A quantum simulator has given physicists a new look at one of the strangest ...

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics ...

The Observer Effect and Quantum MechanicsIn Episode 5, we looked at the horizon of the "multiverse" depicted by eternal ...

Theoretical physicists routinely introduce fictitious particles and fields in their calculations, in view of completing a theory or simply to make it more elegant. A striking example concerns the ...

In quantum field theory, spontaneous particle formation can occur when the potential energy between two elementary particles increases with their separation, as if they were confined by a string. When ...

In light of the recent criticisms of string theory, preeminent physicist Juan Maldacena sheds light on the promise of string theory and how it fits into our current understanding of the universe. In ...

Researchers used 13 trapped ions to simulate string breaking, showing how quantum hardware could help scientists explore ...

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...
