Impurities or a neutral Fermi surface? A further examination of the low-energy ac optical conductivity of SmB
N. J. Laurita, C. M. Morris, S. M. Koohpayeh +3
Recent experiments have uncovered evidence of low energy excitations in the bulk of SmB that are perhaps associated with unconventional quasiparticles, bringing into question w…
Anomalous 3D bulk AC conduction within the Kondo gap of SmB single crystals
N. J. Laurita, C. M. Morris, S. M. Koohpayeh +5
The Kondo insulator SmB has long been known to display anomalous transport behavior at low temperatures, T K. In this temperatures range, a plateau is observed in the dc re…
Singlet-triplet excitations and long range entanglement in the spin-orbital liquid candidate FeSc2S4
N. J. Laurita, J. Deisenhofer, LiDong Pan +6
Theoretical models of the spin-orbital liquid (SOL) FeScS have predicted it to be in close proximity to a quantum critical point separating a spin-orbital liquid phase from…
Low Energy Electrodynamics of Novel Spin Excitations in the Quantum Spin Ice YbTiO
LiDong Pan, Se Kwon Kim, A. Ghosh +7
In condensed matter systems, the formation of long range order (LRO) with broken symmetry is often accompanied by new types of excitations. However, in many magnetic pyrochlore oxi…
A hierarchy of bound states in the 1D ferromagnetic Ising chain CoNbO investigated by high resolution time-domain terahertz spectroscopy
C. M. Morris, R. Valdés Aguilar, A. Ghosh +6
Kink bound states in the one dimensional ferromagnetic Ising chain compound CoNbO have been studied using high resolution time-domain terahertz spectroscopy in zero applied…
