Antiferromagnetic Ground State, Charge Density Waves and Oxygen Vacancies Induced Metal-Insulator Transition in Pressurized La$_{3}$Ni$_{2}$O$_{7}$

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xin-Wei Yi, Ying Meng, Jia-Wen Li, Zheng-Wei Liao, Jing-Yang You | Summary: La$_{3}$Ni$_{2}$O$_{7}$ has garnered widespread interest recently due to its high-temperature superconductivity under pressure, accompanied by charge density wave (CDW) ordering and metal-insulator (MI) transitions in the phase diagram. Here, we reveal with comprehensive calculations that […]

Representing the dynamics of natural marmoset vocal behaviors in frontal cortex

Posted by dbos UCSD / Salk

Kavli Affiliate: Cory Miller | Authors: Jingwen Li, Mikio Christian Aoi and Cory Miller | Summary: Here we tested the respective contributions of primate premotor and prefrontal cortex to support vocal behavior. We applied a model-based GLM analysis that better accounts for the inherent variance in natural, continuous behaviors to characterize the activity of neurons […]

Tell machine learning potentials what they are needed for: Simulation-oriented training exemplified for glycine

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Fuchun Ge, Ran Wang, Chen Qu, Peikun Zheng, Apurba Nandi | Summary: Machine learning potentials (MLPs) are widely applied as an efficient alternative way to represent potential energy surfaces (PES) in many chemical simulations. The MLPs are often evaluated with the root-mean-square errors on the test set […]

Subvolume method for SU(2) Yang-Mills theory at finite temperature: topological charge distributions

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Norikazu Yamada, Masahito Yamazaki, Ryuichiro Kitano, , | Summary: We apply the previously-developed sub-volume method to study the $theta$-dependence of the four-dimensional SU(2) Yang-Mills theory at finite temperature. We calculate the first two coefficients, the topological susceptibility $chi$ and the fourth cumulant $b_2$, in the $theta$-expansion of […]

Sparse-Coding Variational Auto-Encoders

Posted by dbos Hopkins

Kavli Affiliate: Adam S. Charles | Authors: Victor Geadah, G. Barello, Adam Charles and Jonathan Pillow | Summary: The sparse coding model posits that the visual system has evolved to efficiently code natural stimuli using a sparse set of features from an overcomplete dictionary. The original sparse coding model suffered from two key limitations, however: […]
