Characterizing barren plateaus in quantum ansätze with the adjoint representation [PDF]

open access: goldNature Communications, 2023
Variational quantum algorithms, a popular heuristic for near-term quantum computers, utilize parameterized quantum circuits which naturally express Lie groups.

The canonical basis of the quantum adjoint representation [PDF]

open access: greenJournal of Combinatorial Algebra, 2016
We identify the canonical basis of the quantum adjoint representation of a quantized enveloping algebra with a basis that we defined before the theory of canonical bases was available.

Decomposition of the Adjoint Representation of the Small Quantum sl 2 [PDF]

open access: greenCommunications in Mathematical Physics, 1997
1.1. Given a finite type root datum and a primitive root of unity q = l √ 1, G. Lusztig has defined in [Lu] a remarkable finite dimensional Hopf algebra u over the cyclotomic field Q( l √ 1). It is called a restricted quantum universal enveloping algebra,

Spectrum and mass anomalous dimension of SU(2) gauge theories with fermions in the adjoint representation: from $N_f=1/2$ to $N_f=2$ [PDF]

open access: green, 2017
We summarize our results concerning the spectrum and mass anomalous dimension of SU(2) gauge theories with various numbers of fermions in the adjoint representation, where each Majorana fermion corresponds effectively to half a Dirac flavour $N_f$.

Three-dimensional QCD in the adjoint representation and random matrix theory [PDF]

open access: green, 2000
In this paper we complete the derivations of finite volume partition functions for QCD using random matrix theories by calculating the effective low-energy partition function for three-dimensional QCD in the adjoint representation from a random matrix ...

Finite-temperature chiral transition in QCD with quarks in the fundamental and adjoint representation [PDF]

open access: hybrid, 2005
We study the nature of the finite-temperature chiral transition in QCD with N_f light quarks in the fundamental and adjoint representation. Universality and renormalization-group (RG) arguments show that the possibility of having a continuous ...

A category for the adjoint representation [PDF]

open access: green, 2000
We construct an abelian category C and exact functors in C which on the Grothendieck group descend to the action of a simply laced quantum group in its adjoint representation. The braid group action in the adjoint representation lifts to an action in the

Lie Supergroups Obtained from 3-Dimensional Lie Superalgebras Associated to the Adjoint Representation and Having a 2-Dimensional Derived Ideal [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2008
We give the explicit multiplication law of the Lie supergroups for which the base manifold is a 3-dimensional Lie group and whose underlying Lie superalgebra g=g0⊕g1 which satisfies g1=g0, g0 acts on g1 via the adjoint representation and g0 has a 2 ...

When ancient numerical demons meet physics-informed machine learning: adjoint-based gradients for implicit differentiable modeling [PDF]

open access: yesHydrology and Earth System Sciences
Recent advances in differentiable modeling, a genre of physics-informed machine learning that trains neural networks (NNs) together with process-based equations, have shown promise in enhancing hydrological models' accuracy, interpretability, and ...

The kernel of the adjoint representation of a p-adic Lie group need not have an abelian open normal subgroup

open access: green, 2014
Let G be a p-adic Lie group and Ad be the adjoint representation of G on its Lie algebra. It was claimed in the literature that the kernel K of Ad always has an abelian open normal subgroup.
