advanced Science, EarlyView.
Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,

Computing in the Monster

Journal of Symbolic Computation, 2001
The author speculates on various possible methods of computing in the Monster sporadic simple group. The huge size of this group makes this a hard problem, but it seems clear that any efficient system must make use of fast computation in one or more (large) subgroups. Explicit descriptions of several such subgroups are given, together with some results

Selective Catalytic Production of Urea: Unravelling the Pairwise Competition on p‐d Alloy Catalysts

Advanced Science, EarlyView.
Unraveling the complicated competition in urea electrosynthesis, this work investigates asymmetric p‐d alloys. We establish two stage‐specific descriptors, Anchoring Affinity and Coupling Propensity, to elegantly quantify thermodynamic bottlenecks.

Terahertz‐Nanoscale Visualization of the Microscopic Spin‐Charge Architecture of Colossal Magnetoresistive Switching

Advanced Science, EarlyView.
This study employs cryogenic magneto‐terahertz nanoscopy to reveal the real‐space electrodynamics of the colossal magnetoresistance transition. By capturing the terahertz electrodynamic evolution of field‐driven spin switching, the work unveils the dissipative dynamics of emergent metallic states, providing a high‐frequency view of coupled spin‐charge ...

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

Advanced Electronic Materials, EarlyView.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\
