Quantum simulation of an extended Dicke model with a magnetic solid

Communications Materials
The Dicke model describes the cooperative interaction of an ensemble of two-level atoms with a single-mode photonic field and exhibits a quantum phase transition as a function of light–matter coupling strength. Extending this model by incorporating short-

Infochemicals in tritrophic interactions : origin and function in a system consisting of predatory mites, phytophagous mites and their host plants [PDF]

, 1988
What are infochemicals?Chemical compounds play an important role in interactions between organisms. Some of these chemicals are to the benefit (e.g. nutrients) or detriment (e.g. toxins) of an organism.

Essential work of fracture and absorbed energy by Charpy impact test of TRIP780 1.5 mm thick sheet steel Kerbschlagarbeit und absorbierte Energie bei der Charpy‐Schlagprüfung an 1,5 mm dickem Restaustenitstahlblech (HCT 780)

Materialwissenschaft und Werkstofftechnik, EarlyView.
The study demonstrated that absorbed energy (Charpy impact test) and fracture toughness (EWF test) are essential for evaluating the mechanical performance of thin sheet metallic materials. Transformation‐induced plasticity (TRIP) steels have been extensively studied concerning their mechanical performance under monotonic loading and conventional ...

Spin-only dynamics of the multi-species nonreciprocal Dicke model

SciPost Physics
The Hepp-Lieb-Dicke model is ubiquitous in cavity quantum electrodynamics, describing spin-cavity coupling which does not conserve excitation number. Coupling the closed spin-cavity system to an environment realizes the open Dicke model, and by tuning ...

Exact solutions and accelerating universe in modified Brans–Dicke theories

European Physical Journal C: Particles and Fields, 2019
Exact solutions are studied in the context of modified Brans–Dicke theory. The non-linearity of the modified Brans–Dicke field equations is treated with the Euler–Duarte–Moreira method of integrability of anharmonic oscillator equation.

Nonlinear semiclassical dynamics of the unbalanced, open Dicke model

Physical Review Research, 2020
In recent years there have been significant advances in the study of many-body interactions between atoms and light confined to optical cavities. One model that has received widespread attention of late is the Dicke model, which under certain conditions ...

Interview with Marcel Dicke: the Droste effect in science

, 2015
Marcel Dicke grew up at the outskirts of Rotterdam, The Netherlands. He enjoyed strolling through the meadows and jumping over ditches to observe animals and plants. He was interested in life in general and his interest in biology, and especially ecology,

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

DYNAMICS OF ANISOTROPIC SHARMA-MITTAL HOLOGRAPHIC DARK ENERGY MODEL IN BRANS-DICKE THEORY [PDF]

Proceedings on Engineering Sciences
The Brans-Dicke scalar-tensor theory of gravity (Phys. Rev. 124, 925: 1961) is applied in this work to study the Sharma-Mittal holographic dark energy on a background of anisotropic and spatially homogenous Bianchi type-II spacetime.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.
