Excitations of quantum Ising chain CoNb2O6 in low transverse field: quantitative description of bound states stabilized by off-diagonal exchange and applied field

Kavli Affiliate: Leon Balents | First 5 Authors: Leonie Woodland, Izabella Lovas, M. Telling, D. Prabhakaran, Leon Balents | Summary: We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNb$_2$O$_6$. High resolution single crystal inelastic neutron scattering measurements observe that small […]

Cross-Modal Representation of Identity in Primate Hippocampus

Kavli Affiliate: Cory Miller | Authors: Timothy Tyree, Michael Metke and Cory Miller | Summary: Faces and voices are the dominant social signals used to recognize individuals amongst human and nonhuman primates (1–4). Yet it is not known how these critical signals are integrated into a cross-modal representation of individual identity in the primate brain. […]
