Impact of electron correlations on two-particle charge response in electron- and hole-doped cuprates
Abhishek Nag, Luciano Zinni, Jaewon Choi +13
Estimating many-body effects that deviate from an independent particle approach, has long been a key research interest in condensed matter physics. Layered cuprates are prototypica…
Novel magnetic excitations beyond the single- and double-magnons
Hebatalla Elnaggar, Abhishek Nag, Maurits W. Haverkort +2
Conventional wisdom suggests that one photon that carries one unit of angular momentum can change the spin angular momentum of a magnetic system with one unit (delta Ms = +-1) at m…
Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet
A. Nag, A. Nocera, S. Agrestini +5
The microscopic origins of emergent behaviours in condensed matter systems are encoded in their excitations. In ordinary magnetic materials, single spin-flips give rise to collecti…
