Spontaneous magnetization in a non-magnetic interacting metal
Over the past decade, numerous physics studies have explored how oscillating electric fields produced by lasers or microwave sources can be used to dynamically alter the properties of materials on demand. In a new study featured in Nature Physics, two researchers at...
Study gathers the first observation of leptonic decay D+→τ+ντ
The Beijing Spectrometer III (BESIII) collaboration, a large team of researchers from universities worldwide conducting particle physics studies has recently reported the first observation of the leptonic decay D+→τ+ντ. This observation, presented in a paper published...
Producing dissipative coupling in hybrid quantum systems
Introducing quantum convolutional neural networks
Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics problems is far more challenging due to the...
Measuring light and vacuum fluctuations from a time flow perspective
Some of the greatest unanswered questions about the nature of the universe are related to light, the vacuum (i.e. space where neither matter nor radiation exists), and their relationship with time. In the past, physicists and philosophers have addressed a variety of...
Measuring temperatures similar to those occurring in star collisions in the lab
Collisions between neutron stars are fascinating cosmic events that lead to the formation of numerous chemical elements. Temperatures during these collisions are exponentially high, typically reaching up to hundreds of billions of degrees Celsius.
Molecular hydrogen becomes semimetallic at pressures above 350 GPa
According to condensed matter physics predictions, at a high enough pressure, hydrogen should dissociate and transform into an atomic metal. However, the exact pressure range at which this occurs has not yet been ascertained, and the process through which hydrogen...
Near ground-state cooling of 2-D trapped ion crystals
Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such oscillators.
Numerical evidence for the merger of MOTSs inside a binary black hole
Researchers at the Max Planck Institute for Gravitational Physics, Rochester Institute of Technology and the Perimeter Institute for Theoretical Physics have recently gathered strong numerical evidence for a new phenomenon that takes place in the interior of binary...
