The Higgs boson, ten years after its discovery

Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard ...

Quantum simulator shows how parts of electrons move at different speeds in 1D

A quantum simulator at Rice University is giving physicists a clear look at spin-charge separation, the quantum world's version of the magician's illusion of sawing a person in half.

A model that can predict the exact quasi-particle properties of heavy Fermi polarons

Physicists studying quantum many-body physics very rarely reach exact solutions or conclusions, particularly in more than one dimension. This is also true for the Fermi polaron problem, describing instances in which the many-body ...

Observation of fractional exclusion statistics in quantum critical matter

A quantum system consisting of a large number of microscopic particles obeys statistical laws at the macroscopic level. In nature, there are two kinds of microscopic quantum particles. One is the boson satisfying the Bose-Einstein ...

New study reveals topological charge-entropy relation in kagome Chern magnet

Topological charge-entropy scaling relation was proved in the kagome Chern magnet, a kind of magnet predicted to support intrinsic Chern quantum phases, according to a study published on Nature Communications.

Mutating quantum particles set in motion

In the world of fundamental particles, you are either a fermion or a boson but a new study from the University of Cambridge shows, for the first time, that one can behave as the other as they move from one place to another.

Kinks, skinks and supersymmetry

Supersymmetry is symmetry of nature that is often hypothesized to exist among elementary particles. In a new paper that appeared in Physical Review Letters this week, physicists from the University of Amsterdam and QuSoft ...

Rare Kondo phenomenon found in transition metal oxide, furthering decade-long debate

As temperature decreases, so does the electrical resistance of metals—most of the time. In metal with magnetic impurities, electrical resistance can increase as the temperature drops due to a strange phenomenon called the ...
