Interface phases and dynamics in two-dimensional quantum magnets: A "holographic" approach from universality to quantum simulation
Abhishodh Prakash, Jaydev Singh Rao, Siddharth A. Parameswaran +1
We introduce a framework to classify quantum phases, phase transitions, and non-equilibrium dynamics of interfaces separating ordered bulk domains in 2D quantum magnets - equivalen…
Multibath Influence Matrices: Universal Scaling from Real-Time Dynamics
Matan Lotem, Michael Sonner, Valentin Link +2
Diverging timescales are the hallmark of critical dynamics and the bottleneck to their classical and quantum simulation. To tame this, we compress a spacetime tensor network: tempo…
Stark localization of interacting particles
Wojciech De Roeck, Amirali Hannani, Alessio Lerose +1
We consider N interacting quantum particles on a one-dimensional lattice, and subjected to an external linear potential. For N = 1, the corresponding Hamiltonian is explicitly diag…
Temporal entanglement transition in chaotic quantum many-body dynamics
Ilya Vilkoviskiy, Michael Sonner, Qi Camm Huang +3
Temporal entanglement (TE) of an influence matrix (IM) has been proposed as a measure of complexity of simulating dynamics of local observables in a many-body system. Foligno et al…

Using a 36-qubit quantum processor, we demonstrate that, by operating in conjunction with a classical machine learning agent, quantum computers can discover instances of interestin…
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…
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…

Alessio Lerose
Real-time dynamics of the Schwinger model provide an effective description of quark confinement out of equilibrium, routinely employed to model hadronization processes in particle-…

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…

Alessio Lerose, Tommaso Parolini, Rosario Fazio +2
Quantum many-body scars (QMBS) are exceptional energy eigenstates of quantum many-body systems associated with violations of thermalization for special non-equilibrium initial stat…
