Hyperbolic Monopoles, (Semi-)Holomorphic Chern-Simons Theories, and Generalized Chiral Potts Models
Seyed Faroogh Moosavian, Masahito Yamazaki, Yehao Zhou
We study the relation between spectral data of magnetic monopoles in hyperbolic space and the curve of the spectral parameter of generalized chiral Potts models (gCPM) through the…
5d-4d Correspondence in Twisted M-theory on a Conifold
Meer Ashwinkumar, Mir Faizal, Arshid Shabir +2
We study twisted M-theory in a general conifold background, and describe it in terms of a 5d non-commutative Chern-Simons-matter theory, which is equivalent to 5d non-commutative C…
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…
Affine -algebras and Miura maps from 3d non-Abelian quiver gauge theories
Ioana Coman, Myungbo Shim, Masahito Yamazaki +1
We study Vertex Operator Algebras (VOAs) obtained from the H-twist of 3d linear quiver gauge theories. We find that H-twisted VOAs can be regarded as the ''chiraliz…
Deformed Double Current Algebras, Matrix Extended Algebras, Coproducts, and Intertwiners from the M2-M5 Intersection
Davide Gaiotto, Miroslav Rapčák, Yehao Zhou
We study the algebraic structures which govern the deformation of supersymmetric intersections of M2 and M5 branes. The universal algebras on M2 and M5 branes are deformed double c…
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…
Decomposition of superconformal minimal models and their fractional quantum Hall wavefunctions
Yichen Hu, Sirui Ning, Yehao Zhou
superconformal minimal models are the first series of unitary conformal field theories (CFTs) extending beyond Virasoro algebra. Using coset constructions, we chara…
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…
Evidence for an algebra of instantons II
Jihwan Oh, Yehao Zhou
Building on our previous work [2109.01110], we will compute a new kind of instanton partition function. By doing so, we complete a set of building blocks of the instanton par…
2d BF Theory Coupled to 1d Quantum Mechanics: The Phase Space and Its Quantization
Seyed Faroogh Moosavian, Yehao Zhou
We study the ring of functions on the (classical and quantized) phase space of 2-dimensional BF theory with the gauge group coupled to a 1-dimensional quantum mecha…
Evidence for an Algebra of Instantons
Michele Del Zotto, Jihwan Oh, Yehao Zhou
In this short note, we present some evidence towards the existence of an algebra of BPS instantons. These are instantonic configurations that govern the partition functions o…
A domain wall in twisted M-theory
Jihwan Oh, Yehao Zhou
We study a four-dimensional domain wall in twisted M-theory. The domain wall is engineered by intersecting D6 branes in the type IIA frame. We identify the classical algebra of ope…
Twisted holography of defect fusions
Jihwan Oh, Yehao Zhou
In the twisted M-theory setting, various types of fusion of M2 and M5 branes induce coproducts between the algebra of operators on M2 branes and the algebra of operators on M5 bran…
Feynman diagrams and -deformed M-theory
Jihwan Oh, Yehao Zhou
We derive the simplest commutation relations of operator algebras associated to M2 branes and an M5 brane in the -deformed M-theory, which is a natural set-up for Twisted hologr…
On the Existence of Heterotic-String and Type-II-Superstring Field Theory Vertices
Seyed Faroogh Moosavian, Yehao Zhou
We consider two problems associated to the space of Riemann surfaces that are closely related to string theory. We first consider the problem of existence of heterotic-string and t…
Note on global symmetry and SYK model
Junyu Liu, Yehao Zhou
The goal of this note is to explore the behavior of effective action in the SYK model with general continuous global symmetries. A global symmetry will decompose the whole Hamilton…
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…
No Particle Production in Two Dimensions: Recursion Relations and Multi-Regge Limit
Barak Gabai, Dalimil Mazac, Andrei Shieber +2
We introduce high-energy limits which allow us to derive recursion relations fixing the various couplings of Lagrangians of two-dimensional relativistic quantum field theories with…
Note on Green Function Formalism and Topological Invariants
Yehao Zhou, Junyu Liu
It has been discovered previously that the topological order parameter could be identified from the topological data of the Green's function, namely the (generalized) TKNN invarian…
On thermalization in the SYK and supersymmetric SYK models
Nicholas Hunter-Jones, Junyu Liu, Yehao Zhou
The eigenstate thermalization hypothesis is a compelling conjecture which strives to explain the apparent thermal behavior of generic observables in closed quantum systems. Althoug…
Supersymmetric SYK model and random matrix theory
Tianlin Li, Junyu Liu, Yuan Xin +1
In this paper, we investigate the effect of supersymmetry on the symmetry classification of random matrix theory ensembles. We mainly consider the random matrix behaviors in the $\…
Syzygies Probing Scattering Amplitudes
Gang Chen, Junyu Liu, Ruofei Xie +2
We propose a new efficient algorithm to obtain the locally minimal generating set of the syzygies for an ideal, i.e. a generating set whose proper subsets cannot be generating sets…
