Abstract Research aimed at investigating the ideal plant arrangement system of common beans under intercropping with castor hybrids is necessary, as intercropping is a common practice in Brazil, and this practice affects the morphophysiological behav

The role of controlled disorder in the strong correlated narrow gap semiconductor candidate FeGa$_3$ has been investigated. Polycrystalline samples were synthesized by the combination of arc-melting furnace and successive annealing processes. Deviati

Extensively reported experimental observations indicate that on varying pressure ($p$) within the $\textit{T-p}$ phase diagram of most quantum critical heavy fermion (HF) superconductors, one identifies a cascade of distinct electronic states which m

We develop a rigorous, field-theoretical approach to the study of spontaneous emission in inertial and dissipative nematic liquid crystals, disclosing an alternative application of the massive Stueckelberg gauge theory to describe critical phenomena

We formulate the problem of unconventional $d-$wave superconductivity, with phase fluctuations, pseudogap phenomenon, and local Cooper pairs, in terms of a synchronization problem in random, quantum dissipative, elasto-nuclear oscillator networks. Th

Identifying universal scaling relations between two or more variables in a complex system plays a pivotal role in understanding various phenomena in different branches of science. Examples include the allometric scaling among food webs in biology, th

We study the spontaneous emission of agglomerates of two-level quantum emitters embedded in a correlated transparent metal. The characteristic emission energy corresponds to the splitting between ground and excited states of a neutral, nonmagnetic mo

We investigate nonradiative emission and absorption rates of two-level quantum emitters embedded in a metal at low temperatures. We obtain the expressions for both nonradiative transition rates and identify a unique, experimentally accessible way to

Abstract Fe3O4 nanoparticles were synthesized and functionalized with (3-aminopropyl) trimethoxysilane (APTMS) and chitosan, forming Fe3O4-NH2 and Fe3O4-NH2-chitosan nanoparticles. The Fe3O4 nanoparticles were synthesized by a co-precipitation method
