Isotropic 3D topological phases with broken time reversal symmetry

Kavli Affiliate: Anton Akhmerov | Summary:Axial vectors, such as current or magnetization, are commonly used order parameters in time-reversal symmetry breaking systems. These vectors also break isotropy in three dimensional systems, lowering the spatial symmetry. We demonstrate that it is possible to construct a three-dimensional medium with average isotropy and inversion symmetry where time-reversal symmetry […]

A Fermi Surface Descriptor Quantifying the Correlations between Anomalous Hall Effect and Fermi Surface Geometry

Kavli Affiliate: Mazhar Ali | Summary: In the last few decades, basic ideas of topology have completely transformed the prediction of quantum transport phenomena. Following this trend, we go deeper into the incorporation of modern mathematics into quantum material science focusing on geometry. Here we investigate the relation between the geometrical type of the Fermi […]

Lack of near-sightedness principle in non-Hermitian systems

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Anton R. Akhmerov, Ion Cosma Fulga, | Summary: The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its […]

Optimality in superselective surface binding by multivalent DNA nanostars

Kavli Affiliate: Jos Zwanikken | Summary:Weak multivalent interactions govern a large variety of biological processes like cell-cell adhesion and virus-host interactions. These systems distinguish sharply between surfaces based on receptor density, known as superselectivity. Earlier experimental and theoretical work provided insights into the control of selectivity: Weak interactions and a high number of ligands facilitate […]

Effects of local incompressibility on the rheology of composite biopolymer networks

Kavli Affiliate: Gijsje Koenderink | Summary:Fibrous networks such as collagen are common in biological systems. Recent theoretical and experimental efforts have shed light on the mechanics of single component networks. Most real biopolymer networks, however, are composites made of elements with different rigidity. For instance, the extracellular matrix in mammalian tissues consists of stiff collagen […]

Supercurrent mediated by helical edge modes in bilayer graphene

Kavli Affiliate: Srijit Goswami | First 5 Authors: Prasanna Rout, Nikos Papadopoulos, Fernando Peñaranda, Kenji Watanabe, Takashi Taniguchi | Summary: Bilayer graphene encapsulated in tungsten diselenide can host a weak topological phase with pairs of helical edge states. The electrical tunability of this phase makes it an ideal platform to investigate unique topological effects at […]
