Constraints on axion-like polarization oscillations in the cosmic microwave background with POLARBEAR

Posted by klaurent Tokyo

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: The POLARBEAR Collaboration, Shunsuke Adachi, Tylor Adkins, Kam Arnold, Carlo Baccigalupi | Summary: Very light pseudoscalar fields, often referred to as axions, are compelling dark matter candidates and can potentially be detected through their coupling to the electromagnetic field. Recently a novel detection technique using the cosmic […]

Defeating Broken Symmetry with Doping: Symmetric Resonant Tunneling in Noncentrosymetric Heterostructures

Posted by dbos Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Jimy Encomendero, Vladimir Protasenko, Debdeep Jena, Huili Grace Xing, | Summary: Resonant tunneling transport in polar heterostructures is intimately connected to the polarization fields emerging from the geometric Berry-phase. In these structures, quantum confinement results not only in a discrete electronic spectrum, but also in built-in polarization […]

Organization and Plasticity of Inhibition in Hippocampal Recurrent Circuits

Posted by klaurent Columbia

Kavli Affiliate: Attila Losonczy | Authors: Bert Vancura, Tristan Geiller and Attila Losonczy | Summary: Excitatory-inhibitory interactions structure recurrent network dynamics for efficient cortical computations. In the CA3 area of the hippocampus, recurrent circuit dynamics, including experience-induced plasticity at excitatory synapses, are thought to play a key role in episodic memory encoding and consolidation via […]
