Semaphorin 3A promotes resilience of sleep and cognition to brain injury

Posted by dbos This Week: Neuroscience, UCSF

Kavli Affiliate: Jeanne Paz | Authors: Deanna Necula, Yuliya Voskobiynyk, Srujana Poluri and Jeanne T. Paz | Summary: Chronic sleep disruption and cognitive deficits are debilitating long-term consequences of traumatic brain injury (TBI), yet the endogenous mechanisms that drive network-level recovery remain poorly understood. Here, we demonstrate that during the chronic phase post-injury, network oscillations […]

Changes in perceptual sampling contribute to representational drift

Posted by dbos This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: John Serences | Authors: Yixin Yuan, John Serences and Mikio Christian Aoi | Summary: Gradual changes in neural response patterns to the same stimulus over time, termed representational drift, have been widely observed across cortical areas. Drift is typically attributed to intrinsic neural dynamics driven by synaptic plasticity or turnover. Here we test […]

Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of $β$-Li$_2$IrO$_3$

Posted by klaurent Berkeley

Kavli Affiliate: James Analytis| Summary:We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material $β$-Li$_2$IrO$_3$, using magnetotropic susceptibility to resolve its low-temperature field-angle phase diagram across the principal crystallographic planes in magnetic fields up to $60$ T. Rather than evolving directly from the low-field incommensurate state into a polarized regime, the system exhibits a […]

Many-body quantum optics in a cascaded chiral network

Posted by klaurent Caltech

Kavli Affiliate: Mohammad Mirhosseini | Summary:Chiral quantum emitters interact with light only in one propagation direction, allowing them to be linked into cascaded systems in which photons mediate ordered, long-range interactions. Such systems are predicted to host novel regimes of many-body physics of light and matter. Exploring these regimes requires arrays of identical quantum emitters […]
