Advanced Functional Materials, EarlyView.Two‐dimensional electronic states are the foundation of modern semiconductor technology. Here, we report molecular‐beam epitaxy growth of fractional double perovskite, EuTa2O6. Reciprocal space mapping and transmission electron microscopy confirm a layered ordering of A‐site cations.

Fermionic Chern-Simons Theory of SU(4) Fractional Quantum Hall Effect
, 2011 We develop a Fermionic Chern-Simons (CS) theory for the fractional quantum Hall effect in monolayer graphene with SU(4) symmetry, arising from the spin and the valley degrees of freedom, which involves four distinct CS gauge fields.

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases
Advanced Materials, EarlyView.The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Few-body, hyperspherical treatment of the quantum Hall effect
EPJ Web of Conferences, 2016 The quantum Hall effect arises from the quantum behavior of two-dimensional, strongly-interacting electrons exposed to a strong, perpendicular magnetic field [1, 2].

Non-Hermitian skin clusters from strong interactions
Communications Physics, 2022 This study extends the notion of the non-Hermitian skin effect to the regime where many-body interactions dominate single particle energetics, reminiscent of fractional quantum Hall systems.

Theory of Incompressible States in a Narrow Channel
, 1997 We report on the properties of a system of interacting electrons in a narrow channel in the quantum Hall effect regime. It is shown that an increase in the strength of the Coulomb interaction causes abrupt changes in the width of the charge-density ...

A holographic model for the fractional quantum Hall effect [PDF]
Journal of High Energy Physics, 2015 Experimental data for fractional quantum Hall systems can to a large extent be explained by assuming the existence of a modular symmetry group commuting with the renormalization group flow and hence mapping different phases of two-dimensional electron gases into each other.

Advanced Materials, EarlyView.Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

Poissonian tunneling through an extended impurity in the quantum Hall effect
, 2010 We consider transport in the Poissonian regime between edge states in the quantum Hall effect. The backscattering potential is assumed to be arbitrary, as it allows for multiple tunneling paths.

Numerical investigation of gapped edge states in fractional quantum Hall-superconductor heterostructures [PDF]
, 2018 Fractional quantum Hall-superconductor heterostructures may provide a platform towards non-abelian topological modes beyond Majoranas. However their quantitative theoretical study remains extremely challenging.
