摘要

Inflation driven by a single dark spinor field is discussed. We define the notion of a dark spinor field and derive the cosmological field equations for such a matter source. The conditions for inflation are determined and an exactly solvable model is presented. We find the power spectrum of the quantum fluctuation of this field and compare the results with scalar field inflation.

Unifying dark matter, dark energy and inflation with a fuzzy dark fluid

A. Arbey, J-F Coupechoux

Summary: This paper explores the possibility of a scalar field replacing dark matter, dark energy, and inflation by introducing a non-minimal coupling to gravity, a Mexican hat potential, and spontaneous symmetry breaking. The scalar field behaves like a dark fluid after inflation, mimicking the properties of both dark energy and dark matter.

Inflation and dark matter in the Z5 model

XinXin Qi, Hao Sun

Summary: We discuss the possibility of unifying dark matter physics and inflation in the Z(5) model of two-component dark matter. Inflation driven by the two-component dark matter fields can be divided into two cases, singlet dark matter inflation and mixed dark matter inflation, where both two-component play the role of inflaton in the latter case. For dark matter, we focus on the mixed dark matter inflation case. We show a viable parameter space that satisfies the theoretical and dark matter relic density constraint in the case of successful inflation. It turns out that the dark matter density is dominated by the light component, which is consistent with the feature of the Z(5) model of two-component dark matter.

Connecting primordial gravitational waves and dark energy

Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder

Summary: This study explores the connection between early universe inflation and present-day dark energy through quintessential inflation without a cosmological constant. The researchers demonstrate a robust relationship between the dark energy equation of state parameter and the primordial tensor to scalar ratio for a wide range of initial conditions. The study suggests that upcoming cosmic microwave background and galaxy redshift surveys can test the consistency condition.

Gravitational waves from dark sectors, oscillating inflatons, and mass boosted dark matter

Amit Bhoonah, Joseph Bramante, Simran Nerval, Ningqiang Song

Summary: Studying gravitational wave signatures from first order phase transitions and oscillations after inflation reveals interesting connections between dark matter and scalar fields, with MHz-GHz gravitational wave sensitivity being crucial for discovering the heaviest dark sectors. The study also finds that scalar fields undergoing phase transitions and E-Model or T-Model potentials can lead to late-time dark matter mass boosts, potentially generating dark matter masses up to the Planck mass. Additionally, higher amplitude stochastic gravitational wave backgrounds correspond to the largest dark matter mass boosts in phase transitions and oscillating inflatons.

Spin-driven stationary turbulence in spinor Bose-Einstein condensates

Deokhwa Hong, Junghoon Lee, Jongmin Kim, Jong Heum Jung, Kyuhwan Lee, Seji Kang, Y. Shin

Summary: We have observed stationary turbulence in antiferromagnetic spin-1 Bose-Einstein condensates driven by a radio-frequency magnetic field. The injected energy from the magnetic driving causes the emergence of an irregular spin texture in the condensate. Under continuous driving, the condensate evolves into a nonequilibrium steady state with spin turbulence, while the low-energy scale of spin excitations minimally affects the sample's lifetime. When the driving strength is comparable to the system's spin interaction energy and quadratic Zeeman energy, the stationary turbulent state exhibits spin-isotropic features.

Kaniadakis holographic dark energy and cosmology

Niki Drepanou, Andreas Lymperis, Emmanuel N. Saridakis, Kuralay Yesmakhanova

Summary: We propose a holographic dark energy scenario based on Kaniadakis entropy, using the future event horizon as the cutoff. We derive the differential equation for the evolution of the effective dark energy density parameter and provide analytical expressions for the equation-of-state and deceleration parameters. Our results show that the universe undergoes a standard thermal history, with the transition to acceleration occurring at z approximately 0.6. The dark energy equation-of-state parameter exhibits a rich behavior, being quintessence-like, phantom-like, or experiencing the phantom-divide crossing in the past or future. In the far future, dark energy dominates completely, with the asymptotic value of its equation of state depending on the model parameters.

Dark matter and gravitational waves from a dark big bang

Katherine Freese, Martin Wolfgang Winkler

Summary: The hot big bang is believed to be the origin of all matter and radiation in the Universe. Primordial nucleosynthesis provides strong evidence for the existence of a hot plasma in the early Universe. This paper describes a scenario in which dark matter can be formed around or even after primordial nucleosynthesis in a second big bang, called the dark big bang. The dark big bang occurs through a phase transition in the dark sector.

Primordial black holes as dark matter and gravitational waves from bumpy axion inflation

Ogan Ozsoy, Zygmunt Lalak

Summary: The study investigates a mechanism within string theory inspired models of inflation for producing primordial black holes and a gravitational wave background, presenting an example of axion inflation that matches CMB observations and generates a population of light PBHs that can explain dark matter. The resulting GW signal inherits specific properties of its scalar sources, potentially allowing for distinguishing this mechanism from other inflationary scenarios and astrophysical backgrounds.

Implications of quantum gravity for dark matter in the brane-world scenario

Cao H. Nam

Summary: Based on the swampland program, this study suggests that if this program is true, the brane-world scenario with branon dark matter would be ruled out. The constraints of quantum gravity imply that the branons must be absorbed by the KK gauge bosons, which leads to a geometric unification of gravity and dark matter. The KK gauge boson dark matter provides a promising observation window to search for weakly interacting dark matter in the cosmic microwave background and primordial gravitational waves.

Aspects of the dark dimension in cosmology

Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Luest

Summary: It has been recently discovered that the swampland conjectures can offer a solution to the cosmic hierarchy problem, explaining the smallness of dark energy by introducing an internal (dark) dimension in the micron range. Additionally, the coupling of Standard Model fields to massive spin-2 Kaluza-Klein excitations in this dark dimension can lead to a dark matter candidate. The model poses challenges for experimental probing, but it can accommodate neutrino masses and has implications for cosmology.

Fluctuating dark energy and the luminosity distance

Casper J. G. Vedder, Enis Belgacem, Nora Elisa Chisari, Tomislav Prokopec

Summary: The mysterious origin of dark energy driving the accelerated expansion of the universe is explored in this study. The possibility of dark energy fluctuations resulting in spatial correlations is discussed. The effect of these fluctuations on measurements of type Ia supernovae, which are used to constrain the luminosity distance, is investigated. It is found that the luminosity distance is affected in several ways, including differences from the standard ACDM and the emergence of angular correlations in the luminosity distance.

Axionlike particle inflation and dark matter

Wei Cheng, Ligong Bian, Yu-Feng Zhou

Summary: In this paper, a generalized natural inflation model is proposed to study axionlike particle inflation and dark matter. With two additional parameters, the model can achieve small-field inflation and the axionlike particle inflaton can serve as a dark matter candidate in certain parameter spaces. This model considers cosmic microwave background and other cosmological observation limits.

Compatibility conditions of continua using Riemann-Cartan geometry

Christian G. Bohmer, Yongjo Lee

Summary: The study examines compatibility conditions for generalised continua within the framework of differential geometry, particularly Riemann-Cartan geometry. It is shown that Vallee's and Nye's tensor's compatibility conditions are equivalent to the vanishing of the three-dimensional Einstein tensor, highlighting the pivotal role it plays in continuum mechanics. Further compatibility conditions are discussed using a geometric approach and applied to microcontinuum theories.

Dynamical Systems Analysis of f(Q) Gravity

Christian Bohmer, Erik Jensko, Ruth Lazkoz

Summary: Modified gravity theories describe homogeneous and isotropic cosmological models through field equations. These equations can be transformed into autonomous differential equation systems due to their dependence on a well-chosen time variable. This allows for a reliable study of the equations using a dynamical systems approach. Through a model-independent set of variables, all f(Q) modified gravity models can be analyzed. The drawback is a more complicated constraint equation, but it reduces the dimensions of the dynamical system compared to other methods. We focus on the power-exponential model and generalize its fluid content.

Modified gravity: A unified approach

Christian G. Boehmer, Erik Jensko

Summary: By proposing a new setup based on the original Einstein action, we can formulate modified gravity theories with second or fourth order field equations. Our theory is equivalent to the f(Q) gravity models, as well as capable of reproducing f(R) and f(T) gravity. Different from these theories, our approach emphasizes the importance of boundary terms in establishing the equivalence between them.
