Thermodynamic Discovery of Tetracriticality and Emergent Multicomponent Superconductivity in UTe$_2$

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:The candidate topological superconductor UTe$_2$ exhibits a complex phase diagram with multiple superconducting states, yet the nature of their coexistence has remained a central mystery. In particular, the apparent intersection of two second-order phase boundaries at a “triple point” in the pressure-temperature phase diagram is thermodynamically forbidden, suggesting hidden phase […]

Complementary RL: Towards Efficient Experience-Driven Agent Learning

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Reinforcement Learning (RL) has emerged as a powerful paradigm for training LLM-based agents, yet remains limited by low sample efficiency, stemming not only from sparse outcome feedback but also from the agent’s inability to leverage prior experience across episodes. While augmenting agents with historical experience offers a promising remedy, existing approaches […]

Thermodynamic accessibility of Li-Mn-Ti-O cation disordered rock-salt phases

Posted by klaurent Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:Disordered rock-salt with Li-excess (DRX) cathode phases within the Li-Mn-Ti-O (LMTO) composition space have recently been extensively studied, as they promise to deliver exceptional energy density at low cost in Li-ion batteries. The continued development of LMTO DRX with improved power density and cycling stability requires optimization of the composition and […]

Difference-Based High-Dimensional Long-Run Covariance Matrix Estimation for Mean-shift Time Series

Posted by klaurent Peking

Kavli Affiliate: Feng Long| Summary: We consider estimation of high-dimensional long-run covariance matrices for time series with nonconstant means, a setting in which conventional estimators can be severely biased. To address this difficulty, we propose a difference-based initial estimator that is robust to a broad class of mean variations, and combine it with hard thresholding, […]

SLSim: a strong lensing population simulation package

Posted by klaurent Chicago

Kavli Affiliate: Richard Kessler | Summary:Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multiple images of distant sources, crucial for precise cosmological measurements and understanding the distribution of dark matter in the universe. Current studies are limited by the number of […]
