A Mermin--Wagner theorem on Lorentzian triangulations with quantum spins
M. Kelbert, Yu. Suhov, A. Yambartsev
We consider infinite random casual Lorentzian triangulations emerging in quantum gravity for critical values of parameters. With each vertex of the triangulation we associate a Hil…
A Mermin--Wagner theorem for Gibbs states on Lorentzian triangulations
M. Kelbert, Yu. Suhov, A. Yambartsev
We establish a Mermin--Wagner type theorem for Gibbs states on infinite random Lorentzian triangulations (LT) arising in models of quantum gravity. Such a triangulation is naturall…
A quantum Mermin--Wagner theorem for a generalized Hubbard model on a 2D graph
Mark Kelbert, Yurii Suhov
This paper is the second in a series of papers considering symmetry properties of a bosonic quantum system over an 2D graph, with continuous spins, in the spirit of the Mermin--Wag…
A quantum Mermin--Wagner theorem for quantum rotators on two--dimensional graphs
Mark Kelbert, Yurii Suhov
This is the first of a series of papers considering symmetry properties of quantum systems over 2D graphs or manifolds, with continuous spins, in the spirit of the Mermin--Wagner t…
