Squeezed states of light in micromaser

open access: yesMoldavian Journal of the Physical Sciences, 2006
We study a lossless micromaser with atomic polarization. It is shown that for certain values of time of the atomic flight through the cavity, the field evolves to a pure state. The squeezing properties of the cavity field are examined.

Cluster‐Mediated Solute Stabilization and Shear‐Bypass Synergistic Strengthening in High‐Alloyed Systems

open access: yesAdvanced Science, EarlyView.
This study demonstrates that in high‐alloy systems, nanoclusters with high solute tolerance can effectively suppress compositional segregation. This mitigation leads to a concurrent 18.7% increase in strength and 41.5% improvement in ductility, which is attributed to a shear‐bypass synergistic strengthening mechanism. The findings provide a new pathway

Magnon squeezing via reservoir-engineered optomagnomechanics

open access: yesAPL Photonics
We show how to prepare magnonic squeezed states in an optomagnomechanical system in which magnetostriction induced mechanical displacement couples to an optical cavity via radiation pressure.

Magneto‐X Effects in Magnetic Soft Materials and Their Applications

open access: yesAdvanced Science, EarlyView.
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

open access: yesAdvanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

Targeted Thrombolysis via CCR2‐Engineered Macrophage‐Mimicking Microbubbles Safely Ablates Venous, Arterial, and Microvascular Thrombosis

open access: yesAdvanced Science, EarlyView.
CCR2‐Enhanced Macrophage Membrane–Camouflaged Microbubbles for MCP‐1–Mediated Thrombus Targeting and Ultrasound‐Triggered Urokinase Release. ABSTRACT The clinical management of thrombosis, a primary cause of death worldwide, is hampered by the limitations of current thrombolytic agents, including short half‐life and high risk of off‐target bleeding ...

Quantum phase transitions in driven Fock-state lattices with synthetic gauge fields

open access: yesPhysical Review Research
Quantum phase transitions (QPTs) typically emerge in the thermodynamic limit, yet a single-atom QPT can arise when it is coupled to a coherently driven cavity, which provides a simple and unique platform to engineer quantum states with quantum ...

High‐Order Nonlinear Photonic Crystal with Ordered Structures for Giant Enhancement of Frequency Tripling

open access: yesAdvanced Science, EarlyView.
A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...
