Abstract:Here we show that domain walls in minimally twisted bilayer graphene support exceptionally robust proximity superconductivity in the quantum Hall regime, allowing Josephson junctions to operate in fields close to the upper critical field of superconducting electrodes. The critical current is found to be non-oscillatory and practically unchanging over the entire range of quantizing fields, with its value being limited by the quantum conductance of ballistic, strictly one-dimensional, electronic channels residing within the domain walls. The system described is unique in its ability to support Andreev bound states at quantizing fields and offers many interesting directions for further exploration.

Ferroelectric materials are attractive because they provide a way to change electrical resistance by using an electric field. Lee et al. used simulations to explain the persistence of ferroelectric behavior in very thin films of hafnium oxide. The authors' calculations show that ferroelectric properties should be found in films below 1 nanometer thick. This makes the material very attractive for the next generation of random access memory.

新邦德可能是“非二元性别”?国外网民哀嚎:007要完蛋了
据美国福克斯新闻网当地时间12月11日报道,007制片人芭芭拉·布洛柯里日前透露,最早明年开始寻找新的“詹姆斯·邦德”人选,继任者希望是英国人,可能不是白人,但不会是女性,且不排除邦德未来被设定为“非二元性别”的可能性,即角色自我认同既非男性又非女性。
