Warm Quasi-Single Field Inflation
, 2018 We study quasi-single field inflation with a warm inflation background. The thermal effects at small scales can sufficiently enhance the magnitude of the primordial standard clock signal.

A Quantum Field Theory Warm Inflation Model [PDF]
, 1999 A quantum field theory warm inflation model is presented that solves the cosmological horizon/flatness problems. An interpretation of the model is given from supersymmetry and superstring theory.Comment: 5 pages, 0 figure, Latex, presented COSMOS ...

Warm DBI inflation with constant sound speed
European Physical Journal C: Particles and Fields, 2019 We study inflation with the Dirac–Born–Infeld (DBI) noncanonical scalar field in both the cold and warm scenarios. We consider the Anti-de Sitter warp factor $$f(\phi )=f_{0}/\phi ^{4}$$ f(ϕ)=f0/ϕ4 for the DBI inflation and check viability of the quartic

Warm inflation with non-comoving scalar field and radiation fluid
European Physical Journal C: Particles and Fields, 2021 We consider a warm inflationary scenario in which the two major fluid components of the early Universe, the scalar field and the radiation fluid, evolve with distinct four-velocities.

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems
Advanced Science, EarlyView.Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Determining the regimes of cold and warm inflation in the susy hybrid model [PDF]
, 2004 The SUSY hybrid inflation model is found to dissipate radiation during the inflationary period. Analysis is made of parameter regimes in which these dissipative effects are significant.

Non-minimal coupled warm inflation with quantum-corrected self-interacting inflaton potential
European Physical Journal C: Particles and Fields, 2022 In this work, we investigate the non-minimally coupled scenario in the context of warm inflation with quantum-corrected self-interacting potential. We transform the potential in the Jordan frame to the Einstein frame and consider a dissipation parameter ...

Advanced Science, EarlyView.Using field‐based holo‐omics, we demonstrate that developmental shifts in sorghum leaf metabolomes drive a noncanonical fungal succession from stress tolerators (S) through ruderals (R) to competitors (C). Antifungal metabolites in young leaves select for S strategists with expanded genomes, transient maltose pulses during flowering favor fast‐growing ...

Noncanonical warm inflation with nonminimal derivative coupling [PDF]
Journal of Cosmology and Astroparticle PhysicsThis study extended noncanonical warm inflation to the nonminimal derivative coupling scenario. The fundamental equations, including the evolution equations and the slow roll equations of this new framework, were derived. The enlarged damping term, which

Advanced Science, EarlyView.Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...
