Optics-microwave entanglement and state teleportation mediated by a cavity magnomechanical system

Posted by klaurent Delft

Kavli Affiliate: Ya Blanter | Summary:Generating usable output-entanglement in continuous variable systems can serve as a viable resource for improving applications in quantum information science. In this work, we show how to generate steady-state output-entanglement in a two-stage conversion setup between optical and microwave photon which employs resonantly coupled magnetic and mechanical excitations, as proposed […]

Essentially singular limits of Jacobi operators and applications to higher-order squeezing

Posted by klaurent Berkeley

Kavli Affiliate: Felix Fischer | Summary:We study a family of Jacobi operators in which the diagonal entries are multiplied by a coupling parameter $λgeq0$. Under suitable conditions, the operator is self-adjoint for every $λ>0$, while the formal limit at $λ=0$ is a symmetric Jacobi operator admitting a one-parameter family of self-adjoint extensions. A central ingredient […]

Stacking-order-dependent electronic properties of MoTe2/WSe2 moiré bilayers

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive to the interlayer stacking order. Polarization-resolved optical second harmonic generation (SHG) is the most used technique for stacking order characterization but unverified for most heterobilayers. […]

AI for Auto-Research: Roadmap & User Guide

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:AI-assisted research is crossing a threshold: fully automated systems can now generate research papers for as little as $15, while long-horizon agents can execute experiments, draft manuscripts, and simulate critique with minimal human input. Yet this productivity frontier exposes a deeper integrity problem: under scientific pressure, even frontier LLMs still fabricate […]

Lever: Speculative LLM Inference on Smartphones

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Large language models (LLMs) are increasingly needed for interactive mobile applications, but high-quality models exceed the limited DRAM available on smartphones. Flash storage can hold larger models, yet flash-backed inference is slow because autoregressive decoding repeatedly invokes the target model and incurs costly I/O. We observe that speculative decoding is a […]

CoCo-InEKF: State Estimation with Learned Contact Covariances in Dynamic, Contact-Rich Scenarios

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Robust state estimation for highly dynamic motion of legged robots remains challenging, especially in dynamic, contact-rich scenarios. Traditional approaches often rely on binary contact states that fail to capture the nuances of partial contact or directional slippage. This paper presents CoCo-InEKF, a differentiable invariant extended Kalman filter that utilizes continuous […]

A Qutrit Time Crystal Stabilized with Native Chiral Interactions

Posted by klaurent Berkeley

Kavli Affiliate: Joel Moore | Summary:Periodically driven quantum many-body systems can spontaneously break discrete time-translation symmetry, realizing discrete time crystals. To date, both experimental and theoretical efforts have largely focused on the simplest case of spontaneous period-doubling in $mathbbZ_2$ discrete time crystals realized with qubits. This owes, in part, to the challenge of stabilizing eigenstate […]

Imaging Interacting Two-Dimensional Anisotropic Electrons

Posted by klaurent Berkeley

Kavli Affiliate: Michael Crommie | Summary:We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with anisotropic effective mass, an electron’s quantum wavefunction becomes elongated along the light-mass direction to reduce kinetic energy. At low electron density, such anisotropic electrons are predicted to […]

On-demand steering of hyperbolic chiral polaritons

Posted by klaurent Berkeley

Kavli Affiliate: James Analytis| Summary:Control of light polarization and propagation in sub-wavelength architectures is foundational to nanophotonic technologies. A frontier direction is to leverage strong optical spin-orbit interactions to realize polarization-selective light steering, known as the photonic spin Hall effect. In this context, hyperbolic plasmon polaritons (HPPs) are of particular interest as they offer large […]
