Using the non-equilibrium Keldysh Green's function formalism, we investigate the local, non-equilibrium charge transport in graphene nanoribbons (GNRs). In particular, we demonstrate that the spatial current patterns associated with discrete transmis

Abstract Magnet-superconductor hybrid (MSH) systems represent promising platforms to host Majorana zero modes (MZMs), the elemental building blocks for fault-tolerant quantum computers. Theoretical description of such MSH structures is mostly based o

The problem of manipulating quantum phenomena, such as quantum phase transitions, has a longstanding history in condensed matter research. This paper studies the non-equilibrium emergence and manipulation of Yu-Shiba-Rusinov states in response to ext

Topological superconductors are expected to play an important role in the development of quantum computing devices and iron-based superconductors represent an ideal platform to explore and engineer the underlying physics. Here, the authors investigat

Abstract Atomic manipulation and interface engineering techniques have provided an intriguing approach to custom-designing topological superconductors and the ensuing Majorana zero modes, representing a paradigm for the realization of topological qua

The mechanism underlying screening of a Kondo lattice of magnetic moments by conduction electrons is an important unsolved problem. Figgins et al. use STM techniques to assemble nanoscale Kondo droplets that extrapolate between a single moment and th

The mechanism of collective magnetic excitations in unconventional superconductors remains controversial. Here, Song et al. show neutron spin resonance in a heavy fermion superconductor Ce1-xYbxCoIn5, implying magnon-like excitation rather than spin-

Magnet-superconductor hybrid (MSH) systems are a key platform for custom-designed topological superconductors. Ideally, the ends of a one-dimensional MSH structure will host Majorana zero-modes (MZMs), the fundamental unit of topological quantum comp
