Small curvature laminations in hyperbolic 3–manifolds [PDF]

Algebraic & Geometric Topology, 2009
We show that if $\mathcal{L}$ is a codimension-one lamination in a finite volume hyperbolic 3-manifold such that the principal curvatures of each leaf of $\mathcal{L}$ are all in the interval $(- , )$ for a fixed $ \in[0,1)$ and no complimentary region of $\mathcal{L}$ is an interval bundle over a surface, then each boundary leaf of $\mathcal{L ...

The genus spectrum of a hyperbolic 3-manifold [PDF]

, 2009
In this article we study the spectrum of totally geodesic surfaces of a finite volume hyperbolic 3-manifold. We show that for arithmetic hyperbolic 3-manifolds that contain a totally geodesic surface, this spectrum determines the commensurability class ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Controlled Movement of Soft Actuators using Multi‐Responsive Microgel Arrays and Microcirculatory Systems

Advanced Functional Materials, EarlyView.
Microscale hydrogels (microgels) feature improved mass transport characteristics supportive of fast actuation and chemical tunability amenable to programmed stimuli response. A unique soft actuator architecture is realized by encapsulating microgels in soft microcirculatory systems which enable the convenient delivery of liquid stimuli for powering and

Two-dimensional SCFTs from matter-coupled $$7D~N=2$$ 7DN=2 gauged supergravity

European Physical Journal C: Particles and Fields, 2019
We study supersymmetric $$AdS_3\times M^4$$ AdS3×M4 solutions of $$N=2$$ N=2 gauged supergravity in seven dimensions coupled to three vector multiplets with $$SO(4)\sim SO(3)\times SO(3)$$ SO(4)∼SO(3)×SO(3) gauge group and $$M^4$$ M4 being a four ...

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives

Advanced Functional Materials, EarlyView.
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

Cone-manifolds and the density conjecture [PDF]

, 2002
We give an expository account of our proof that each cusp-free hyperbolic 3-manifold M with finitely generated fundamental group and incompressible ends is an algebraic limit of geometrically finite hyperbolic 3-manifolds.Comment: 19 Pages, 2 figures; to

Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors

Advanced Materials, EarlyView.
A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Discontinuity in RG flows across dimensions: entanglement, anomaly coefficients and geometry

Journal of High Energy Physics
We study the entanglement entropy associated with a holographic RG flow from AdS7 to AdS4 × ℍ 3, where ℍ 3 is a 3-dimensional hyperbolic manifold with curvature κ. The dual six-dimensional RG flow is disconnected from Lorentz-invariant flows.
