Research paperExperimental CharacterizationBroadband Terahertz Time-domain Spectroscopy of Quantum Materials in a Dilution RefrigeratorR. J. Vukelich, T. Norden, T. G. Hastings, M. Giri et al.arXiv preprint·2026·10.1103/physrevb.82.125110·arXiv:2601.11506AbstractWe have constructed a terahertz time domain spectroscopy system using a Bluefors dilution refrigerator with a 7 T split-coil magnet. Using a gallium arsenide single quantum well sample, terahertz waveforms were measured at 145 mK in a magnetic field range from 0 to 6 Tesla to measure cyclotron resonance. Effective mass is found to be 0.073me, which is larger than the commonly accepted bulk value of 0.068me.Read more
