Phase diagram of the one-dimensional three-state Potts model with an additional mean-field interaction
Alessandro Campa, Vahan Hovhannisyan, Stefano Ruffo +1
We derive the phase diagram of the one-dimensional three-state Potts model with an additional mean-field interaction in the canonical ensemble. The free energy is obtained by mappi…
Ensemble Inequivalence in Ising Chains with Competing Interactions
Alessandro Campa, Vahan Hovhannisyan, Stefano Ruffo +1
We study the effect of competing interactions on ensemble inequivalence. We consider a one-dimensional Ising model with ferromagnetic mean-field interactions and short-range neares…
Form follows Function: Text-to-Text Conditional Graph Generation based on Functional Requirements
Peter A. Zachares, Vahan Hovhannisyan, Alan Mosca +1
This work focuses on the novel problem setting of generating graphs conditioned on a description of the graph's functional requirements in a downstream task. We pose the problem as…
Fast Multilevel Algorithms for Compressive Principle Component Pursuit
Vahan Hovhannisyan, Yannis Panagakis, Panos Parpas +1
Recovering a low-rank matrix from highly corrupted measurements arises in compressed sensing of structured high-dimensional signals (e.g., videos and hyperspectral images among oth…
