Hyperinvariant Spin Network States -- An AdS/CFT Model from First Principles
Fynn Otto, Refik Mansuroglu, Norbert Schuch +2
We study the existence and limitations of hyperinvariant tensor networks incorporating a local SU(2) symmetry. As discrete implementations of the anti de-Sitter/conformal field the…
Emergent Thiemann coherent states in the near-kernel sector of quantum reduced loop gravity
Ilkka Mäkinen, Hanno Sahlmann, Waleed Sherif
We study the near-kernel sector of the Hamiltonian constraint operator in the one-vertex model of quantum reduced loop gravity using variational Monte Carlo methods with neural qua…
Finding and characterising physical states of Euclidean Abelianized loop quantum gravity using neural quantum states
Hanno Sahlmann, Waleed Sherif
We study physical (near-kernel of constraints) states of 4-d Euclidean loop quantum gravity in Smolin's weak coupling limit on the complete graph using variational Monte Carl…
Multipartite entanglement in the quantum tetrahedron
Robert Amelung, Hanno Sahlmann
The space of SU(2)-invariant four-valent tensors, also known as intertwiners, can be understood as the quantum states of a tetrahedron in Euclidean…
Dust shell in effective loop quantum black hole model
Hanno Sahlmann, Cong Zhang
In this work, the dynamics of a dust shell in an effective theory of spherically symmetric gravity containing quantum corrections from loop quantum gravity is investigated. To prov…
Bell states for fermions in loop quantum gravity
Hanno Sahlmann, Martin ZeiÃ
Fermion fields are fundamental for the description of nature and also fit very naturally into the framework of loop quantum gravity. Motivated partially by proposals to use gravita…
