Highly efficient visible and near-IR photon pair generation with thin-film lithium niobate

Kavli Affiliate: Alireza Marandi | First 5 Authors: Nathan Harper, Emily Hwang, Ryoto Sekine, Luis Ledezma, Christian Perez | Summary: Efficient on-chip entangled photon pair generation at telecom wavelengths is an integral aspect of emerging quantum optical technologies, particularly for quantum communication and computing. However, moving to shorter wavelengths enables the use of more accessible […]

The look of high-velocity red-giant star collisions

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Luc Dessart, Taeho Ryu, Pau Amaro Seoane, Andrew M. Taylor, | Summary: High-velocity stellar collisions driven by a supermassive black hole (BH) or BH-driven disruptive collisions, in dense, nuclear clusters can rival the energetics of supergiant star explosions following gravitational collapse of their iron core. Here, […]

Modulation Instability and Wavenumber Bandgap Breathers in a Time Layered Phononic Lattice

Kavli Affiliate: Chiara Daraio | First 5 Authors: Christopher Chong, Brian Kim, Evelyn Wallace, Chiara Daraio, | Summary: We demonstrate the existence of wavenumber bandgap (q-gap) breathers in a time-periodic phononic lattice. These breathers are localized in time and periodic in space, and are the counterparts to the classical breathers found in spatially-periodic systems. We […]

The Geometry of Truth: Emergent Linear Structure in Large Language Model Representations of True/False Datasets

Kavli Affiliate: Max Tegmark | First 5 Authors: Samuel Marks, Max Tegmark, , , | Summary: Large Language Models (LLMs) have impressive capabilities, but are prone to outputting falsehoods. Recent work has developed techniques for inferring whether a LLM is telling the truth by training probes on the LLM’s internal activations. However, this line of […]
