Local Convertibility and Edge States in Quantum Many Body Systems
Local Convertibility Edge States Quantum Many Body Systems
2016/1/22
In some many-body systems, certain ground-state entanglement (Rényi) entropies increase even as the correlation length decreases. This entanglement nonmonotonicity is a potential indicator of nonclass...
Edge states and topological phases in non-Hermitian systems
Edge states topological phases non-Hermitian systems Mesoscale and Nanoscale Physics

Abstract: Topological stability of the edge states is investigated for non-Hermitian systems. We examine two classes of non-Hermitian Hamiltonians supporting real bulk eigenenergies in weak non-Hermit...
Surface density of states and topological edge states in non-centrosymmetric superconductors
Surface density of states topological edge states non-centrosymmetric superconductors

We study Andreev bound state (ABS) and surface density of state (SDOS) of non-centrosymmetric
superconductor where spin-singlet d-wave pairing mixes with spin-triplet p (or f)-wave one by spinorbit c...
Full electrical control of Charge and Spin conductance through Interferometry of Edge States in Topological Insulators
Full electrical control of Charge Spin conductance Topological Insulators

We investigate electron interferometry of edge states in Topological Insulators. We show that,
when inter-boundary coupling is induced at two quantum point contacts of a four terminal setup,
both Fa...
Edge states in two-dimensional electron gas with heterogeneous spin-orbit interaction
Edge states two-dimensional electron gas heterogeneous spin-orbit interaction
2010/11/23
We show that edge states similar to those known for topological insulators exist in two-dimensional electron system with one-band spectrum in the presence of heterogeneous spin-orbit interaction (SOI)...
Edge states in graphene quantum dots: Fractional quantum Hall effect analogies and differences at zero magnetic field
Edge states graphene quantum dots Fractional quantum Hall zero magnetic field

We investigate the way that the degenerate manifold of midgap edge states in quasicircular graphene quantum dots with zig-zag boundaries supports, under free-magnetic-field conditions, strongly correl...
