One-dimensional long-range Ising model: two (almost) equivalent approximations
Valerio Pagni, Guido Giachetti, Andrea Trombettoni +1
We investigate the critical behavior of the one-dimensional Ising model with long-range interactions using the functional renormalization group in the local potential approximation…
Lagrangian Homotopy Analysis Method using the Least Action Principle
Gervais Nazaire Chendjou Beukam, Jean Pierre Nguenang, Stefano Ruffo +1
The Homotopy Analysis Method (HAM) is a powerful technique which allows to derive approximate solutions of both ordinary and partial differential equations. We propose to use a var…
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…
Conformal order and Poincar-Klein mapping underlying electrostatics-driven inhomogeneity in tethered membranes
Honghui Sun, Zhenwei Yao
Understanding the organization of matter under the long-range electrostatic force is a fundamental problem in multiple fields. In this work, based on the electrically charged tethe…
Catalysis of quantum tunneling by ancillary system learning
Renzo Testa, Alex Rodriguez, Alberto d'Onofrio +3
Given the key role that quantum tunneling plays in a wide range of applications, a crucial objective is to maximize the probability of tunneling from one quantum state/level to ano…
Non-equilibrium steady states of long-range coupled harmonic chains
Francesco Andreucci, Stefano Lepri, Stefano Ruffo +1
We perform a numerical study of transport properties of a one-dimensional chain with couplings decaying as an inverse power of the intersite distance and open boun…
