Anomalous Pressure-Enhanced Polarization in Sliding Ferroelectrics

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:Hydrostatic pressure commonly suppresses polarization in conventional displacive ferroelectrics by weakening the off-center ionic distortion. Sliding ferroelectrics may provide a contrasting case because their polarization arises from stacking-dependent interlayer charge transfer rather than intra-unit-cell ionic displacement. Here, hydrostatic pressure is shown to enhance, rather than suppress, the polarization of parallel-stacked […]

Hunger reconfigures a reward learning circuit into a memory competent mode

Posted by dbos Columbia

Kavli Affiliate: Rui Costa | Authors: Annie Park, Bhagyashree Senapati, Nino Mancini, Youchong Zhang, Juliana Choi, Ian Cone, Christoph D Treiber, Rui Ponte Costa, Lisa M Fenk, Salil Sanjay Bidaye and Scott Waddell | Summary: Internal states such as hunger dynamically reshape activity across circuits to support resource seeking. Neuromodulation provides a means of controlling […]

Instrumental-Motor Transfer: The Relative Value of Competing Movement Goals Modulates Implicit Motor Learning

Posted by dbos Hopkins

Kavli Affiliate: Vikram Chib | Authors: Naser Al-Fawakhiri, Vikram S. Chib and Samuel D. McDougle | Summary: Motor learning depends on the integration of several, often competing signals, including reward and punishment (which guide learning the value of actions via reinforcement learning) and sensorimotor errors (which refine the execution of actions via motor adaptation). If […]

SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | Summary:We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at $z=3.34$ behind the galaxy cluster RXC J0018.5+1626. The transient was identified as a red F150W-dropout source (F277W = 26.1 mag) in JWST/NIRCam imaging taken on 2026 July 3 for the […]

Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | Summary:Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the interstellar medium. Disentangling these components remains a challenge, as most spectral tracers are affected by both processes, limiting robust interpretation of kinematics and […]

Molecular Beam Epitaxy of AgTaO3

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | Summary:We report the first synthesis of single-crystal AgTaO3 thin films using molecular-beam epitaxy (MBE). High-quality epitaxial AgTaO3 films were grown on both (001)- and (111)-oriented SrTiO3 substrates using sequential deposition of atomic silver and TaO2 layers under an ozone/oxygen atmosphere (80 % O3 + 20 % O2). X-ray diffrac- tion […]
