Selective coupling of high-order phonons in La2-xSrxCuO4
Ke-Jun Xu, Paulina Majchrzak, Nathan Giles-Donovan +14
In crystals and molecules with strong coupling between the charge carriers and atomic vibrations, high order harmonics of the vibrational excitations can be observed with intensity…
Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…
Colossal magnetoresistance from spin-polarized polarons in an Ising system
Ying-Fei Li, Emily M. Been, Sudhaman Balguri +12
Recent experiments suggest a new paradigm towards novel colossal magnetoresistance (CMR) in a family of materials EuMX(M=Cd, In, Zn; X=P, As), distinct from the traditional…
Polaron Coherence Condensation as the Mechanism for Colossal Magnetoresistance in Layered Manganites
N. Mannella, W. L. Yang, K. Tanaka +8
Angle-resolved photoemission spectroscopy data for the bilayer manganite La1.2Sr1.8Mn2O7 show that, upon lowering the temperature below the Curie point, a coherent polaronic metall…
