The Standard Models contain chiral fermions coupled to gauge theories. It has been a long-standing problem to give such gauged chiral fermion theories a quantum non-perturbative definition. By classification of quantum anomalies and symmetric invertible topological orders via a mathematical cobordism theorem for differentiable and triangulable manifolds, and the existence of symmetric gapped boundary for the trivial symmetric invertible topological orders, we propose that Spin(10) chiral… Expand
Ultra Unification
Strong, electromagnetic, and weak forces were unified in the Standard Model (SM) with spontaneous gauge symmetry breaking. These forces were further conjectured to be unified in a simple Lie groupExpand

Quantum 4d Yang-Mills theory and time-reversal symmetric 5d higher-gauge topological field theory
We explore various 4d Yang-Mills gauge theories (YM) living as boundary conditions of 5d gapped short-/long-range entangled (SRE/LRE) topological states. Specifically, we explore 4d time-reversalExpand
Anomaly Inflow and the η-Invariant
Perturbative fermion anomalies in spacetime dimension d have a well-known relation to ChernSimons functions in dimension D = d + 1. This relationship is manifested in a beautiful way in “anomalyExpand
Gauge Enhanced Quantum Criticality Beyond the Standard Model
Standard lore ritualizes our quantum vacuum in the 4-dimensional spacetime (4d) governed by one of the candidate Standard Models (SMs), while lifting towards one of Grand Unifications (GUTs) atExpand
Chiral Lattice Theories From Staggered Fermions
We construct lattice theories from reduced staggered fermions that we argue are capable of producing chiral theories in the continuum limit. The construction employs Yukawa interactions ofExpand
Comments on Symmetric Mass Generation in 2d and 4d
Symmetric mass generation is the name given to a mechanism for gapping fermions while preserving a chiral, but necessarily non-anomalous, symmetry. In this paper we describe how symmetric massExpand
Gauge Enhanced Quantum Criticality Between Grand Unifications: Categorical Higher Symmetry Retraction
Prior work [1] shows that the Standard Model (SM) naturally arises near a gapless quantum critical region between Georgi-Glashow (GG) su(5) and Pati-Salam (PS) su(4) × su(2) × su(2) models of quantumExpand

A lattice non-perturbative definition of an SO(10) chiral gauge theory and its induced standard model
The standard model is a chiral gauge theory where the gauge fields couple to the right-hand and the left-hand fermions differently. The standard model is defined perturbatively and describes allExpand
Solution to the 1+1 dimensional gauged chiral Fermion problem
We show that the 3450 U(1) chiral fermion theory can appear as the low energy effective field theory of a 1+1D local lattice model, with an on-site U(1) symmetry and finite-range interactions. TheExpand

A bstractAn approach to the formulation of chiral gauge theories on the lattice is to start with a vector-like theory, but decouple one chirality (the “mirror” fermions) using strong YukawaExpand
Symmetry-protected topological orders for interacting fermions: Fermionic topological nonlinear σ models and a special group supercohomology theory
Symmetry-protected topological (SPT) phases are gapped short-range-entangled quantum phases with a symmetry $G$, which can all be smoothly connected to the trivial product states if we break theExpand
