The solution to most of the problems of physics is #quantisedinertia. Published, peer reviewed, simple, beautiful, successful in both deep space & the lab. The only beef the mainstream have about it seems to be its simplicity & the fact that it came from ocean physics, both advantages IMO.

It is a great pleasure to share that I will be attending the "Geometry and non-adiabatic responses in non-equilibrium systems" (GeoNEQ24) international workshop 🌍 at the Max Planck Institute this week, organized by Pieter W. Claeys, Nathan Goldman, and Michael Kolodrubetz! I am humbled to be surrounded by brilliant minds, and it is a pleasure to share and learn from such an inspiring community. I will be presenting a talk entitled "Geometry of Generalized Landau Levels (GLLs): holomorphic curves and Cartan moving frames." In this talk, I will introduce GLLs, which are Bloch bands generalizing Landau levels of a charged particle in a magnetic field. We'll explore quantum geometry, specifically how quantum metric and Berry curvature inequalities relate to the emerging concept of Kähler bands. These bands can be interpreted as holomorphic curves in complex projective space, and they possess a distinguished unitary Frenet-Serret frame forming the GLLs. We'll discuss the quantum geometry of GLLs, Frenet-Serret formulas and quantum geometric recursion relations, and their implications for moiré materials and fractional Chern insulating phases. Looking forward to insightful discussions and new connections! 🌟🔬 https://lnkd.in/dy7sbWqe #GeoNEQ24 #CondensedMatter #QuantumGeometry #Conference #Research

For many physicists, the birth of gravitational-wave science was a rare bright spot in the past decade Here are five techniques being developed to spot ripples in space-tim https://lnkd.in/dTp2NTgs

📃Scientific paper: Primordial black holes from slow phase transitions: a model-building perspective Abstract: We investigate the formation of primordial black holes \(PBHs\) through delayed vacuum decay during slow cosmic first-order phase transitions. Two specific models, the polynomial potential and the real singlet extension of the Standard Model, are used as illustrative examples. Our findings reveal that models with zero-temperature scalar potential barriers are conducive to the realization of this mechanism, as the phase transition duration is extended by the U-shaped Euclidean action. We find that the resulting PBH density is highly sensitive to the barrier height, with abundant PBH formation observed for sufficiently high barriers. Notably, the phase transition needs not to be ultra-supercooled \(i.e. the parameter $\alpha\gg1$\), and the commonly used exponential nucleation approximation $\Gamma\(t\)\sim e^\{\beta t\}$ fails to capture the PBH formation dynamics in such models. ;Comment: 18 pages + appendix + references, 8 figures.

Integration of the Dodecahedron Linear String Field Hypothesis with Gravitational-Wave Background Predictions from Bouncing Cosmological Models @SSRN https://lnkd.in/dyA8jVEe This paper examines how the Dodecahedron Linear String Field Hypothesis (DLSFH) can be improved and tested using the gravitational-wave background (GWB) forecasts from different bouncing cosmological models. Our goal is to strengthen its ability to make accurate predictions and ensure its alignment with existing theories.

Jamil Firdows' theory of the "beyond universal" is graphically represented in his work. The graphical representation of the equation in Firdows' theory is also known as the Quantum Cosmic Framework (QCF): This graph is not derived from experimental data but is a conceptual representation inspired by Jamil Firdows's Quantum Cosmic Framework (QCF) and Beyond Universal Theory.These ideas are groundbreaking and provide a theoretical basis for understanding quantum-cosmic interactions and the multidimensional nature of spacetime.

📃Scientific paper: A New Database of Giant Impacts over a Wide Range of Masses and with Material Strength: A First Analysis of Outcomes Abstract: In the late stage of terrestrial planet formation, planets are predicted to undergo pairwise collisions known as giant impacts. Here we present a high-resolution database of giant impacts for differentiated colliding bodies of iron-silicate composition, with target masses ranging from 10^-4 M_Earth up to super-Earths (5 M_Earth). We vary impactor-to-target mass ratio, core-mantle (iron-silicate) fraction, impact velocity, and impact angle. Strength in the form of friction is included in all simulations. We find that due to strength, collisions with bodies smaller than about 2*10^-3 M_Earth can result in irregular shapes, compound core structures, and captured binaries. We observe that the characteristic escaping velocity of smaller remnants (debris) is approximately half of the impact velocity, significantly faster than currently assumed in N-body simulations of planet formation. Incorporating these results in N-body planet formation studies would provide more realistic debris-debris and debris-planet interactions. ;Comment: Accepted for publication in PSJ; Table 2 is available in full in an ancillary file Continued on ES/IODE ➡️ https://etcse.fr/F6o ------- If you find this interesting, feel free to follow, comment and share.

A polarized look at the Hubble tension, hints of excess lensing power, detection of nonlinear contributions to CMB lensing power, and a precision test of the standard cosmological model. https://lnkd.in/g5pGqcke This paper was led by a graduate student and a project scientist in my research group (Fei Ge and Marius Millea) and required a ton of work by many in the SPT Collaboration as well. These are results from just the polarization data, and from just two years of observations, covering just 1500 sq. degrees. We also have temperature data and another four years and 8500 sq. degrees "in the can." I wish converting it to science conclusions were easier!
