Now, a study co-led by Nanyang Asst Prof Su Rui from NTU’s School of Physical and Mathematical Sciences (SPMS) and School of Electrical and Electronic Engineering, as well as Assoc Prof Timothy Liew from SPMS, has shown that polaritons could be manipulated at room temperature when they are created.
Particle That Only Has Mass When Moving in One Direction Observed for First Time
Particle That Only Has Mass When Moving in One Direction Observed for First Time
For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac fermion, was first theorized 16 years ago, but was only recently spotted inside a crystal of semi-metal material called ZrSiS. The observation of the quasiparticle opens the door to future advances in a range of emerging technologies from batteries to sensors, according to the researchers. The team, led by scientists at Penn State and Columbia University, recently published their discovery in the journal Physical Review X.

Building a Safer and More Affordable Nuclear Clock
Reported recently in a new study published in Nature, a team of researchers, led by JILA and NIST Fellow and University of Colorado Boulder Physics professor Jun Ye, in collaboration with Professor Eric Hudson’s team at UCLA’s Department of Physics and Astronomy, have found a way to make nuclear clocks a thousand times less radioactive and more cost-effective, thanks to a method creating thin films of thorium tetrafluoride (ThF4).

From Waste Heat to Quantum Innovation: Advancing Spintronics
What if the waste heat generated by cars, factories, and even your laptop could be used to realize the next generation of energy-efficient quantum computers? Researchers at Illinois State University, in collaboration with the Air Force Research Laboratory (AFRL), have discovered an effect that may make that possible.
Researchers Succeed in Controlling Quantum States in a New Energy Range
Researchers Succeed in Controlling Quantum States in a New Energy Range
An international team of scientists headed by Dr. Lukas Bruder, junior research group leader at the Institute of Physics, University of Freiburg, has succeeded in producing and directly controlling hybrid electron-photon quantum states in helium atoms. To this end, they generated specially prepared, highly intense extreme ultraviolet light pulses using the FERMI free electron laser in Trieste, Italy. The researchers achieved control of the hybrid quantum states using a new laser pulse-shaping technique. Their results have been published in the journal Nature.
Anomalous Magnetic Moment of the Muon: New Calculation Confirms Standard Model of Particle Physics
Anomalous Magnetic Moment of the Muon: New Calculation Confirms Standard Model of Particle Physics
The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut Wittig of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) has calculated this quantity using the so-called lattice quantum chromodynamics method (lattice QCD method). Their result, which was recently published, agrees with the latest experimental measurements, in contrast to earlier theoretical calculations. After the experimental measurements had been pushed to ever higher precision in recent years, attention had increasingly turned to the theoretical prediction and the central question of whether it deviates significantly from the experimental results and thus provides evidence for the existence of new physics beyond the Standard Model.
