70. Laplacian Renormalization Group for heterogeneous networks: information core and entropic transitions

Prof. Andrea Gabrielli (Dipartimento di Ingegneria, Università degli Studi "Roma Tre")

Complex networks usually exhibit a rich architecture organized over multiple intertwined scales. Information pathways are expected to pervade these scales reflecting structural insights that are not manifest from analyses of the network topology. Moreover, small-world effects correlate the different network hierarchies complicating the identification of coexisting mesoscopic structures and...

93. Trapping active particles up to the limiting case: bacteria enclosed in a biofilm

Prof. Chantal Valeriani (Universidad Complutense de Madrid)

Active matter systems are composed of constituents, each one in nonequilibrium, that consume energy in order
to move [1]. A characteristic feature of active matter is collective motion leading to nonequilibrium phase
transitions or large scale directed motion [2]. A number of recent works have featured active particles interacting with obstacles, either moving or fixed [3,4,5]. When an...

64. A condensation transition at equilibrium and out-of-equilibrium

Paolo Politi (Istituto Nazionale di Fisica Nucleare)

Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. At equilibrium there are well established results and we discuss different scenarios of the condensation trantition.
In the out-of-equilibrium setup we consider one of such models with two conservation laws, attached to two external reservoirs, R_1...

94. Quantum Simulations of Abelian Gauge Theories

Elisa Ercolessi (Istituto Nazionale di Fisica Nucleare)

We propose an implementation of a two-dimensional Z2 lattice gauge theory model on a shallow quantum circuit, involving a number of single- and two-qubit gates comparable to what can be achieved with present-day and near-future technologies. The ground-state preparation is numerically analyzed on a small lattice with a variational quantum algorithm, which requires a small number of parameters...
