- 요약Many fascinating quantum phenomena, including quantum Hall effects, unconventional superconductivity, and correlated states in moire systems, are associated with energy gaps in the far-infrared regime. Low-energy excitations in these systems are rich and are crucial to understanding the nature of the underlying phases. Optical spectroscopy is a powerful probe to detect these excitations, especially when the excitations are charge neutral, which are hidden from charge-transport probes. However, their application at sub-Kelvin temperatures, where these phenomena are often best realized, is still severely limited. Here, I address the challenges of far-infrared spectroscopy at millikelvin temperatures and present a novel and versatile experimental platform enabling simultaneous far-infrared optical spectroscopy and electronic transport measurements on quantum materials at millikelvin temperatures. I demonstrate the power of this platform by showcasing photocurrent-based spectroscopy measurements of various two-dimensional materials. This includes far- and mid-infrared Landau-level spectroscopy of monolayer and bilayer graphene, providing insights into their behavior within the quantum Hall regime. Additionally, I present results from ongoing efforts to determine the nature of the possible quantum spin liquid state in 1T-TaS2 in both bulk and monolayer devices, including photocurrent resolved spectroscopy of far-infrared charge-neutral modes in 1T-TaS2. This platform paves the way for exploring a wide range of quantum materials, including superconductors, excitonic insulators, various quantum Hall states, and quantum spin liquids.
