Consistency between reflection M-EELS and optical spectroscopy measurements of the long-wavelength density response of BiSrCaCuO
Jin Chen, Xuefei Guo, Christian Boyd +11
The density fluctuation spectrum captures many fundamental properties of strange metals. Using momentum-resolved electron energy-loss spectroscopy (M-EELS), we recently showed that…
Anomalous high-temperature THz nonlinearity in superconductors near the metal-insulator transition
Dipanjan Chaudhuri, David Barbalas, Ralph Romero +5
The interplay of strong disorder and superconductivity is a topic of long-term interest in condensed matter physics. Here we explore the nonlinear THz response of superconducting N…
An optical investigation of the heavy fermion normal state in superconducting UTe
Sirak M. Mekonen, Chang-Jong Kang, Dipanjan Chaudhuri +5
The recently discovered superconductor, UTe, has attracted immense scientific interest due to the experimental observations that suggest odd-parity superconductivity. It is bel…
Ambipolar magneto-optical response of ultra-low carrier density topological insulators
Dipanjan Chaudhuri, Maryam Salehi, Sayak Dasgupta +5
We have investigated the THz range magneto-optical response of ultralow carrier density films of SbTe using time-domain THz polarimetry. Undoped SbTe has a chemical…
Observation of a marginal Fermi glass using THz 2D coherent spectroscopy
Fahad Mahmood, Dipanjan Chaudhuri, Sarang Gopalakrishnan +2
A longstanding open problem in condensed matter physics is whether or not a strongly disordered interacting insulator can be mapped to a system of effectively non-interacting local…
Impact of the lattice on magnetic properties and possible spin nematicity in the S=1 triangular antiferromagnet NiGaS
Michael E. Valentine, Tomoya Higo, Yusuke Nambu +5
NiGaS is a triangular lattice S=1 system with strong two-dimensionality of the lattice, actively discussed as a candidate to host spin-nematic order brought about by strong…
