Cryogenic piezoelectric effects in thin film strontium titanate devices

Kavli Affiliate: Oskar Painter | Summary:Next generation quantum technologies will need to rely on efficient transduction between electrical, optical, and mechanical quantum degrees of freedom to generate large-scale entanglement over large distances. The performance of such transducers is fundamentally limited by the cryogenic properties of the underlying materials. Here, we demonstrate that engineering strain in […]

Under Pressure: UV Emission Line Ratios as Barometers of AGN Feedback Mechanisms

Kavli Affiliate: Hsiaowen Chen |Summary:Feedback from active galactic nuclei (AGN) is widely acknowledged to regulate the growth of massive galaxies, though its driving mechanisms are debated. Prevailing theories suggest that AGN-driven outflows are driven either by radiation pressure acting directly on the dusty interstellar medium (ISM) or by hot winds entraining cooler ISM gas, but […]

Integrated Photonic Polarization Synthesizer and Analyzer

Kavli Affiliate: David W. Miller | Summary:Polarization-resolved control and measurement of the optical field are essential for a wide range of photonic systems, including coherent communication, polarimetric sensing, and quantum information processing. We present a photonic integrated circuit that enables the generation and analysis of arbitrary polarization states. The device provides reconfigurable access to the […]

Age-related reconfiguration of locus coeruleus-cortical functional organization

Kavli Affiliate: Maryam Ziaei | Authors: Arjun Dave, Shuer Ye, Xiaqing Lan, Alireza Salami, Heidi Jacobs and Maryam Ziaei | Summary: The locus coeruleus (LC) regulates attention, arousal and adaptive behavior via widespread noradrenergic projections to cortex, yet its large-scale cortical organization and vulnerability to aging remain poorly understood. Using ultra-high-field 7T–MRI during naturalistic viewing […]

Functional connectivity profile of the amygdala subfields associates with emotional well-being in aging

Kavli Affiliate: Maryam Ziaei and Menno Witter | Authors: Shuer Ye, Arjun Dave, Xiaqing Lan, Menno P. Witter, Alireza Salami and Maryam Ziaei | Summary: Amygdala-related functional connectivity plays a crucial role in human emotion, cognition, and mental well-being. The amygdala is a highly heterogeneous structure, with subregions that have both distinct and overlapping functions. […]

X-ray Spectral-Timing Properties of Tidal Disruption Events

Kavli Affiliate: Erin Kara | Summary:We perform the first systematic study of the minute-to-hours-timescale stochastic variability observed in the X-ray luminosity of tidal disruption events (TDEs) using XMM-Newton data and Fourier analysis methods. We measure the spectral properties, power spectral densities (PSDs), fractional variability amplitudes, and energy dependence of the variability for 18 TDEs spanning […]

SimToolReal: An Object-Centric Policy for Zero-Shot Dexterous Tool Manipulation

Kavli Affiliate: Wei Gao| Summary:The ability to manipulate tools significantly expands the set of tasks a robot can perform. Yet, tool manipulation represents a challenging class of dexterity, requiring grasping thin objects, in-hand object rotations, and forceful interactions. Since collecting teleoperation data for these behaviors is challenging, sim-to-real reinforcement learning (RL) is a promising alternative. […]
