State preparation and detection for quantum simulation of particle collisions
Federica Maria Surace, Sary Bseiso, John Preskill
Simulating the real-time dynamics of particle collisions is a promising application of quantum simulators, because classical methods such as tensor networks struggle to capture the…
Charge Transport Capacity as a Probe of Resonances in Models of Many-Body Localization
Jessica Kaijia Jiang, Federica Maria Surace, Olexei I. Motrunich
The fate of Many-Body Localization (MBL) in the thermodynamic limit remains elusive, partly because numerical studies suffer from unexplained finite-size effects. We introduce and…
Weak integrability breaking perturbations in classical integrable models on the lattice
Sara Vanovac, Catherine McCarthy, Federica Maria Surace +1
We show how to systematically construct weak integrability breaking perturbations (WIBs) for classical integrable models on the lattice. These perturbations, which allow quasi-cons…
Quasiconservation Laws and Suppressed Transport in Weakly Interacting Localized Models
Jessica Kaijia Jiang, Federica Maria Surace, Olexei I. Motrunich
The stability of localization in the presence of interactions remains an open problem, with finite-size effects posing significant challenges to numerical studies. In this work, we…
Quantum simulation of bubble nucleation across a quantum phase transition
De Luo, Federica Maria Surace, Arinjoy De +8
The liquid-vapor transition is a classic example of a discontinuous (first-order) phase transition. Such transitions underlie many phenomena in cosmology, nuclear and particle phys…
The Ising dual-reflection interface: symmetry and Majorana strong zero modes
Juliane Graf, Federica Maria Surace, Marcus Berg +1
We investigate an interface in the transverse field quantum Ising chain connecting an ordered ferromagnetic phase and a disordered paramagnetic phase that are Kramers-Wannier duals…
Probing false vacuum decay on a cold-atom gauge-theory quantum simulator
Zi-Hang Zhu, Ying Liu, Gianluca Lagnese +9
In the context of quantum electrodynamics, the decay of false vacuum leads to the production of electron-positron pair, a phenomenon known as the Schwinger effect. In practical exp…
String-Breaking Dynamics in Quantum Adiabatic and Diabatic Processes
Federica Maria Surace, Alessio Lerose, Or Katz +10
Confinement prohibits isolation of color charges, e.g., quarks, in nature via a process called string breaking: the separation of two charges results in an increase in the energy o…
Observation of string-breaking dynamics in a quantum simulator
Arinjoy De, Alessio Lerose, De Luo +10
Spontaneous particle-pair formation is a fundamental phenomenon in nature. It can, for example, appear when the potential energy between two particles increases with separation, as…
Finite-size generators for weak integrability breaking perturbations in the Heisenberg chain
Sara Vanovac, Federica Maria Surace, Olexei Motrunich
An integrable model perturbed by special ''weak integrability-breaking'' perturbations thermalizes at timescales much longer than predicted by Fermi's golden rule. Recently, a syst…
Simulating Meson Scattering on Spin Quantum Simulators
Elizabeth R. Bennewitz, Brayden Ware, Alexander Schuckert +11
Studying high-energy collisions of composite particles, such as hadrons and nuclei, is an outstanding goal for quantum simulators. However, preparation of hadronic wave packets has…
Unraveling PXP Many-Body Scars through Floquet Dynamics
Giuliano Giudici, Federica Maria Surace, Hannes Pichler
Quantum scars are special eigenstates of many-body systems that evade thermalization. They were first discovered in the PXP model, a well-known effective description of Rydberg ato…
Scalable, ab initio protocol for quantum simulating SU()U(1) Lattice Gauge Theories

We propose a protocol for the scalable quantum simulation of SU()U(1) lattice gauge theories with alkaline-earth like atoms in optical lattices in both one- and two-dime…
Detecting a long lived false vacuum with quantum quenches
Gianluca Lagnese, Federica Maria Surace, Sid Morampudi +1
Distinguishing whether a system supports alternate low-energy (locally stable) states -- stable (true vacuum) versus metastable (false vacuum) -- by direct observation can be diffi…
Robustness and eventual slow decay of bound states of interacting microwave photons in the Google Quantum AI experiment
Federica Maria Surace, Olexei Motrunich
Integrable models are characterized by the existence of stable excitations that can propagate indefinitely without decaying. This includes multi-magnon bound states in the celebrat…
Weak integrability breaking perturbations of integrable models
Federica Maria Surace, Olexei Motrunich
A quantum integrable system slightly perturbed away from integrability is typically expected to thermalize on timescales of order , where is the perturbation stre…

Recent atomic physics experiments and numerical works have reported complementary signatures of the emergence of a topological quantum spin liquid in models with blockade interacti…
Trimer states with topological order in Rydberg atom arrays
Giacomo Giudice, Federica Maria Surace, Hannes Pichler +1
Trimers are defined as two adjacent edges on a graph. We study the quantum states obtained as equal-weight superpositions of all trimer coverings of a lattice, with the constraint…
