Designing lasers based on quantum physics  PHYS.ORG · 1 week
A five-country research team coordinated by Germán J. de Valcárcel Gonzalvo, Professor of Optics at the University of Valencia, has developed a new theory —the coherent master equation— that describes the behavior of pulsed lasers based... more
Why Has String Theory Persisted?  LIVE SCIENCE · 2 weeks
String theory is a powerful idea, unfinished and untested, but one that has persisted for decades despite inauspicious beginnings. more
New classes of topological crystalline insulators having surface rotation anomaly  PHYS.ORG · 2 weeks
In a new report on Science Advances, Chen Fang and Liang Fu from the Beijing National Laboratory for Condensed Matter Physics in China, Kavli Institute for Theoretical Sciences... more
Hubble Uses Quadruple-Image Gravitational Lenses to Capture Small-Scale Clumps of Dark Matter  SCI-NEWS.COM · 3 weeks
According to the widely-accepted ‘cold dark matter’ theory, all galaxies are embedded within clouds of dark matter. Dark matter itself consists of slow-moving particles... more
Water could disappear from Mars faster than expected  PHYS.ORG · 3 weeks
Mars is losing water more quickly than theory and observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars as sunlight and chemistry disassociate water molecules... more
Intrinsic quantized anomalous Hall effect in a moiré heterostructure  PHYS.ORG · 3 weeks
The quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields). In a... more
A neural network as an anchor point  PHYS.ORG · 3 weeks
Quantum mechanics is a well-established theory, but at a macroscopic level it leads to intractable contradictions. Now ETH physicists are proposing to resolve the problem with the aid of neural networks. more
Nearly quantized conductance plateau of vortex mode in an iron-based superconductor  PHYS.ORG · 4 weeks
When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero... more
The experimental demonstration of a spin quantum heat engine  PHYS.ORG · 4 weeks
The theoretical notion of a 'quantum heat engine' has been around for several decades. It was first introduced around sixty years ago by Scovil and Schulz-DuBois, two physicists at Bell... more
