University of Texas at Dallas scientists are investigating how structures made from several layers of graphene stack up in terms of their fundamental physics and their potential as reconfigurable semiconductors for advanced electronics.

The researchers, led by the University of Cambridge and the Eindhoven University of Technology, have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such as spintronics and quantum computing.

Researchers at Tohoku University, the University of Manchester, and Osaka University have made a breakthrough that has the potential to ignite the development of next-gen chiral information technology.

Researchers at Mainz University verified the chiral-induced spin selectivity effect, i.e., the influence of chiral molecules on spin, using spintronic analytical techniques

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.

In organic molecules an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process where an exciton is amplified, and two triplet excitons are generated from a singlet exciton. This is caused by the absorption of a single particle of light, or photon, in molecules called chromophores (molecules that absorb specific wavelengths of light). Controlling the molecular orientation and arrangement of chromophores is crucial for achieving high SF efficiency in materials with strong potential for optical device applications.

The strength of a coupling between nuclear spins depends on chirality, or handedness, of the molecule, according to a new study by researchers at UCLA, Arizona State University, Penn State, MIT and Technische Universität Dresden. The study also revealed that in chiral molecules of a given handedness – whether it is a left- or right-handed molecule – the nuclear spin tends to align in one specific direction. In molecules with the opposite chirality, such as right-handedness, the spin aligns in the opposite direction.

In a study titled „Near-complete chiral selection in rotational quantum states" published in Nature Communications, the Controlled Molecules Group from the Molecular Physics Department of the Fritz Haber Institute has made a significant leap forward in the field of chiral molecules. The team, led by Dr. Sandra Eibenberger-Arias, achieved near-complete separation in quantum states for these essential components of life.

A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact in pharmaceutical science, security, forensics, environmental science, art conservation and medicine.

Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons. The electrons are shaped into chiral coils of mass and charge.
