The Order of Free Energy Fluctuations in the Critical Sherrington-Kirkpatrick Model Revisited
Adrien Schertzer
We study the fluctuations of the free energy of the Sherrington-Kirkpatrick model at the critical inverse temperature . We prove that \[ \operatorname{Var}(F_N(1))\leq \frac1…

On the local nature of the de Almeida-Thouless line for mixed \(p\)-spin glasses
Jean-Christophe Mourrat, Adrien Schertzer
Jagannath and Tobasco~\cite{JagTob} proposed a generalized de Almeida-Thouless (AT) criterion aimed at characterizing the replica symmetric (RS) regime for a broad class of mixed \…

On the Replica Symmetry of a Variant of the Sherrington-Kirkpatrick Spin Glass
Christian Brennecke, Adrien Schertzer
We consider i.i.d. Ising spins with mean whose interactions are described by a Sherrington-Kirkpatrick Hamiltonian with a quartic correction. This model was recen…
