Translocation of links through a pore: effects of link complexity and size
Michele Caraglio, Enzo Orlandini, Stuart G Whittington
We have used Langevin dynamics to simulate the forced translocation of linked polymer rings through a narrow pore. For fixed size (i.e. fixed number of monomers) the translocation…
Effectof biquadratic exchange on the phase diagram of a spin-1 transverse XY modelwith single-ion anisotropy
I. Rabuffo, L. De Cesare, A. Caramico D'Auria +1
The two-time Green function method is employed to explore the effect of the biquadratic exchange interaction on the phase diagram of a -dimensional spin-1 transverse XY model wi…
Projective quantum Monte Carlo simulations guided by unrestricted neural network states
E. M. Inack, G. E. Santoro, L. Dell'Anna +1
We investigate the use of variational wave-functions that mimic stochastic recurrent neural networks, specifically, unrestricted Boltzmann machines, as guiding functions in project…
Cluster approximations for the TASEP: stationary state and dynamical transition
Alessandro Pelizzola, Marco Pretti
We develop and test cluster approximations, which generalize simple mean--field by taking into account more and more local correlations, for the Totally Asymmetric Simple Exclusion…
Experimental signatures of an absorbing-state phase transition in an open driven many-body quantum system
Ricardo Gutierrez, Cristiano Simonelli, Matteo Archimi +6
Understanding and probing phase transitions in non-equilibrium systems is an ongoing challenge in physics. A particular instance are phase transitions that occur between a non-fluc…
Duality and reciprocity of fluctuation-dissipation relations in conductors
Lino Reggiani, Eleonora Alfinito, Tilmann Kuhn
By analogy with linear-response we formulate the duality and reciprocity properties of current and voltage fluctuations expressed by Nyquist relations including the intrinsic bandw…
