1. Generalized hot attractors / Goldstein, Kevin ; Jejjala, Vishnu ; Mashiyane, James ; Nampuri, Suresh
Non-extremal black holes are endowed with geometric invariants related to their horizon areas. [...]

2. The hot attractor mechanism: decoupling without deep throats / Goldstein, Kevin ; Jejjala, Vishnu ; Nampuri, Suresh
Non-extremal black holes in N = 2 $$ \mathcal{N}=2 $$ supergravity have two horizons, the geometric mean of whose areas recovers the horizon area of the extremal black hole obtained from taking a smooth zero temperature limit. [...]

3. A Calogero formulation for four-dimensional black-hole microstates / Lechtenfeld, Olaf ; Nampuri, Suresh
We extract the leading-order entropy of a four-dimensional extremal black hole in N=2 ungauged supergravity by formulating the CFT 1 that is holographically dual to its near-horizon AdS 2 geometry, in terms of a rational Calogero model with a known counting formula for the degeneracy of states in its Hilbert space..

4. Hot attractors / Goldstein, Kevin ; Jejjala, Vishnu ; Nampuri, Suresh
The product of the areas of the event horizon and the Cauchy horizon of a non-extremal black hole equals the square of the area of the horizon of the black hole obtained from taking the smooth extremal limit. [...]

5. Attractive holographic c -functions / Bhattacharyya, Arpan ; Haque, S. ; Jejjala, Vishnu ; Nampuri, Suresh ; et al
Using the attractor mechanism for extremal solutions in N = 2 $$ \mathcal{N}=2 $$ gauged supergravity, we construct a c -function that interpolates between the central charges of theories at ultraviolet and infrared conformal fixed points corresponding to anti-de Sitter geometries. [...]
