Angled decompositions of arborescent link complements
, 2006 This paper describes a way to subdivide a 3-manifold into angled blocks, namely polyhedral pieces that need not be simply connected. When the individual blocks carry dihedral angles that fit together in a consistent fashion, we prove that a manifold ...

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy
Advanced Optical Materials, EarlyView.Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Generalized Heterodyne Interferometry in Kerr Materials
Advanced Photonics Research, EarlyView.Interferometry, combined with heterodyne detection, enables simultaneous measurement of light amplitude and phase. This work applies these methods to study nonlinear phase shifts from the optical Kerr effect during laser pulse propagation. Results show the nonlinear index is straightforward to retrieve at low phases, but at higher powers, pulse shape ...

A note on background independence in AdS3 string theory
Journal of High Energy PhysicsIn this note, we comment on the path integral formulation of string theory on M $$ \mathcal{M} $$ × S3 × T 4 $$ {\mathbbm{T}}^4 $$ where M $$ \mathcal{M} $$ is any hyperbolic 3-manifold.

Transformer Encoder–Decoder Framework for Nonlinear Pulse Evolution and Inverse Modeling
Advanced Photonics Research, EarlyView.Modeling nonlinear pulse evolution in optical systems is key to advancing photonic technologies. A transformer‐based encoder‐decoder framework is proposed for both forward and inverse modeling, applied to supercontinuum generation. This approach captures complex dynamics efficiently, outperforming traditional methods in speed.

Advanced Robotics Research, EarlyView.Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

3d gravity from Virasoro TQFT: Holography, wormholes and knots
SciPost PhysicsWe further develop the description of three-dimensional quantum gravity with negative cosmological constant in terms of Virasoro TQFT formulated in our previous paper [SciPost Phys. 15, 151 (2023)].
