Broadband, robust, and tunable beam splitter based on topological unidirectional surface magnetoplasmons
Beam splitters are pivotal components in integrated microwave and photonic systems. However, conventional designs based on directional coupling or multi-mode interference often suffer from back scattering, frequency-dependent splitting ratios, and limited bandwidth. To overcome these limitations, here, we propose a new physical mechanism to achieve a broadband, robust, and tunable beam splitter by manipulating the mode coupling of the topological unidirectional surface magnetoplasmons (USMP) at…

Magnetically Responsive Microprintable Soft Nanocomposites with Tunable Nanoparticle Loading
Magnetic remote actuation of soft materials has been demonstrated at the macroscale using hard-magnetic particles for applications such as transforming materials and medical robots. However, due to manufacturing limitations, few microscale magnetically responsive devices exist -- light-based additive manufacturing methods, which are ideal for realizing microscale features, struggle with light scattering induced by the magnetic particles. Moreover, large hard-magnetic microparticles prevent high…

You may have your own thoughts / ideas. Add them to the comments.
I was also torn between the meat grinder and a Plinko metaphor.

How I Evaluate an ACR (VPAT®)
ACRs are Accessibility Conformance Reports, which are the output of a VPAT, or Voluntary Product Accessibility Template maintained by ITIC, or the Information Technology Industry Council (which is why VPAT often has a ® symbol hanging off it). An organization may fill out the template to indicate how or if…

Fast CZ Gate via Energy-Level Engineering in Superconducting Qubits with a Tunable Coupler
In superconducting quantum circuits, decoherence errors in qubits constitute a critical factor limiting quantum gate performance. To mitigate decoherence-induced gate infidelity, rapid implementation of quantum gates is essential. Here we propose a scheme for rapid controlled-Z (CZ) gate implementation through energy-level engineering, which leverages Rabi oscillations between the |11> state and the superposition state in a tunable-coupler architecture. Numerical simulations achieved a 17 …

Conductance Plateaus at Quantum Hall Integer Filling Factors in Germanium Quantum Point Contacts
Constricting transport through a one-dimensional quantum point contact in the quantum Hall regime enables gate-tunable selection of the edge modes propagating between voltage probe electrodes. Here we investigate the quantum Hall effect in a quantum point contact fabricated on low disorder strained germanium quantum wells. For increasing magnetic field, we observe Zeeman spin-split 1D ballistic hole transport evolving to integer quantum Hall states, with well-defined quantised conductance incre…

Amplified Directional Photoluminescence from CIS Quantum Dots and hBN Quantum Emitters using Tunable BIC Metasurfaces
Integrated and tunable light sources are critical for advancing quantum nanophotonic chips in quantum computing, communications, and sensing. However, efficient and tunable emission amplification post-fabrication poses major challenges. Hybrid metasurfaces combining niobium pentoxide (Nb2O5), copper indium sulfide (CIS) quantum dots or hexagonal boron nitride (hBN), and antimony trisulfide (Sb2S3) as a low-loss phase-change material offer a compelling solution for dynamic control and amplificat…

Spectroscopic Determination of Site-Selective Ligand Binding on Single Anisotropic Nanocrystals
Organic surface ligands are integral components of nanocrystals and nanoparticles that have a strong influence on their physicochemical properties, their interaction with the environment, and their ability to self-assemble and order into higher-order structures. These hybrid nanomaterials are tunable with applications in catalysis, directed self-assembly, next-generation optoelectronics, and chemical and quantum sensing. Critically, future advances depend on our ability to rationally engineer t…
