Open AccessHorndeski gravity and the violation of reverse isoperimetric inequality
We consider Einstein–Horndeski–Maxwell gravity, together with a cosmological constant and multiple Horndeski axions. We construct charged AdS planar black holes in general dimensions where the Horndeski axions...

Open AccessInvestigation on the phase-transition-induced hysteresis in the thermal transport along the c-axis of MoTe2
The storage and recall of thermal information can be achieved by a thermal memory, which is a key element in the applications of thermal logic devices. Thermal memories can be experimentally realized by solid-...

Acoustic topological insulator and robust one-way sound transport
The acoustic analogue of a topological insulator is shown: a metamaterial exhibiting one-way sound transport along its edge. The system — a graphene-like array of stainless-steel rods — is a promising new plat...

Open AccessHigher-derivative gravity with non-minimally coupled Maxwell field
We construct higher-derivative gravities with a non-minimally coupled Maxwell field. The Lagrangian consists of polynomial invariants built from the Riemann tensor and the Maxwell field strength in such a way ...

Open AccessAn all-optical modulator based on a stereo graphene–microfiber structure
An in-line, all-optical fiber modulator based on a stereo graphene–microfiber structure (GMF) utilizing the lab-on-rod technique was demonstrated in this study. Owing to its unique spring-like geometry, an ult...

Open AccessBlack hole entropy and viscosity bound in Horndeski gravity
Horndeski gravities are theories of gravity coupled to a scalar field, in which the action contains an additional non-minimal quadratic coupling of the scalar, through its first derivative, to the Einstein ten...

Open AccessWavefront sha** of infrared light through a subwavelength hole
Light passing through a subwavelength hole in an opaque plate is a fundamental concern in both optical science and applications. Using both simulations and experiments, we show that, when a subwavelength hole ...
