Topological finite size effect in one-dimensional chiral symmetric systems

Posted by dbos Delft

Kavli Affiliate: Eliska Greplova | First 5 Authors: Guliuxin Jin, D. O. Oriekhov, Lukas Johannes Splitthoff, Eliska Greplova, | Summary: Topological phases of matter have been widely studied for their robustness against impurities and disorder. The broad applicability of topological materials relies on the reliable transition from idealized, mathematically perfect models to finite, real-world implementations. […]

Charge-induced energy shift of a single-spin qubit under a magnetic-field gradient

Posted by dbos Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Takashi Kobayashi, Akito Noiri, Takashi Nakajima, Kenta Takeda, Leon C. Camenzind | Summary: An electron confined by a semiconductor quantum dot (QD) can be displaced by changes in electron occupations of surrounding QDs owing to the Coulomb interaction. For a single-spin qubit in an inhomogeneous magnetic field, […]
