Inflation in supersymmetric cosmic string theories [PDF]
Physics Letters B, 1999 We examine a non-Abelian SUSY $SU(2) \times U(1)$ gauge theory and a SUSY U(1) theory originally used to investigate the microphysics of cosmic strings in supersymmetric theories. We show that both theories automatically include hybrid inflation. In the latter theory we use a $D$ term to break the symmetry.

Quintessential inflation for exponential type potentials: scaling and tracker behavior
European Physical Journal C: Particles and Fields, 2021 We will show that for exponential type potentials of the form $$V(\varphi )\sim e^{-\gamma \varphi ^n/M_{pl}^n}$$ V ( φ ) ∼ e - γ φ n / M pl n , which are used to depict quintessential inflation, the solutions whose initial conditions take place during ...

Phenomenological Inflationary Model in Supersymmetric Quantum Cosmology
Universe, 2022 We consider the effective evolution of a phenomenological model from FLRW supersymmetric quantum cosmology with a scalar field. The scalar field acts as a clock and inflaton.

Quantum cosmic no-hair theorem and inflation [PDF]
Physical Review D, 2019 We consider implications of the quantum extension of the inflationary no hair theorem. We show that when the quantum state of inflation is picked to ensure the validity of the EFT of fluctuations, it takes only ${\cal O}(10)$ efolds of inflation to erase the effects of the initial distortions on the inflationary observables.

Signals of Bursts from the Very Early Universe
The Astrophysical JournalWe consider possible observable signals from explosive events in the very early Universe, dubbed “bursts.” These could be expected in connection with massive black hole or “baby Universe” formation.

Evading Lyth bound in models of quintessential inflation
Physics Letters B, 2014 Quintessential inflation refers to an attempt to unify inflation and late-time cosmic acceleration using a single scalar field. In this letter we consider two different classes of quintessential inflation, one of which is based upon a Lagrangian with non-

Cross‐Modal Denoising and Integration of Spatial Multi‐Omics Data with CANDIES
Advanced Science, EarlyView.In this paper, we introduce CANDIES, which leverages a conditional diffusion model and contrastive learning to effectively denoise and integrate spatial multi‐omics data. We conduct extensive evaluations on diverse synthetic and real datasets, CANDIES shows superior performance on various downstream tasks, including denoising, spatial domain ...
