Holographic Stirling engines and the route to Carnot efficiency
Nikesh Lilani, Manus R. Visser
We compute the efficiency of the reversible Stirling engine, with and without regeneration, for a broad class of working substances including Van der Waals fluids, quantum ideal ga…
Comparative study of the butterfly velocity in holographic QCD models at finite temperature and chemical potential
Nikesh Lilani, Dilpreet Sandhu, Subhash Mahapatra
In this work, we study quantum chaos in a variety of holographic QCD models at finite temperature and chemical potentials. This includes the 1 R-Charge black hole (1RCBH) model, th…
Heat engines for scale invariant systems dual to black holes
Nikesh Lilani, Manus R. Visser
According to holography, a black hole is dual to a thermal state in a strongly coupled quantum system. One of the best-known examples of holography is the Anti-de Sitter/Conformal…
Chaos in hyperscaling violating Lifshitz theories
Nikesh Lilani
We holographically study quantum chaos in hyperscaling-violating Lifshitz (HVL) theories (with charge). Specifically, we present a detailed computation of the out-of-time ordered c…
Enhancing Ionic Conductivity of ceramic Na3Zr2Si2PO12 via NaI Substitution
Aditya Sekhar, Nikesh Lilani, M. Dinachandra Singh
The high ionic conducting sodium superionic conductor Na3Zr2Si2PO12 -NaI composites have been prepared successfully via solid state reaction route. As the NaI content increases, th…
