Observation of far-from-equilibrium scaling in the transient dynamics of 2D quantum magnets
Fabio Bensch, Umberto Borla, Federico Balducci +7
The transient regime of far-from-equilibrium quantum many-body dynamics lacks the established organizing principles that universality and scaling provide in equilibrium. It is leas…
(Non-)Traversable Quantum Phase Transitions
Federico Balducci, Paul M. Schindler, Andrea Solfanelli +1
Quantum phase transitions manifest as an abrupt change in the ground state of a many-body system; yet it is an open question whether this sudden change necessarily precludes a cont…
Domain coarsening in fractonic systems: a cascade of critical exponents
Jacopo Gliozzi, Federico Balducci, Giuseppe De Tomasi
We study the dynamics of domain growth when multipole moments of the order parameter are conserved. Following a quench into the ordered phase of the Ising model, the typical size o…
Non-Hermitian Multipole Skin Effects Challenge Localization
Jacopo Gliozzi, Federico Balducci, Taylor L. Hughes +1
We study the effect of quenched disorder on the non-Hermitian skin effect in systems that conserve a U(1) charge and its associated multipole moments. In particular, we generalize…
Symmetry re-breaking in an effective theory of quantum coarsening
Federico Balducci, Anushya Chandran, Roderich Moessner
We present a simple theory accounting for two central observations in a recent experiment on quantum coarsening and collective dynamics on a programmable quantum simulator [T. Mano…
The deep Hilbert space of all-to-all interacting SU(3) atoms: from quantum to classical
Federico Balducci, Aleksandra A. Ziolkowska
We study the emergence of chaos in multilevel atoms with all-to-all interactions, inspired by cavity QED. Focusing on a 3-level Tavis-Cummings model in a far detuned limit, we deta…
