  • Quantum tunneling mystery solved after 100 years—and it involves a surprise collision
    For the first time ever, scientists have watched electrons perform a bizarre quantum feat: tunneling through atomic barriers by not just slipping through, but doubling back and slamming into the nucleus mid-tunnel. This surprising finding, led by POSTECH and Max Planck physicists, redefines our understanding of quantum tunneling—a process that powers everything from the sun […]
  • Decades of chemistry rewritten: A textbook reaction just flipped
    Penn State researchers have uncovered a surprising twist in a foundational chemical reaction known as oxidative addition. Typically believed to involve transition metals donating electrons to organic compounds, the team discovered an alternate path—one in which electrons instead move from the organic molecule to the metal. This reversal, demonstrated using platinum and palladium exposed to […]
  • You’ve never seen atoms like this before: A hidden motion revealed
    A pioneering team at the University of Maryland has captured the first-ever images of atomic thermal vibrations, unlocking an unseen world of motion within two-dimensional materials. Their innovative electron ptychography technique revealed elusive “moiré phasons,” a long-theorized phenomenon that governs heat, electronic behavior, and structural order at the atomic level. This discovery not only confirms […]
  • This Algorithm Just Solved One of Physics’ Most Infamous Problems
    Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and solve the long-standing polaron problem, unlocking deeper understanding of electron flow in tricky materials.
  • A simple twist unlocks never-before-seen quantum behavior
    Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction dramatically expands the moiré toolkit and may soon lead to the experimental realization of long-sought quantum spin liquids.
  • Scientists just recreated a 1938 experiment that could rewrite fusion history
    A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur Ruhlig, a little-known physicist, first observed signs of deuterium-tritium (DT) fusion nearly a decade before its significance became clear in nuclear science. The modern team not only […]

Exchange interaction

Electrons prefer parallel spins due to the quantum mechanical concept of exchange energy, which lowers their system's total energy. This preference is a result of the Pauli exclusion principle and the antisymmetric nature of fermion wavefunctions, reducing Coulomb repulsion and stabilizing the system in quantum mechanical interactions.
