Constructive interference at the edge of quantum ergodic dynamics
Dmitry A. Abanin, Rajeev Acharya, Laleh Aghababaie-Beni +262
Quantum observables in the form of few-point correlators are the key to characterizing the dynamics of quantum many-body systems. In dynamics with fast entanglement generation, qua…

Stability of a quantum skyrmion: projective measurements and the quantum Zeno effect
Fabio Salvati, Mikhail I. Katsnelson, Andrey A. Bagrov +1
Magnetic skyrmions are vortex-like quasiparticles characterized by long lifetime and remarkable topological properties. That makes them a promising candidate for the role of inform…

Implementing scalable matrix-vector products for the exact diagonalization methods in quantum many-body physics
Tom Westerhout, Bradford L. Chamberlain
Exact diagonalization is a well-established method for simulating small quantum systems. Its applicability is limited by the exponential growth of the so-called Hamiltonian matrix…
