CCNY Quantum Breakthrough May Lead to Sustainable Chiral Spintronics
A team of physicists led by The City College of New York’s Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal -- a topological material where electrons mimic massless particles called Weyl fermions. These particles are distinguished by their chirality or “handedness” linked to their spin and momentum.

Identifying the Origin of Long-Period Electrical Instability in Silicon Qubit Devices
Researchers at AIST, in collaboration with Tokyo Denki University, have identified the origin of long-period electrical instability in silicon qubit devices for the first time. It is well known that the electrical characteristic of qubits, which are the basic elements of quantum computers, is not always kept constant and it changes over periods of a few tens of seconds or hours.
Beyond Fermions and Bosons: Paraparticles Are Indeed Mathematically Possible
Beyond Fermions and Bosons: Paraparticles Are Indeed Mathematically Possible
Researchers from the Max Planck Institute of Quantum Optics and Rice University have investigated the intricacies of particle exchange statistics and shown that a third category — paraparticles — can exist under specific physical conditions, obeying exotic "parastatistics" markedly different from those of fermions and bosons. Using a second quantization framework, they mathematically demonstrated that paraparticles emerge as quasiparticle excitations in quantum spin models, challenging long-standing assumptions in condensed matter and particle physics. Their discovery was published last week in Nature.

Researchers Uncover Strong Light-Matter Interactions in Quantum Spin Liquids
In a paper recently published in Nature Physics, an international group of researchers comprised of an experimental team from Switzerland and France and theoretical physicists in Canada and the U.S., including Rice University, have found evidence of this enigmatic quantum spin liquid in a material known as pyrochlore cerium stannate. They achieved this by combining state-of-the-art experimental techniques, including neutron scattering at extremely low temperatures, with theoretical analysis. By measuring the way in which neutrons interact magnetically with the electron spin in pyrochlore, the researchers observed the collective excitations of spins interacting strongly with lightlike waves.
