Tunable decoupling of coexisting magnetic orders in Co$_1/3$TaS$_2$

Posted by klaurent Caltech

Kavli Affiliate: Linda Ye| Summary:In multiferroics, new physical responses and functionalities emerge when symmetry-distinct order parameters couple. This conventionally occurs when lattice and magnetic degrees of freedom order independently in a material. Here, we report an all-magnetic analogue of multiferroic behavior in the antiferromagnet Co$_1/3$TaS$_2$, where topological scalar spin chirality and nematicity coexist on the […]

Merger-driven buildup of the $M_rm BH$ – $M_*$ relation bridging high-$z$ overmassive black holes with the local relation

Posted by klaurent Tokyo

Kavli Affiliate: John Silverman | Summary:The origin of the mass scaling relation between supermassive black holes (SMBHs, $M_rm BH$) and galaxies ($M_*$) remains a key open question. Rather than invoking AGN feedback, a non-causal mechanism has been proposed in which multiple mergers average out the $M_rm BH/M_*$ ratio, thus decreasing its scatter ($σ$) and forming […]

Saxiphilin is a broad-spectrum toxin sponge for C13-modified saxitoxins

Posted by dbos UCSF

Kavli Affiliate: Daniel Minor | Authors: Sandra Zakrzewska, Zhou Chen, Elizabeth Park, Roshni G Bhaskar, T. Aaron Bedell, J Du Bois and Daniel L Minor, Jr. | Summary: Saxitoxin (STX) and its congeners (paralytic shellfish toxins, PSTs) are among the most potent small-molecule toxins. PSTs are produced by harmful algal blooms and derive toxicity by […]

Cell-type-specific sustained value representations in the claustrum

Posted by dbos Hopkins

Kavli Affiliate: Solange Brown and Jeremiah Cohen | Authors: Ahmad B. Taha, Seong Yeol An, Su-Jeong Kim, Rowhan Daly, Jeremiah Y. Cohen and Solange P. Brown | Summary: Flexible decision-making relies on interactions between frontal cortex and subcortical structures. The claustrum, a subcortical nucleus highly interconnected with frontal cortex, influences cortical activity and has been […]

Pattern stability in reaction-diffusion systems depends on path entropy

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | Summary:Reaction-diffusion systems driven far from thermodynamic equilibrium through the injection of energy can support multiple distinct spatial patterns that persist as long-lived dynamical phases. The stability of these metastable phases is not determined by thermodynamics, but by the transition paths connecting them. At finite particle numbers, intrinsic stochasticity induces […]
