Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes

Advanced Functional Materials, EarlyView.
This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for

Graviton reggeization and high energy gravitational scattering of scalar particles

European Physical Journal C: Particles and Fields
In this paper we consider a high energy scattering of free scalar particles through a gravitational field. The one particle t-channel amplitude of the scattering in this limit is governed by reggeized graviton.

The interplay of hadronic amplitudes and Coulomb phase in LHC measurements at 13 TeV

Physics Letters B, 2019
Detailed analysis of the measurements of differential cross sections in the forward region of pp elastic scattering at 13 TeV in LHC is performed. The structures of the real and imaginary parts of the scattering amplitude are investigated, both requiring

Y‐system for scattering amplitudes [PDF]

Fortschritte der Physik, 2011
AbstractWe review recent progress on computing scattering amplitudes of planar 𝒩 = 4 super Yang‐Mills at strong coupling by using the AdS/CFT duality. The problem boils down to the computation of certain minimal areas on AdS. We show how to use the integrability of the classical equations of motion in order to efficiently compute such minimal areas.

Curved Nanographene–Graphite Hybrid Anodes with Sequential Li+ Insertion for Fast‐Charging and Long‐Life Li‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hybrid anode composed of Cl‐functionalized curved nanographene and graphite enables ultra‐fast charging and long cycle life through an engineered morphology and sequential Li+ insertion. It delivers 100 mAh g−1 at 5 C with 70% capacity retention after 1000 cycles and maintains stable performance over 2000 cycles in pouch cells, providing a practical ...

Cwebs in multiparton scattering amplitude: Structures at four loops [PDF]

EPJ Web of Conferences
Soft function exponentiates in terms of the soft anomalous dimension ΓS; the Feynman diagrams contributing to it are called Cwebs. The colour and kinematics of a Cweb mix via a web mixing matrix – calculation of web mixing matrices at higher loop orders ...

Interatomic collisions in two-dimensional and quasi-two-dimensional confinements with spin-orbit coupling

, 2012
We investigate the low-energy scattering and bound states of two two-component fermionic atoms in pure two-dimensional (2D) and quasi-2D confinements with Rashba spin-orbit coupling (SOC). We find that the SOC qualitatively changes the behavior of the 2D

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami

Advanced Functional Materials, EarlyView.
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.
