This paper assumes the BBT is correct.
Assumes Primordial Black Holes.
Without evidence, this paper falls short.
Regardless, read for yourself.

Here, we examine their formation in a bounce cosmology when the post-crunch universe inherits a highly inhomogeneous distribution of imprint entropy from the Quantum Memory Matrix (QMM). Within QMM, every Planck-scale cell stores quantum information about infalling matter; the surviving entropy field S(x) contributes an effective dust component T^QMM_{\mu\nu} = lambda * [ (nabla_mu S)(nabla_nu S) - (1/2) * g_{\mu\nu} * (nabla S)^2 + ... ] that deepens curvature wherever S is large

Information Wells and the Emergence of Primordial Black Holes in a Cyclic Quantum Universe​

Florian Neukart, Eike Marx, Valerii Vinokur
Primordial black holes (PBHs) remain one of the most intriguing candidates for dark matter and a unique probe of physics at extreme curvatures. Here, we examine their formation in a bounce cosmology when the post-crunch universe inherits a highly inhomogeneous distribution of imprint entropy from the Quantum Memory Matrix (QMM). Within QMM, every Planck-scale cell stores quantum information about infalling matter; the surviving entropy field S(x) contributes an effective dust component T^QMM_{\mu\nu} = lambda * [ (nabla_mu S)(nabla_nu S) - (1/2) * g_{\mu\nu} * (nabla S)^2 + ... ] that deepens curvature wherever S is large. We show that (i) reasonable bounce temperatures and a QMM coupling lambda ~ O(1) naturally amplify these "information wells" until the density contrast exceeds the critical value delta_c ~ 0.3; (ii) the resulting PBH mass spectrum spans 10^{-16} to 10^3 solar masses, matching current microlensing and PTA windows; and (iii) the same mechanism links PBH abundance to earlier QMM explanations of dark matter and the cosmic matter-antimatter imbalance. Observable signatures include a mild blue tilt in small-scale power, characteristic mu-distortions, and an enhanced integrated Sachs-Wolfe signal - all of which will be tested by upcoming CMB, PTA, and lensing surveys.

Jet outbursts, non-thermal pressure and the AGN jet duty cycle​

Andrew Sullivan, Ross J. Turner, Stanislav S. Shabala, Chris Power, Sophie A. Young
We predict the non-thermal pressure (NTP) induced in the cores of galaxy clusters by kinetic jet feedback from an active galactic nucleus (AGN). We model a population of Fanaroff-Riley type I jets when sampling power-law distributions in jet power and age, which we evolve in time with a two-phase jet-lobe model. We couple the energy of each jet outburst to the surrounding gas inside spherical shells, allowing us to estimate the fraction of NTP to total pressure induced in the cluster. We predict the mean profile for this NTP fraction over the source population in a variety of cluster environments and for different AGN jet duty cycles. For typical gas and dark matter profiles, the mean NTP fraction peaks at ~4-6% when the AGN jets are active for 10-30% of the total AGN lifecycle. These predictions are in good agreement with observational constraints, suggesting that AGN feedback imparts only small non-thermal contributions to the cluster's core. Furthermore, we find a relationship between the peak in the mean NTP fraction and the AGN jet duty cycle in a given cluster environment. Applying this to Hitomi measurements of the NTP in the Perseus cluster, we infer an AGN jet duty cycle that is consistent with independent evidence of Perseus' AGN jet activity. We propose this as a novel approach for observationally inferring the past AGN activity of real clusters from their observed NTP fraction and environmental profiles.
 
I think within 10 years we will be at stage of understanding how matter can be recycled and rejuvenated.

Nonequilibrium orders in parametrically driven field theories​

Carl Philipp Zelle, Romain Daviet, Andrew J. Millis, Sebastian Diehl
Driving quantum materials with coherent light has proven a powerful platform to realize a plethora of interesting phases and transitions, ranging from ferroelectricity to superconductivity and limit cycles in pumped magnonics. In this paper we develop the field theoretical framework to describe nonequilibrium phases that emerge in systems pumped by rapid parametric drives. We consider paradigmatic O(N) models that describe the long-wavelength fluctuations of ordering fields in many condensed matter set ups. We show that rapid parametric driving of these models can induce an effective pump mechanism in the long wavelength regime through nonlinear scattering. This induces a nonequilibrium transition into a time-crystalline phase.

Jet outbursts, non-thermal pressure and the AGN jet duty cycle​

Andrew Sullivan, Ross J. Turner, Stanislav S. Shabala, Chris Power, Sophie A. Young

Harry, has this something in common with my ideas on expansion/contraction within an observable, universe, perhaps many such within a larger "observable universe?

For example, within a Flatland analogy, expansion/contraction of multiple (flatland) observable universes within a (D+1) observable universe. Whatever other factors might be afoot, entropy would not be a factor within 'cyclic' flatland o/u's, only being applicable within the (D+1) observable universe (viz within the total system).

I am not proposing this as a solution - just as a thought experiment.

How matter recycles allows us to work with the age of Stars and galaxies.

Although three states can coexist spatially under thermal equilibrium, the scaling exponents of the transitions to the wave modes are modified from the equilibrium values.

Dynamic modes of active Potts models with factorizable numbers of states​

Hiroshi Noguchi
We studied the long-term nonequilibrium dynamics of q-state Potts models with q = 4, 5, 6, and 8 using Monte Carlo simulations on a two-dimensional square lattice. When the contact energies between the nearest neighbors for the standard Potts models are used, cyclic changes in the q homogeneous phases and q-state coexisting wave mode appear at low and high flipping energies, respectively, for all values of q. However, for a factorizable q value, dynamic modes with skipping states emerge, depending on the contact energies. For q = 6, a spiral wave mode with three domain types (one state dominant or two states mixed) and cyclic changes in three homogeneous phases are found. Although three states can coexist spatially under thermal equilibrium, the scaling exponents of the transitions to the wave modes are modified from the equilibrium values.

A Homologous Recycling Model for Hot Galactic Coronae​

Alexei Kritsuk (St. Petersburg University)
An equilibrium model is presented for a hydrostatic isothermal hot gas distribution in a gravitational well of a giant elliptical galaxy immersed in a massive dark halo. The self-consistently determined gravitational potential of the system provides the optical surface brightness distribution of the galaxy, matching the de Vaucouleurs R^1/4-law, if the sound speed in the gas, stellar velocity dispersion, and velocity dispersion of dark matter are related so that optical and X-ray brightness profiles match each other.
The thermal equilibrium of the gas is described in the framework of a one-zone model, which incorporates radiative cooling, stellar mass loss, supernova heating, and mass sink due to local condensational instability. The sequence of saddle-node and saddle-connection bifurcations provides a first-order phase transition, which separates the stable hot phase in the cooling medium for a reasonably high efficiency of condensation and precludes catastrophic cooling of the gas. The bifurcations occur naturally, due to the shape of the radiative cooling function, and this holds for a wide range of gas metallicities. The one-zone model implies a scaling relation for the equilibrium stellar and gas densities, which allows a hydrostatic, thermally stable distribution for the hot isothermal coronal gas. The resulting model for gas recycling reproduces the basic optical and X-ray properties of relatively isolated giant elliptical galaxies with hot haloes. Implications for cD galaxies in X-ray dominant clusters and groups are briefly discussed in the general context of galaxy formation and evolution.

Modeling the Q-cycle mechanism of transmembrane energy conversion​

Anatoly Yu. Smirnov, Franco Nori
The Q-cycle mechanism plays an important role in the conversion of the redox energy into the energy of the proton electrochemical gradient across the biomembrane. The bifurcated electron transfer reaction, which is built into this mechanism, recycles one electron, thus, allowing to translocate two protons per one electron moving to the high-potential redox chain. We study a kinetic model of the Q-cycle mechanism in an artificial system which mimics the bf complex of plants and cyanobacteria in the regime of ferredoxin-dependent cyclic electron flow. Using methods of condensed matter physics, we derive a set of master equations and describe a time sequence of electron and proton transfer reactions in the complex. We find energetic conditions when the bifurcation of the electron pathways at the positive side of the membrane occurs naturally, without any additional gates. For reasonable parameter values, we show that this system is able to translocate more than 1.8 protons, on average, per one electron, with a thermodynamic efficiency of the order of 32% or higher.
