Scientists at the MAJORANA Collaboration look for rule-violating electrons

In a new study published inNature Physics, scientists at the MAJORANA Collaboration have tested the stringency of charge conservation and Pauli's exclusion principles using underground detectors. Alessio Porcelli has published ...

Research reveals a surprising topological reversal in quantum systems

In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both ...

A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations

Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying ...

Physicists track how continuous changes in dimensionality affect collective properties of a superfluid

An international research team from Innsbruck and Geneva has, for the first time, probed the dimensional crossover for ultracold quantum matter. In the regime between one and two dimensions, the quantum particles perceive ...

Rare decay of the Higgs boson may point to physics beyond the Standard Model

Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are ...

Physicists capture first sounds of heat 'sloshing' in a superfluid, revealing how heat can move like a wave

In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave ...

Team shows how uranium ditelluride continues superconducting even in high magnetic fields

Superconductivity is well understood in so-called "conventional" superconductors. More recent, however, are unconventional superconductors, and it is as yet unclear how they work.
