Picosecond volume expansion drives a later-time insulator-metal transition in a nano-textured Mott Insulator

Posted by klaurent April 4, 2023Cornell

Kavli Affiliate: Nicole A. Benedek | Summary:Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrinsic timescales of electrons (femtoseconds) and associated phonons (10s of femtoseconds to few picoseconds), which is possible with short-pulse photoexcitation. Yet, in many Mott insulators, the electronic […]

Predictive Sequence Learning in the Hippocampal Formation

Posted by klaurent April 4, 2023April 17, 2023UCSD / Salk

Kavli Affiliate: Terrence Sejnowski | Authors: Yusi Chen, Huanqiu Zhang and Terrence J Sejnowski | Summary: We linked the temporal precision of neural encoding to the implementation of cognitive functions through predictive sequence learning. The hippocampus of rodents receives sequences of sensory inputs from the cortex during exploration and then encodes the sequences with millisecond […]

Simulating Cosmological Evolution by Quantum Quench of an Atomic BEC

Posted by klaurent April 4, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Han Fu, K. Levin, , | Summary: In cosmological evolution, it is the homogeneous scalar field (inflaton) that drives the universe to expand isotropically and to generate standard model particles. However, to simulate cosmology, atomic gas research has focused on the dynamics of Bose-Einstein condensates […]

LHS 475 b: A Venus-sized Planet Orbiting a Nearby M Dwarf

Posted by klaurent April 4, 2023MIT

Kavli Affiliate: Alan Levine | Summary:Based on photometric observations by TESS, we present the discovery of a Venus-sized planet transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is $0.274 pm 0.015~rmM_Sun$. The planet, originally reported as TOI 910.01, has an orbital period of $2.0291025 pm 0.0000020$ […]

Attribute-Consistent Knowledge Graph Representation Learning for Multi-Modal Entity Alignment

Posted by klaurent April 4, 2023Caltech

Kavli Affiliate: Lihong Wang | First 5 Authors: Qian Li, Shu Guo, Yangyifei Luo, Cheng Ji, Lihong Wang | Summary: The multi-modal entity alignment (MMEA) aims to find all equivalent entity pairs between multi-modal knowledge graphs (MMKGs). Rich attributes and neighboring entities are valuable for the alignment task, but existing works ignore contextual gap problems […]

Fabrication of a Monolithic 5-Meter Aluminum Reflector for Millimeter-Wavelength Observations of the Cosmic Microwave Background

Posted by klaurent April 4, 2023Chicago

Kavli Affiliate: Bradford Benson | First 5 Authors: Tyler Natoli, Bradford Benson, John Carlstrom, Eric Chauvin, Bruno Clavel | Summary: We have demonstrated the fabrication of a monolithic, 5-meter diameter, aluminum reflector with 17.4 $mu$m RMS surface error. The reflector was designed to avoid the problem of pickup due to scattering from panel gaps in […]
