Universality of Gaussian-Mixture Reverse Kernels in Conditional Diffusion
Nafiz Ishtiaque, Syed Arefinul Haque, Kazi Ashraful Alam +1
We prove that conditional diffusion models whose reverse kernels are finite Gaussian mixtures with ReLU-network logits can approximate suitably regular target distributions arbitra…
Refined Invariants and Quantum Curves from Supersymmetric Localization
Sibasish Banerjee, Nafiz Ishtiaque, Saebyeok Jeong
We study an Aganagic-Vafa brane supported on a special Lagrangian submanifold in a non-compact toric Calabi-Yau threefold . From the perspective of geome…
R-matrices and Miura operators in 5d Chern-Simons theory
Nafiz Ishtiaque, Saebyeok Jeong, Yehao Zhou
We derive Miura operators for - and -algebras from first principles as the expectation value of the intersection between a topological line defect and a holomorphic surface d…
Symmetry topological field theory and non-abelian Kramers-Wannier dualities of generalised Ising models
Clement Delcamp, Nafiz Ishtiaque
For a class of two-dimensional Euclidean lattice field theories admitting topological lines encoded into a spherical fusion category, we explore aspects of their realisations as bo…
Elliptic Stable Envelopes for Certain Non-Symplectic Varieties and Dynamical -Matrices for Superspin Chains from the Bethe/Gauge Correspondence
Nafiz Ishtiaque, Seyed Faroogh Moosavian, Yehao Zhou
We generalize Aganagic-Okounkov's theory of elliptic stable envelopes, and its physical realization in Dedushenko-Nekrasov's and Bullimore-Zhang's works, to certain varieties witho…
Line Operators in 4d Chern-Simons Theory and Cherkis Bows
Nafiz Ishtiaque, Yehao Zhou
We show that the phase spaces of a large family of line operators in 4d Chern-Simons theory with gauge group are given by Cherkis bow varieties with crosses. Thes…
Superspin chains from superstring theory
Nafiz Ishtiaque, Seyed Faroogh Moosavian, Surya Raghavendran +1
We present a correspondence between two-dimensional supersymmetric gauge theories and rational integrable spin chains with spin variables…
Disk, interval, point: on constructions of quantum field theories with holomorphic action functionals
Nafiz Ishtiaque, Junya Yagi
Bosonic quantum field theories with holomorphic action functionals are realized by two types of constructions involving supersymmetric quantum field theories, compactified on an in…
Topological Holography: The Example of The D2-D4 Brane System
Nafiz Ishtiaque, Seyed Faroogh Moosavian, Yehao Zhou
We propose a toy model for holographic duality. The model is constructed by embedding a stack of D2-branes and D4-branes (with one dimensional intersection) in a 6D topolog…
2D BPS Rings from Sphere Partition Functions
Nafiz Ishtiaque
We consider extremal correlation functions, involving arbitrary number of BPS (chiral or twisted chiral) operators and exactly one anti-BPS operator in 2D N=(2,2) theories. These c…
Correlation Functions of Coulomb Branch Operators
Efrat Gerchkovitz, Jaume Gomis, Nafiz Ishtiaque +3
We consider the correlation functions of Coulomb branch operators in four-dimensional N=2 Superconformal Field Theories (SCFTs) involving exactly one anti-chiral operator. These ex…
Kahler Potential and Ambiguities in 4d N=2 SCFTs
Jaume Gomis, Nafiz Ishtiaque
The partition function of four-dimensional N=2 superconformal field theories on S^4 computes the exact Kahler potential on the space of exactly marginal couplings [1]. We present a…
Renormalization group analysis of the singularity structure of effective potentials
T. Hanif, N. Ishtiaque
Using the renormalization group techniques it was previously shown that the perturbative effective potential in the symmetric theory, massless scalar electro…
Modeling Electronic and Thermal Characteristics of Ge/Si-Core/Shell Nanowire Quantum Dot in the Coulomb Blockade Regime
Shah Mohammad Bahauddin, Nafiz Ishtiaque, Ishtiza Ibne Azad +1
We investigate the transport characteristics of Ge/Si-Core/Shell nanowire with Coulomb Blockade in presence of external magneto-electric fields from a theoretical basis. Using the…
