Could you clarify — by QFT model, do you mean:

Quantum Field Theory (QFT) in physics — the framework unifying quantum mechanics and special relativity, used to describe particles as excitations of underlying fields (e.g., Standard Model of particle physics)?
Or Mani Bhaumik’s interpretation of QFT (in Code Name God), where he talks about the “primary field” that science is approaching, which he likens to a spiritual foundation of the universe?

(1) QFT in Physics: The Standard Model

Quantum Field Theory (QFT): A mathematical framework where particles are seen as excitations (“quanta”) of underlying fields.
Core Features:
- Unifies quantum mechanics + special relativity.
- Uses creation and annihilation operators on quantum states.
- Includes interactions via gauge symmetries.
Standard Model of particle physics = the most successful QFT model to date.
- Gauge group: SU(3) × SU(2) × U(1).
- Fields: quark fields, lepton fields, gauge boson fields, Higgs field.
- Predicts electromagnetic, weak, and strong interactions.
- Verified experimentally (LHC, neutrino oscillations, Higgs boson discovery 2012).

(2) Mani Bhaumik’s QFT Spiritual Parallel

In Code Name God, Bhaumik uses Quantum Field Theory to draw parallels with spirituality:

He points to the quantum vacuum / primary field, the source from which matter and energy arise.
Suggests this could be seen as a scientific analog of Brahman (ultimate reality in Vedanta).
In his view, consciousness and material reality emerge from this unified field.

Example (from his writings/excerpts):

“Physics is close to proving that material reality emerges from a common source, which I’ll refer to as the primary field. Is this the field where God has been at play all along?”

👉 Do you want me to dive deeper into the technical QFT framework (with equations & models), or the Bhaumik / philosophical interpretation of QFT?

The puzzle that Einstein was not able to solve, but contemporary physicists

are close to putting together, is this: Why, if everything is made of one

substance—energy—does nature require so many different fields for energy

to work its magic? Most physicists are now pretty convinced that these

diverse quantum fields, although essential for manifestation, are nothing but

different aspects of a single primary field, which I like to call the source (at

least of everything that can be called physical)

Nice passage — that’s basically the modern restatement of Einstein’s puzzle: if everything is “energy” (or excitations of fields), why do we need a whole zoo of different quantum fields instead of one underlying thing? Below I’ll unpack that in plain language, then summarize how contemporary physics is trying to put the pieces together (with citations).

The puzzle in one sentence

We observe many particle types and forces → in QFT each particle type is an excitation of its own field. Einstein’s question: if nature is one deep “stuff,” why do we need many distinct fields rather than a single field whose different behaviors produce all observed particles and forces?

How modern physics frames the answer

Fields vs. excitations.
In QFT the fundamental objects are fields that fill spacetime; particles are just quanta (excited states) of those fields. Different particle species correspond to different fields or different modes of fields. That’s the language of the Standard Model. (Stanford Encyclopedia of Philosophy)
Symmetries and gauge structure.
The diversity of fields arises from underlying symmetry principles (gauge groups). The Standard Model’s structure (SU(3)×SU(2)×U(1)) organizes different fields and interactions. If a larger symmetry existed at high energy, the many low-energy fields might be understood as broken remnants of one bigger structure. That’s the idea behind Grand Unified Theories (GUTs). (Particle Data Group)
Spontaneous symmetry breaking (Higgs mechanism).
A single high-symmetry theory can look like many distinct forces and particles at low energy because the symmetry is spontaneously broken (the Higgs field giving masses is the classic example). So “many fields” at our energies can be different aspects of a unified high-energy theory. (Particle Data Group)
Vacuum / primary field idea.
QFT also tells us the vacuum is not empty — it’s a seething state with zero-point energy, condensates and structure (vacuum expectation values). Some thinkers (and authors like Mani Bhaumik) use this to motivate a single “primary field” or source from which observable fields and matter emerge: the vacuum/field structure is the progenitor of manifest physics. Technically, different condensates and field excitations produce the diversity we see. (Wikipedia)

Where physicists are now (current status and limits)

Partial success (unification of electroweak): The electroweak unification (Glashow–Weinberg–Salam) is a real example where seemingly different forces are unified into one framework and then split at low energy. This is a proof-of-concept for the “one → many” idea. (Wikipedia)
GUTs are plausible but unproven: Grand Unified Theories extend this idea to include the strong force; they predict new phenomena (e.g., proton decay) that haven’t been observed yet, so GUTs remain hypotheses. (Particle Data Group)
Gravity resists unification: Incorporating gravity (general relativity) into the quantum-field framework is an open problem (quantum gravity). That’s why a true “theory of everything” is still missing. Reviews of progress and options (string theory, loop quantum gravity, etc.) are active research areas. (Cosmos)
Experimental constraints are tightening: Ideas that looked promising (like weak-scale supersymmetry), which could have helped unify fields and cancel troublesome vacuum energies, have not shown up at the LHC so far — experiments have placed strong limits and forced theorists to revise or move scales. That doesn’t disprove unification in principle, but it makes some scenarios less likely. (arXiv)

Two useful metaphors

One tree, many branches: A single high-energy theory (the trunk) can produce many low-energy phenomena (branches and leaves) through symmetry breaking and different excitation patterns.
Musical instrument: The same underlying string (or field) can produce different notes (particle types) depending on how it vibrates — except in real physics there may be many different “strings/fields” or modes, and the challenge is to show they’re all modes of one underlying object.

Open technical problems that keep this “puzzle” alive

Finding experimental evidence for GUT predictions (e.g., proton decay). (Particle Data Group)
Explaining why the vacuum energy (zero-point energy) doesn’t gravitate as naïve QFT predicts (the cosmological constant problem). (Wikipedia)
Merging quantum theory with gravity into a consistent framework where spacetime and fields emerge from a single underlying principle. (Cosmos)

If you want, I can:

Give a compact math sketch (Lagrangian → symmetry group → spontaneous breaking → multiple effective fields).
Walk through specific unification proposals (SU(5), SO(10), string theory) and what experiments say about them today.
Explain the vacuum energy / cosmological constant problem in more depth (why QFT predicts a huge vacuum energy and why that’s a problem).
