Renormalization subtracts infinite energy by hand - can we ask where exactly: what is subtracted density? Discussion of such its shifting to regularization, translating Feynman diagrams to corresponding field configurations: zenodo.org/records/2329...

AI helped us explore nuclei as energy-minimizing 3D field configurations: candidates with gluon flux tube as topological-vortex structures, and red/blue charge halos. Paper v4.7: zenodo.org/records/2326... #physics #ai

A photon that would never be absorbed, in CPT perspective, would never have been emitted. So photons we emit need absorbers in our future - which an accelerating open Universe lacks for above 98.5% of emitted - a sharp argument for a Big Crunch in our future: zenodo.org/records/2320... #physics

Black-hole interiors from both ends: a horizon hides its interior from signals, not from exchange. Read forward for black holes, backward for white holes: 9 interiors vs the data that separate them. doi.org/10.5281/zeno... #physics #astronomy

Grok response: x.com/grok/status/... "No existing dataset fully rules out active BH cooling as a CPT complement to inverse Compton. Your table flags some constraints as disfavored or nominal, others untested (e.g. Partridge GC direction). Distinction needs the horizon controls or lab tests you list"

If a white hole actively heats what's around it, its time mirror — a black hole — should actively cool. Data don't require it yet; here's what would decide: horizon vs neutron-star controls, switched-terminal lab tests, a spin ceiling. v2.3: zenodo.org/records/2316... #physics #astronomy

Quantum computes are believed to have higher capabilities than Turing machine, bringing question if our physics doesn't allow for even better ways? I think about it for ~20 years and just worked with topLLMs on big review: zenodo.org/records/2312...

We prepare the past but only sample the future. If CPT symmetry is taken seriously, that asymmetry is a boundary condition, and boundary conditions can be measured: a null reads as a lower bound on 'how hot the future is' for a given channel: zenodo.org/records/2310...

While we usually assume Feynman path ensembles weight all final outcomes equally, no experiment has directly tested this. It is the crucial question especially for 2WQC nextgen quantum computers - discussion with tests within reach: zenodo.org/records/2309...

At least 4 approaches for added postparation <0|, CPT analog of preparation |0>, already have experimental confirmations, however, not in actual quantum computers - what will need e.g. perfect synchronization. zenodo.org/records/2308...

Proton decay is required e.g. by baryogenesis and Hawking radiation, releasing ~1000x more energy than nuclear fission. Discussed its investigation e.g. passing proton beam through wiggler/undulator, reaching superradiance for positron Cooper pairs: zenodo.org/records/2297... #physics

GR is solved by least action principle, in QFT extended to Feynman ensembles - we just need to accept, carrying T/CPT symmetry e.g. in S-matrix <psi_f |U| psi_i> with Born rule from meeting of propagators from both time directions - allowing to violate Bell. From arxiv.org/pdf/0910.2724 :

If indeed there will be Big Crunch - hot soup similar to Big Bang, CPT-symmetry allows to evolve backward from it with the same equations - also requiring BLACK HOLES ... which turn out in good agreement with observed LITTLE RED DOTS Predicting ~87Gyr eon: zenodo.org/records/2269...

Classical computers use two-way control e.g. pushing and pulling electrons through chip ... wouldn't be very practical for one-way control: connecting to only one battery terminal. But for quantum there is now only focus on one-way control, why not try to also reach two-way? ( www.qaif.org/2wqc )

Jarek Duda @jarekduda.bsky.social · 30/08/2026
Berry's backflow (iopscience.iop.org/article/10.1...) allows to locally reverse energy flux e.g. by interfering beams- one of ways to pull with EM. Simultaneously pushing and pulling through photonic chip, could we reach two-way control this way? Below realization: iopscience.iop.org/article/10.1...

Jarek Duda @jarekduda.bsky.social · 27/08/2026
The big question is if Feynman ensembles should be of physical scenarios? Schrodinger is derived from nonphysical: diffusion-like infinite velocity paths. We can use smooth path ensembles but leading to slightly different behav.: journals.aps.org/pra/abstract... community.wolfram.com/groups/-/m/t...
010
Jarek Duda @jarekduda.bsky.social · 25/08/2026
Before advantage, maybe let's catch up with classical - e.g. pushing and pulling electrons through chip. In contrast, current quantum are focused on one-way control ... also reaching two-way would greatly improve error resistance and correction: www.qaif.org/2wqc
