網頁2024年1月20日 · Herein, we report on the synthesis and high-performance liquid chromatography (HPLC) resolution of a new atropisomeric C2-symmetry chiral monomer based on the 3,3′-bithiophene core, which was developed to produce novel, inherently oligomeric chiral electroactive materials. The analytical enantioseparation was … 網頁2014年9月2日 · The quantum anomaly enables electrical currents injected into the system parallel to an external magnetic field to drive internal “valley currents” that describe how the imbalance between Fermi points diffuses through the material.

網頁2015年10月23日 · In a Dirac semimetal, each Dirac node is resolved into two Weyl nodes with opposite "handedness" or chirality. The two chiral populations do not mix. However, in parallel electric and magnetic fields ( E: B: ), charge is predicted to flow between the Weyl nodes, leading to negative magnetoresista … 網頁The chiral anomaly are given by non-trivial BRST cohomology classes at ghost number one on the space of local functionals. We show once again that the trace anomaly of energy-momentum tensor for a chiral fermion has parity-odd term. In my opinion, we have ... In theoretical physics, a chiral anomaly is the anomalous nonconservation of a chiral current. In everyday terms, it is equivalent to a sealed box that contained equal numbers of left and right-handed bolts, but when opened was found to have more left than right, or vice versa. Such events are expected to be … 查看更多內容 The chiral anomaly originally referred to the anomalous decay rate of the neutral pion, as computed in the current algebra of the chiral model. These calculations suggested that the decay of the pion was suppressed, … 查看更多內容 The Standard Model of electroweak interactions has all the necessary ingredients for successful baryogenesis, although these … 查看更多內容 Published articles • Frampton, P.
