摘要：Proximity ferroelectricity is an interface-associated phenomenon in electric-field-driven polarization reversal in a non-ferroelectric polar material induced by one or more adjacent ferroelectric materials. Here we report proximity ferroelectricity in wurtzite ferroelectric heterostructures. In the present case, the non-ferroelectric layers are AlN and ZnO, whereas the ferroelectric layers are Al1-xBxN, Al1-xScxN and Zn1-xMgxO. The layered structures include nitride-nitride, oxide-oxide and ni...

摘要：Topological design of pi electrons in zigzag-edged graphene nanoribbons (ZGNRs) leads to a wealth of magnetic quantum phenomena and exotic quantum phases1, 2, 3, 4, 5, 6, 7, 8, 9-10. Symmetric ZGNRs typically show antiferromagnetically coupled spin-ordered edge states1,2. Eliminating cross-edge magnetic coupling in ZGNRs not only enables the realization of a class of ferromagnetic quantum spin chains11, enabling the exploration of quantum spin physics and entanglement of multiple qubits in the...

摘要：Mollusca is the second most species-rich animal phylum, but the pathways of early molluscan evolution have long been controversial1, 2, 3, 4-5. Modern faunas retain only a fraction of the past forms in this hyperdiverse and long-lived group. Recent analyses6, 7-8 have consistently recovered a fundamental split into two sister clades, Conchifera (including gastropods, bivalves and cephalopods) and Aculifera9, comprising Polyplacophora ('chitons') and Aplacophora. Molluscan evolution in toto is ...

摘要：The concept of non-Hermiticity has expanded the understanding of band topology, leading to the emergence of counter-intuitive phenomena. An example is the non-Hermitian skin effect (NHSE)1, 2, 3, 4, 5, 6-7, which involves the concentration of eigenstates at the boundary. However, despite the potential insights that can be gained from high-dimensional non-Hermitian quantum systems in areas such as curved space8, 9-10, high-order topological phases11,12 and black holes13,14, the realization of t...

摘要：Anhedonia, the diminished drive to seek, value, and learn about rewards, is a core feature of major depressive disorder1, 2-3. The neural underpinnings of anhedonia and how this emotional state drives behaviour remain unclear. Here we investigated the neural code of anhedonia by taking advantage of the fact that when mice are exposed to traumatic social stress, susceptible animals become socially withdrawn and anhedonic, whereas others remain resilient. By performing high-density electrophysio...

摘要：Motor skill repertoire can be stably retained over long periods, but the neural mechanism that underlies stable memory storage remains poorly understood1-8. Moreover, it is unknown how existing motor memories are maintained as new motor skills are continuously acquired. Here we tracked neural representation of learned actions throughout a significant portion of the lifespan of a mouse and show that learned actions are stably retained in combination with context, which protects existing memorie...
