Strong interactions between particles in physical systems can result in various highly correlated ground states. These states and the strong correlations underpinning them have been extensively explored in recent years.
The QCD vacuum (i.e., the ground state of vacuum in the quantum chromodynamics regime) is theoretically characterized by the presence of non-zero expectation values of condensates, such as gluons and quark–antiquark pairs. ...
A hallmark of so-called topological quantum states is that they are protected against local perturbations. ETH physicists now demonstrate that in the paradigmatic case of the integer quantum Hall effect, vacuum fluctuations ...

Attoclocks, or attosecond clocks, are instruments that can measure time intervals on the attosecond scale by measuring the time it takes for electrons to tunnel out of atoms. The attosecond procedure was first introduced ...
Several thousand sensors distributed over a square kilometer near the South Pole are tasked with answering one of the large outstanding questions in physics: does quantum gravity exist? The sensors monitor neutrinos—particles ...

Over the past few decades, researchers have identified a number of superconducting materials with atypical properties, known as unconventional superconductors. Many of these superconductors share the same anomalous charge ...
A team of researchers at the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory, in California, has found evidence of ions behaving differently than expected in their fusion reactions.
In recent years, physicists and material scientists have uncovered several new platforms for studying correlated phases of matter, such as superconductivity and the correlated insulator phase. Among them is magic-angle twisted ...
Over the past few decades, quantum physicists and engineers have been trying to develop new, reliable quantum communication systems. These systems could ultimately serve as a testbed to evaluate and advance communication ...
