  • 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 […]
  • This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and salt
    At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on […]
  • Self-lighting chip uses quantum tunneling to spot a trillionth of a gram
    Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in […]
  • Scientists freeze quantum motion using ultrafast laser trick
    Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.

The Bohr atom model

The Bohr model revolutionized our understanding of the atom. It proposed electrons exist in fixed energy levels, challenging classical physics. This explained the hydrogen spectrum and laid the foundation for quantum mechanics.

Ferromagnetic Resonance (FMR) spectroscopy

Ferromagnetic resonance (FMR) is a powerful tool for investigating magnetism in materials. By applying a microwave field and measuring its absorption, FMR reveals details like a material's magnetization and damping. This excerpt explores the theory behind FMR, including the Kittel formula that describes the resonance condition. We'll also delve into ...

Spin pumping: An Introductory Overview

With STT, we have seen that a current can move magnetization, but the reciprocal effect is also possible, namely the generation of a spin current by magnetization motion. This phenomenon is called spin pumping and it is essential for developing spintronic devices, which utilize the spin of electrons rather than ...

Giant (GMR) and Tunnel (TMR) magnetoresistance

Giant magnetoresistance (and later Tunnel magnetoresistance) is one of the biggest discoveries in thin-film magnetism. Within 10 years after its discovery, it was already used in commercial devices, such as hard disk drive read heads, changing the world. Just like other magnetoresistive effects, GMR is about the change in resistivity ...

Spin-Transfer Torque: An Introductory Overview

Next to the charge, electrons also posses spins. In normal electronic circuits it is of (hardly) no use, as they are orientated randomly in non-ferromagnetic materials. However, when we integrate ferromagnetic components into these devices, the itinerant electrons can become partially spin polarized, with their spins taking on a more ...

Micromagnetics – An Introductory Overview

Micromagnetics is a field in physics that deals with the behaviour of magnetics at a sub-micrometer dimension. This theory is based on the assumption that the length of the magnetization vector is constant, and that the energy varies slowly at the atomic scale. This will break down when approaching the ...

Einstein, Politics and Science

The first world war (WWI) started in august 2014, and the German army proceeded very fast through Belgium. This rapid progression created a problem in the cities that were already captured, as the main army moved on to other locations. Harsh measures were taken to avoid any kind of resistance. ...

History of Physics (1895 – 1945)

Physics has always been an interesting topic, but it was during a span of only 50 years that physics completely changed the world. The movie "Oppenheimer" showed in great detail the history of what happened and how they got to the atomic bomb. But this is only part of the ...
