Obtaining insight into microscopic cooperative effects is a fascinating topic in condensed matter research because, through self-coordination and collectivity, they can lead to instabilities with macroscopic impacts like phase transitions. We used femtosecond time- and angle-resolved photoelectron spectroscopy (trARPES) to optically pump and probe TbTe3, an(More)
Employing the momentum sensitivity of time- and angle-resolved photoemission spectroscopy we demonstrate the analysis of ultrafast single- and many-particle dynamics in antiferromagnetic EuFe(2)As(2). Their separation is based on a temperature-dependent difference of photoexcited hole and electron relaxation times probing the single-particle band and the(More)
In complex materials various interactions have important roles in determining electronic properties. Angle-resolved photoelectron spectroscopy (ARPES) is used to study these processes by resolving the complex single-particle self-energy and quantifying how quantum interactions modify bare electronic states. However, ambiguities in the measurement of the(More)
Title Inter-and intra-laminar subcircuits of excitatory and inhibitory neurons in layer 6a of the rat barrel cortex. 2 discussions, Lorna Rettig for helpful comments. We are indebted to Kevan Martin for invaluable discussions, support and for reading previous versions of this manuscript. Abstract Approximately half the excitatory neurons in layer 6 (L6) of(More)
