rationale of the research: 
Entire fundamental physics boils down to just two frameworks or principles: quantum mechanics and general relativity. But it is extra ordinarily difficult to reconcile these two pillars of theoretical physics. 
Black holes are unique in embodying principles of both quantum mechanics and general relativity. Many of the difficulties reconciling these to pillars into one, can be traced back to puzzles about microscopic descriptions of black holes. This is well studied in string theory for the case of supersymmetric black holes. But supersymmetry has not been found in real world yet. A middle ground is offered by extremal non-supersymmetric black holes, which are closer to reality yet offer some analytic handle. Thus I intend to continue my study of such black holes. its scientific objectives: 
My broad goal is to understand - what kind of many body system a non-supersymmetric black hole is? This can be broken down to several specific questions.
1. Since an extremal non-supersymmetric black hole hosts a unique ground state [arXiv:2411.11096], what explains the zero temperature entropy of such black holes? 
2. Black holes have been argued to be the most chaotic systems in nature (arXiv:1412.6087). How does this manifest in microscopic descriptions?
3. In string theory are pictured as large molecules, i.e. bound states of more fundamental objects. For large molecules such as proteins, a key tool in understanding their chemical properties is to study the energy landscape. What do similar studies reveal for black holes? 4. Recall world black holes form from collapse of matter. Given that black holes microstates are well understood and analogs of molecular clouds also exist in the same settings (JHEP07(2024)123), can we find microscopic analog of black hole formation ? 5. Similarities between black holes and strange metals are long known. I have argued that the similarity perhaps stems from the presence of large number of low lying states in both systems and have shown that this qualitatively explains low temperature thermodynamics of near-extremal black holes. I intend to explore these connections further, especially if many low lying states can explain the temperature dependence of the resistivity of strange metals. 
 what hypothesis/model to be tested:
We shall use string theory to construct microscopic descriptions of such black holes, such as [arXiv:2411.11096]. Similar constructions have been very successful in explaining the entropy of supersymmetric black holes [JHEP 10(2014)186, JHEP 04(2016)082]. the main experiments to be carried out: The proposed research is entirely theoretical, hence only requires analytic calculations and numerical explorations needed. significance to the field:
The questions posed are as important as they are cutting edge. They would amount to a taking a big step towards understanding the presently obscure microscopic dynamics real life black holes.
