Unveiling the Hidden Stresses in Our Universe

Stress influences everything in our universe, not just in personal lives but at the very fabric of matter itself. When heavy vehicles traverse a bridge, engineers must account for the immense stress those vehicles impose. Similarly, the life and brightness of stars hinge on internal stresses. But what about protons, the building blocks of atoms? What stresses are hidden within them?

A Revolutionary Approach to Subatomic Stress Measurement

Researchers at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility are probing this question. Postdoctoral fellow Adam Freese is pioneering a fresh method to analyze stress at the quantum level, bridging the gap between classical mechanics and quantum physics.

Understanding Stress in Proton Dynamics

At Jefferson Lab, scientists have been meticulously studying how protons experience stress when subjected to varying forces. By investigating these internal stresses, they're uncovering more about the interactions between protons’ constituent particles: quarks and gluons. This knowledge could significantly enhance our understanding of how these particles shape the universe.

From Classical to Quantum: A New Perspective

The concept of stress originates in classical mechanics, which typically examines macroscopic systems. However, Freese's work applies quantum mechanics to provide an intricate view of atomic stress. In his groundbreaking paper published in Physical Review D, he calculated the stresses in a hydrogen atom, revealing how measurements of these stresses might unveil the forces at play within quarks and gluons.

Proof of Principle: The Spark of Innovation

This journey began back in 2021 when Freese discussed quantum stresses in an online forum. Skepticism from peers led him to propose starting with the simple hydrogen atom—an iconic system in quantum mechanics. Collaborative calculations further paved the way for this innovative research, demonstrating its viability and moving beyond traditional quantum mechanics.

Pilot Wave Theory: A Game-Changer in Quantum Calculations

Freese's use of pilot wave theory—an interpretation of quantum mechanics—set his work apart. Unlike conventional methods, which provide vague insights, pilot wave theory offers a clear picture of particles' movements. He asserts that, contrary to popular belief, this theory is compatible with quantum mechanics and can enhance our comprehension of stresses at the subatomic level.

Visualizing Hydrogen: Insights into Subatomic Relationships

Through his calculations, Freese discovered that in hydrogen, the electron and proton maintain a stable relationship, akin to a keystone in an arch. The forces exerted by the pilot wave on the electron balance out the electrostatic attraction, explaining the atom’s stability.

A New Frontier in Probing Fundamental Forces

Freese's research not only explains existing interactions but opens a door to future discoveries. By measuring stress in hydrogen, scientists can calculate the forces exerted by pilot waves, leading to a deeper understanding of atomic structure. He envisions applying this methodology to protons, potentially discerning the forces acting on individual quarks.

What's Next? Exploring More Complex Atomic Structures

Having laid the groundwork, Freese is eager to extend his findings to more intricate systems, such as the nucleus of deuterium, an isotope of hydrogen. Through these explorations, he aims to reveal the binding forces that hold protons and neutrons together, unraveling further mysteries of our universe.

As research continues, the potential to decode the stresses within protons poses an electrifying prospect for atomic physics, promising to reshape our understanding of the very elements that constitute our world.
