de Sitter Excited State in Heterotic E_8 x E_8 Theory Open
We devise a novel duality sequence to study late-time cosmology in the heterotic E_8 x E_8 setup of Horava and Witten with dynamical walls that are moving towards each other. Surprisingly, we find that the dimensionally reduced four-dimens…

de Sitter State in Heterotic String Theory Open
Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out suc…

torus link invariants in the large limit from the matrix model approach Open
In this paper we study U(N) colored HOMFLY-PT polynomials of torus links in the double scaling limit (polynomial variable q→1, N→∞ keeping qN fixed). We show that, in this limit, the colored HOMFLY-PT polynomial of any (Lα,Lβ) torus link c…

$U(N)$ Torus Link Invariants in the Large $N$ limit from Matrix Model Approach Open
In this paper we study $U(N)$ colored HOMFLY-PT polynomials of torus links in the double scaling limit (polynomial variable $q\rightarrow 1$, $N\rightarrow \infty$ keeping $q^N$ fixed). We show that, in this limit, the colored HOMFLY-PT po…

Coherent states in M-theory: A brane scan using the Taub-NUT geometry Open
The Taub-NUT geometry corresponds to the Kaluza-Klein monopole solution of M-theory and on dimension reduction along the Taub-NUT circle direction it becomes the D6 brane of type IIA string theory. We show that the Taub-NUT geometry can be…

The Generalized OTOC from Supersymmetric Quantum Mechanics—Study of Random Fluctuations from Eigenstate Representation of Correlation Functions Open
The concept of the out-of-time-ordered correlation (OTOC) function is treated as a very strong theoretical probe of quantum randomness, using which one can study both chaotic and non-chaotic phenomena in the context of quantum statistical …

Late time dynamics in SUSY saddle-dominated scrambling through higher-point OTOC Open
In this article, we study the scrambling dynamics in supersymmetric quantum mechanical systems. The eigenstate representation of such supersymmetric systems allows us to present an explicit form of the $2N$-point out-of-time-order correlat…

Generalized out-of-time-order correlator in supersymmetric quantum mechanics using tensor product formalism Open
In this article we study the presence of chaos in supersymmetric(SUSY) quantum mechanics. For that purpose we present a form of 4-point out of time order correlator(OTOC) for SUSY quantum mechanical systems using tensor product formalism. …
