Classifying fusion rules of anyons or SymTFTs: A general algebraic formula for domain wall problems and quantum phase transitions
We propose a formula for the transformation law of anyons in topologically ordered phases or topological quantum field theories (TQFTs) through a gapped or symmetry-preserving domain wall. Our…

Shell formulas for instantons and gauge origami
We introduce the shell formula-a framework that unifies the description of partition functions whose pole structures are classified by Young diagrams of arbitrary dimension. The formalism yields…

Bulk-cone singularities and echoes from AdS exotic compact objects
The region near a black hole horizon may be modified by quantum gravity effects that resolve the singularity. Such geometry may be represented by an exotic compact object. Because the horizon is…

Entanglement wedge cross section triangle information and holographic entanglement of assistance
We identify a non-negative and upper-bounded entanglement signal in holography which is defined as a combination of entanglement wedge cross sections (EWCS) for a tripartite mixed state ABE:…

Sp(4,Z) modular inflation
We investigate inflation models governed by the Siegel modular group Sp(4,Z). The Sp(4,Z) group extends the SL(2,Z) framework from one modulus to three moduli while…

Constructing the Padmanabhan Holographic Model in a BIonic System
Recently, Padmanabhan has argued that a difference between the number of degrees of freedom on the surface and the number in a bulk causes the expansion of the universe. We can reconsider this idea…

Generators of a Bosonic VOA and Connections to a Boundary VOA
We show how to identify generators of bosonic VOAs associated with T[n-1,1][1n](SU(n)) and T[n-1,12][2,1n-1](SU(n+1)), and conjecture that the algebraic structure of these VOAs…

Aspects of holographic timelike entanglement entropy in black hole backgrounds
We study the holographic construction of timelike entanglement entropy (tEE) in black hole backgrounds in Lorentzian geometries. The holographic tEE is realized through extremal surfaces consisting…

Crossing symmetry of OPE statistics
We study the crossing symmetry of the ensemble of large-c 2D CFTs defined through 3D gravity. A central observation is that statistical moments of OPE coefficients are not independent; rather,…

Twisted Feynman Integrals: from generating functions to spin-resummed post-Minkowskian dynamics
We propose to call a class of deformed Feynman integrals as twisted Feynman integrals, where the integrand has an additional exponential factor linear in loop momenta. Such integrals appear in…

OTOC and Quamtum Chaos of Interacting Scalar Fields
Discretizing the λϕ4 scalar field theory on a lattice yields a system of coupled anharmonic oscillators with quadratic and quartic potentials. We begin by analyzing the two coupled oscillators in…
