On the Derivation of Twisted K-Theory from M-Theory

Nikita Golub, Hisham Sati, Urs Schreiber

In a restricted untwisted sector, Diaconescu, Moore & Witten (2000, 2003) gave a quantum M-theoretic consistency check, at the level of partition functions, of what one may call "H…

A TQFT-based Platform for Efficient Computation of Knot Invariants

Amena Al Rawi, Hisham Sati, Vivek Kumar Singh

We present an interactive web platform that unifies the construction Feynman ribbon diagrams (FRDs), the evaluation of higher-rank Chern--Simons knot invariants, and the identifica…

Higher Gauge Theory via Differential Nonabelian Cohomology

Hisham Sati, Urs Schreiber

This is a streamlined introduction to the global (infrared) completion of Maxwell-type higher gauge fields (as in the higher gauge sectors of higher dimensional supergravity and it…

Bistability of Exciton-Photon Microcavities in the Ultrastrong-Coupling Regime

Rashed Aljasmi, Hisham Sati, Hichem Eleuch

We investigate a coherently driven exciton--photon microcavity with Kerr nonlinearity in the ultrastrong-coupling regime. When the lower and upper polariton branches are well separ…

Higher Superspace Supergravity and its IR-Completions

Grigorios Giotopoulos, Hisham Sati, Urs Schreiber

It is an old idea that higher-dimensional super-gravity (SuGra) is put on-shell just by imposing Bianchi identities on super-field strengths over super-spacetimes subject to super-…

Flux Quantization on 10D Type IIA Superspace via Cyclification from 11D

Grigorios Giotopoulos, Hisham Sati

We produce the dimensional reduction to 10D IIA supergravity (SuGra), via cyclification, of the remarkable result that full 11D SuGra is put on shell just by imposing the duality-s…

Flux Quantization of Type IIA in Unstable K-Theory

Pinak Banerjee, Hisham Sati, Urs Schreiber

The traditional conjecture that RR-flux is quantized in stable K-cohomology fails to account for the presence of NS-brane sources: These impose nonlinear relations -- reductions of…

Bulk-Edge Correspondence via Higher Gauge Theory

Hisham Sati, Urs Schreiber

More profound than bulk topological order of quantum materials is only its unwinding via gapless excitations along boundaries of the sample. We recast this bulk-edge correspondence…

A Global Model Structure for -Linear -Local Systems

Hisham Sati, Urs Schreiber

Parameterized stable homotopy theory organizes local systems of spectra over homotopy types, governed by a "yoga" of six functors. To provide semantics for the recently developed L…

Non-Perturbative SDiff Covariance of Fractional Quantum Hall Excitations

Hisham Sati, Urs Schreiber

Collective excitations of Fractional Quantum Hall (FQH) liquids at long wavelengths are thought to be of a generally covariant geometric nature, governed by area-preserving diffeom…

Drinfeld Center as Quantum State Monodromy over Bloch Hamiltonians around Defects

Hisham Sati, Urs Schreiber

The Drinfeld center fusion category famously models anyons in certain lattice models. Here we demonstrate how its fusion rules may also describe topol…

Flux Quantization on M-Strings

Pinak Banerjee, Hisham Sati, Urs Schreiber

The electric Gauss law in 11D SuGra is famously non-linear, whence its flux quantization must be in nonabelian cohomology. We have previously shown that the minimal admissible choi…

FQH Liquids with Flux-Expulsion Islands allow Nonabelian Anyons

Hisham Sati, Urs Schreiber

The idea that topologically protected quantum states, such as anyons, may be attached to super/semiconductor heterostructures has received enormous attention, but experimental sign…

Synthetic Differential Jet Bundles are Reduced

Grigorios Giotopoulos, Igor Khavkine, Hisham Sati +1

We have previously observed that the theory of solutions of partial differential equations, regarded as diffieties inside jet bundles, acquires a powerful comonadic formulation aft…

Realization of staircase topological Anderson phase transitions

Marwa Mannai, Yaoyao Shu, Sonia Haddad +4

One-dimensional topological Anderson insulators provide a paradigm for disorder-induced topological phases in which the underlying system turns from a trivial to a topological phas…

Higher-Dimensional Anyons via Higher Cohomotopy

Sadok Kallel, Hisham Sati, Urs Schreiber

We highlight that integer Heisenberg groups at level 2 underlie topological quantum phenomena: their group algebras coincide with the algebras of quantum observables of abelian any…
