The Interplay Between Electron Localization, Magnetic Order, and Jahn-Teller Distortion that Dictates LiMnO$_2$ Phase Stability

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ronald L. Kam, Luca Binci, Aaron D. Kaplan, Kristin A. Persson, Nicola Marzari | Summary: The development of Mn-rich cathodes for Li-ion batteries promises to alleviate supply chain bottlenecks in battery manufacturing. Challenges in Mn-rich cathodes arise from Jahn-Teller (JT) distortions of Mn$^{3+}$, Mn migration, and […]

A spatial model of autophosphorylation of Ca2+/calmodulin-dependent protein kinase II (CaMKII) predicts that the lifetime of phospho-CaMKII after induction of synaptic plasticity is greatly prolonged by CaM-trapping.

Kavli Affiliate: Terrence Sejnowski | Authors: Thomas M Bartol, Mariam Ordyan, Terrence J Sejnowski, Padmini Rangamani and Mary B Kennedy | Summary: Long-term potentiation (LTP) is a biochemical process that underlies learning in excitatory glutamatergic synapses in the Central Nervous System (CNS). The critical early driver of LTP is autophosphorylation of the abundant postsynaptic enzyme, […]

Functional organization and natural scene responses across mouse visual cortical areas revealed with encoding manifolds – Copy

Posted by dbos Rockefeller, This Week: Neuroscience

Kavli Affiliate: Roderick MacKinnon | Authors: Venkata Shiva Mandala and Roderick MacKinnon | Summary: Gating in voltage-dependent ion channels is regulated by the transmembrane voltage. This form of regulation is enabled by voltage sensing domains (VSDs) that respond to transmembrane voltage differences by changing their conformation and exerting force on the pore to open or […]

Functional organization and natural scene responses across mouse visual cortical areas revealed with encoding manifolds

Posted by dbos This Week: Neuroscience, UCSF

Kavli Affiliate: Michael Stryker | Authors: Luciano Dyballa, Greg D Field, Michael P Stryker and Steven W Zucker | Summary: A challenge in sensory neuroscience is understanding how populations of neurons operate in concert to represent diverse stimuli. To meet this challenge, we have created “encoding manifolds” that reveal the overall responses of brain areas […]

A Versatile Chip-Scale Platform for High-Rate Entanglement Generation using an AlGaAs Microresonator Array

Posted by dbos This Week: Theoretical Physics, UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Yiming Pang, Joshua E. Castro, Trevor J. Steiner, Liao Duan, Noemi Tagliavacche | Summary: Integrated photonic microresonators have become an essential resource for generating photonic qubits for quantum information processing, entanglement distribution and networking, and quantum communications. The pair generation rate is enhanced by reducing the […]

Kramers-protected hardware-efficient error correction with Andreev spin qubits

Posted by dbos Delft, This Week: Nanoscience

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Haoran Lu, Isidora Araya Day, Anton R. Akhmerov, Bernard van Heck, Valla Fatemi | Summary: We propose an architecture for bit flip error correction of Andreev spins that is protected by Kramers’ degeneracy. Specifically, we show that a coupling network of linear inductors results in a […]

Not all cross-modal responses are explained by face movements

Posted by dbos This Week: Neuroscience, UCSF

Kavli Affiliate: Andrea Hasenstaub | Authors: Timothy R Olsen and Andrea R Hasenstaub | Summary: Recent work has claimed that most apparently cross-modal responses in sensory cortex are instead caused by the face movements evoked by stimuli of the non-dominant modality. We show that visual stimuli rarely trigger face movements in awake mice; when they […]
