Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her journey to connect with ...

Understanding quantum mechanics with active particles

Physicists led by Prof Raphael Wittkowski and Prof Uwe Thiele from the Institute of Theoretical Physics at the University of Münster has developed a new model for the dynamics of systems consisting of many self-propelled ...

Quantum chemistry: Molecules caught tunneling

Tunneling reactions in chemistry are difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. ...

The quantum twisting microscope: A new lens on quantum materials

One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. In a new study, reported today in Nature, researchers from the ...
