Deep Learning with Quantum Fields

Recent developments in Quantum Physics, in particular in Quantum Field Theory, suggest the surprising possibility that electromagnetic and matter quantum fields can store and elaborate information, thus expressing learning abilities, typical of neural networks.

The Nonlocality of Life – Part 1

What’s Life? 
I've found a nice paper where the Author, Donald C. Mikulecky, has argued that “Such a question is inherently ill posed. Instead, we ask to distinguish life from not-life and, in particular, a machine”.
The paper (available elaborates on the amazing findings of the theoretical biologist Robert Rosen, who remarkably has taken this new perspective for studying life.
“If it were necessary to try to characterize in a few words the difference between living organisms and inorganic systems, such a characterization would not involve the presence of DNA, or any other purely structural attributes; but rather that organisms constitute the class of systems which can behave in an anticipatory fashion (Robert Rosen)”.
As Rosen explains: "Systems that behave as true anticipatory systems, systems in which the present state changes according to future states, violate the law of classical causality according to which changes depend s…

It's a matter of light

The refractive index of a cell is a key biophysical parameter, correlated with the biophysical status (e.g., level of health) of the cell including mechanical, electrical and optical properties.
The refractive index provides also other valuable information about the intracellular mass and concentration of the cell. It has been intensively studied and several techniques have been developed to measure it.
Look at this nice paper “Cell refractive index for cell biology and disease diagnosis: past, present and future” available at this link:
The Authors provide an overview of cell refractive index models and measurement techniques including microfluidic chip-based techniques for the last 50 years.Moreover, the paper presents the applications and significance of cell refractive index in cell biology, hematology, and pathology, and discusses future research trends in the field, including 3D imaging methods, integrat…

What is Life ? - Part 2

These equations are expressing electric E and magnetic H fields in terms of potentials: A is the magnetic vector-potential and Ao is the scalar electric potential. There are studies and experimental evidences showing that electromagnetic potential plays a fundamental role on the emergence and development of coherent structures in matter.
Different choices of A and Ao can be consistent with given observable electric and magnetic fields E and H: in other words, the potentials can be changed by a gauge transformation as without changing the electric and magnetic field. This is remarkable characteristics as one may act on the phase without changing the electric and magnetic fields.
For instance, for every scalar function of position and time λ (x, t), two pairs of gauge transformed potentials (Ao, A) and (Ao′, A′) are called gauge equivalent, and the so-called gauge freedom allow to select any pair of potentials in its gauge equivalence class:

Another characteristic of potentials which is not…

What is Life ? - Part 1

The attempts of applying quantum physics to living organisms started soon after the birth of Quantum Mechanics (QM). One of the first remarkable examples is when E. Schrodinger, in 1944, wrote his book “What is life? ”.
Today QFT is offering new thought categories (not present in QM) for applying quantum physics to life. Specifically, Nambu-Goldstone bosons (not present in QM), in my opinion, represent these new powerful concept (experimentally validated), in that direction.
We recall that in QFT, Nambu-Goldstone bosons are massless quasi particles associated with the spontaneous breakdown of symmetry.
For instance, in the case of a crystal, the phonons are Nambu-Goldstone bosons which can be imagined as elastic waves through which the atoms "communicate", i.e., exchange the ordering information. In the case of a magnet, the Nambu-Goldstone bosons are called magnon quasi-particles or the spin-wave modes.
As bosons (not fermions), they can occupy the same state with the same qu…

Gauge Theory and Biological Intelligence

The Gauge theory, within the context of the QFT and the Standard Model, describes interactions and energy exchanges between quantum particles and their associated wave fields.

The main characteristic of the Gauge theory mathematical framework is the presence of a group of transformations of the field variables (called gauge transformations) that leaves the basic physics of the field unchanged (called gauge invariance). In other words, the Lagrangian of a system (i.e., a function that summarizes the system’s dynamics) is invariant under a continuous group of local transformations. The global symmetry of the system is preserved, despite local changes, by a continuous force, called the gauge field. The Lagrangian is kept invariant under continuous symmetry transformations, being the gauge fields sort of compensatory fields introduced to maintain said symmetry.
Amazingly, even if Gauge theory originate from physics, it is valid also in other fields, even in biology. Common to all these fi…

Symmetry States of the Physical Space

With this post, we’d like to draw the attention on this paper (Symmetry States of the Physical Space: An Expanded Reference Frame for Understanding Human Consciousness).
Please take some time to read it carefully with an open-minded approach. The core question addressed by the paper is: what is the nature of the actual energies radiating from relics of the historical Buddha?
In any Culture, a relic is some remains of great spiritual significance, capable of inducing strong emotions in most people. Is it just a subjective impression or is there a subtleenergy belonging to a higher reality? If so Physics may give some important clues as to the nature of this higher reality.
Interestingly, the paper describes experiments and a theory developed by the team of W. Tiller, Emeritus of Stanford University Department of Materials Science and Engineering. The key point is that “any physical measurement quantitatively consists of two parts, one from U(1) gauge state and one from SU(2) gauge state w…
