It is not always easy to find a good fit at an excellent research institution. If you are considering doing a #PhD or #Postdoc in #mathematics #particlephysics #theoreticalphysics or #astrophysics we have you sorted in Hamburg. This workshop is a way to get to know our Cluster of Excellence and #UniHamburg/#DESY groups on those topics, just before we start hiring this year. Check it out!
Mary K Gaillard, Who Broke a Ceiling in Subatomic Research, Dies at 86
Overcoming discrimination in a mostly male preserve, she did groundbreaking work that showed experimentalist physicists where and how to look for new particles.

ScienceDailyBuilding electronics that don’t die: Columbia's breakthrough at CERNDeep beneath the Swiss-French border, the Large Hadron Collider unleashes staggering amounts of energy and radiation—enough to fry most electronics. Enter a team of Columbia engineers, who built ultra-rugged, radiation-resistant chips that now play a pivotal role in capturing data from subatomic particle collisions. These custom-designed ADCs not only survive the hostile environment inside CERN but also help filter and digitize the most critical collision events, enabling physicists to study elusive phenomena like the Higgs boson.

ScienceDailyGhost particles may secretly decide the fate of collapsing starsNeutrinos, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New research suggests that as stars collapse, they form natural "neutrino colliders," allowing scientists to probe these elusive particles in ways never possible on Earth. If neutrinos do interact through yet-undiscovered forces, they could cause stars to collapse into black holes instead of neutron stars, reshaping how we understand cosmic evolution.

In a paper posted today, led by #UCIrvine PhD student Cannon Vogel, we showed that the newly allowed large cosmological lepton numbers at early times open up a new regime of sterile neutrino dark matter production. The results are of interest for warm dark matter at the ~10 keV scale, with hard X-ray astronomical observatories sensitive to this parameter space.

ScienceDailyYou’ve never seen atoms like this before: A hidden motion revealedA 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 decades-old theories but also provides a new lens for building the future of quantum computing, ultra-efficient electronics, and advanced nanosensors.
Quantum Entanglement
Quantum physics is fascinating.
Quantum Entanglement is the phenomenon where the quantum state of each particle in a group cannot be described independently of the state of the others, even when the particles are separated by an astronomical large distance. The topic of quantum entanglement is at the heart of the disparity between classical physics and quantum physics: entanglement is a primary feature of quantum mechanics not present in classical mechanics.
Measurements of physical properties such as position, momentum, spin, and polarization performed on entangled particles can, in some cases, be found to be perfectly correlated. For example, if a pair of entangled particles is generated such that their total spin is known to be zero, and one particle is found to have clockwise spin on a first axis, then the spin of the other particle, measured on the same axis, is found to be anticlockwise. However, this behavior gives rise to seemingly paradoxical effects: any measurement of a particle's properties results in an apparent and irreversible wave function collapse of that particle and changes the original quantum state. With entangled particles, such measurements affect the entangled system as a whole.

Quantum levitation isn't just a cool phenomenon, it's only possible when things are so cold that your material superconducts in a special (type II) way
Big ThinkThe incredible physics of quantum levitationWith the right material at the right temperature and a magnetic track, physics really does allow perpetual motion without energy loss.
