Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe

open access: yesAdvanced Functional Materials, EarlyView.
In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

open access: yesAdvanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Evolutionary Game Theory

open access: yes, 2023
Evolutionary game theory originated in population biology from the realisation that frequency-dependent fitness introduced a strategic element into evolution. Since its development, evolutionary game theory has been adopted by many social scientists, and

Evolutionary Theory of Cancer

Annals of the New York Academy of Sciences, 2009
As Theodosius Dobzhansky famously noted in 1973, “Nothing in biology makes sense except in the light of evolution,” and cancer is no exception to this rule. Our understanding of cancer initiation, progression, treatment, and resistance has advanced considerably by regarding cancer as the product of evolutionary processes.

Evolutionary Theory of History

History and Theory, 1999
Several attempts have been made recently to apply Darwinian evolutionary theory to the study of culture change and social history. The essential elements in such a theory are that variations occur in a population, and that a process of selective retention operates during their replication and transmission.

Evolutionary Game Theory

Physica D: Nonlinear Phenomena, 1980
Evolutionary game theory is a method of analysing the evolution of phenotypes when fitnesses are frequency-dependent. The assumption made about inheritance is the simplest possible one, that individuals produce offspring identical to themselves — i.e. parthenogenetic inheritance.

A test of evolutionary theories of senescence

Nature, 1980
Senescence is the post-maturation decline in survivorship and fecundity that accompanies advancing age. Two main evolutionary theories have been proposed to account for senescence. (1) The mutation-accumulation theory. Deleterious mutations exerting their effects only late in life would tend to accumulate, because of their minimal effects ...

An evolutionary theory of cuisine

Human Nature, 1990
The evolution of human diet is the product of both biological and cultural adaptations to various plants and animals in the environment. This paper develops a new theory for the evolution of cuisine practices which attempts to account for how food processing provided a critical link in enhancing the nutrient balance of major domesticated plants.
