The theory of so-called \u201cunconventional superconductors\u201d remains an extremely challenging area. Quantitative predictions are rare and it is difficult to find \u201csmoking guns\u201d that can provide experimental confirmation of a specific unconventional state.<\/p>\n<p>In <a href=\"https:\/\/arxiv.org\/abs\/1912.08160\">a recent paper<\/a> involving theorists in Kent, Barcelona, Bristol, and Budapest we present a quantitative theory of an unconventional superconductor. The material under investigation is LaNiGa<sub>2<\/sub>, which has attracted much interest in recent years. Our theory has a single adjustable parameter which we fix from experiments. We demonstrate that it accurately predicts the unusual temperature-dependence of the specific heat of this system and use it to predict a unique experimental signature (in the spin-resolved density of states) of the underlying exotic pairing state.<\/p>\n<p>It is interesting to note that the materials superconducting quantum computers are based on, namely \u201cconventional\u201d superconductors, have been well understood for over half a century. The lack of a detailed, microscopic understanding of unconventional superconductors severely limits our ability to exploit their unusual properties. Our recent work represents a step in that direction and could potentially provide a template for future predictive theories of other exotic superconducting materials. Experimental verification of our predictions would confirm this by making LaNiGa<sub>2<\/sub> the best-understood unconventional superconductor.<\/p>\n<p><em>This blog post first appeared in <a href=\"https:\/\/research.kent.ac.uk\/pqm\/2020\/03\/30\/quantitative-theory-of-triplet-pairing-in-the-unconventional-superconductor-laniga2\/\">research.kent.ac.uk\/pqm<\/a>.<\/em><\/p>\n<p><strong>Reference:<\/strong><\/p>\n<p>Sudeep Kumar Ghosh, G\u00e1bor Csire, Philip Whittlesea, James F.
