Chirality induces giant charge rectification in a superconductor
16 avrilRecent studies have revealed that electrons passing through chiral molecules exhibit significant spin polarization—a phenomenon known as chirality-induced spin selectivity. This effect stems from a nontrivial coupling between electron motion and spin within chiral structures, yet quantifying it (…) -
Multivalley semiconductor enables optical switching in germanium for high-speed computing and communications
16 avrilOpaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a material. Remarkably, when the laser is switched on and off at ultrahigh speeds, the effect can be (…) -
Physicists develop compact, mid-infrared pulse generator on single chip
16 avrilPhysicists at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip. -
Study realizes symmetry-protected molecular qubits based on cold polyatomic molecules
16 avrilOver the past decades, researchers have been trying to develop increasingly advanced and powerful quantum computers, which could outperform classical computers on some tasks. To attain this, they have been trying to identify new ways to store and manipulate qubits, which are the fundamental (…) -
Magnetic force training helps AI take charge of material simulations
16 avrilAn international team of researchers has developed a new method for parameterizing machine-learning interatomic potentials (MLIP) to simulate magnetic materials, making the prediction of their properties much more reliable and accurate. A key feature of the new approach is that the models of (…)
