Hard-to-detect elementary particles, known as neutrinos, have been found to engage in unprecedented interactions with photons under extreme environmental conditions.
A study conducted at Hokkaido University has demonstrated that elusive neutrinos have the capacity to engage with photons—elementary particles that constitute light and other forms of electromagnetic radiation—in manners not identified before. The research was led by Kenzo Ishikawa, Professor Emeritus at Hokkaido University, along with his associate Yutaka Tobita, a lecturer at Hokkaido University of Science. Their findings have been published in the scholarly journal, Physics Open.
Ishikawa notes, “Our findings have significant implications for understanding the quantum interactions among some of the most basic particles in existence. Furthermore, they may shed light on presently enigmatic phenomena occurring in celestial bodies such as the sun and other stars.”

The Enigma of Neutrinos
Among elementary particles, neutrinos remain profoundly mysterious. They pose significant challenges to research efforts owing to their minimal interactions with other types of particles. They are electrically neutral and possess almost negligible mass. Nevertheless, they are remarkably prevalent, ceaselessly emanating from the sun and permeating Earth—and indeed, living beings—without noticeable impact. Gaining a deeper understanding of neutrinos is pivotal for validating or perhaps modifying the prevailing framework of particle physics, commonly referred to as The Standard Model.
Under what are considered ‘classical’ circumstances, neutrinos generally do not interact with photons. However, Ishikawa explains, “We have discovered that, in the uniform magnetic fields on an extraordinarily large scale—spanning up to 10^3 kilometers—that are prevalent in plasma around stars, neutrinos and photons can be coaxed into interacting.” Plasma is an ionized state of matter wherein atoms have either gained or lost electrons, resulting in either negatively or positively charged ions, contrasting with the neutral atoms that commonly exist under terrestrial conditions.
The Electroweak Hall Effect and Potential Ramifications
The interactions outlined by the researchers involve a theoretical construct known as the electroweak Hall effect. Here, electricity and magnetism merge under extreme conditions, blending two fundamental natural forces—the electromagnetic and weak forces—into a unified electro-weak force. This theory is thought to be applicable exclusively under the extreme energy conditions of the universe’s early moments or during collisions in particle accelerators.
The investigators have formulated a mathematical depiction of this unanticipated neutrino-photon interaction, termed the Lagrangian, which encapsulates all that is known about the system’s energy states.
Additionally, Ishikawa comments, “Beyond enhancing our grasp of fundamental physics, our discoveries may also contribute to solving the solar corona heating enigma—a long-standing question regarding why the sun’s outer atmosphere, or corona, is substantially hotter than its surface. Our findings indicate that the interactions between neutrinos and photons release energy that elevates the temperature of the solar corona.”
To conclude, Ishikawa articulates the ambitions of their research team: “We aspire to extend our investigations to gain more profound insights, particularly concerning the energy exchange between neutrinos and photons under these extreme settings.”

Just imagine the possibilities if we can manipulate interactions at the particle level. Might be looking at a new age of energy solutions.
This is some next-level science! But what’s the real-world application of this? I mean its cool, but can it be used in tech or something?
Super intrigued by the solar corona heating puzzle part. Been a mystery for so long and now there’s a chance we could actually figure it out!
can’t believe how far we’ve come in understanding these elusive particles. Makes me wonder what else we’re gonna find out next.
Wow, this is groundbreaking stuff! Never thot neutrinos could be so interesting. Anyone else thinking this could be a game changer for physics?
