About
Anatoli Polkovnikov is a Professor in the Department of Physics and the Division of Materials Science & Engineering at Boston University. He holds a Ph.D. from Yale University, earned in 2003 under the supervision of Subir Sachdev, and an M.S. from St. Petersburg State Polytechnical University obtained in 1998. His research focuses on understanding various properties of interacting many-particle systems, especially those driven away from equilibrium. His areas of interest include strongly correlated systems, the physics of cold atoms and spin systems, and superconductivity. Professor Polkovnikov's work involves the representation of quantum dynamics through classical trajectories, understanding non-equilibrium thermodynamics from microscopics, exploring universal aspects of dissipation during nearly adiabatic evolution, and studying dynamics near phase transitions. His research is closely tied to experiments in cold atom systems, aiming to deepen the understanding of complex quantum phenomena and their applications.

Adiabatic Eigenstate Deformations as a Sensitive Probe for Quantum Chaos
Physical Review X · 2020 · 138 citations
In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective description of the eigenstates of chaotic Hamiltonians through random matrix ensembles and the eigenstate thermalization hypothesis. Standard measures of chaos in quantum many-body systems are level statistics and the spectral form factor. In this work, we show that the norm of the adiabatic gauge potential, the generator o…
Efficient paths for local counterdiabatic driving
Physical review. B./Physical review. B · 2024-07-02 · 17 citations
articleSenior authorLocal counterdiabatic driving (CD) provides a feasible approach for realizing approximate adiabatic or reversible processes like quantum state preparation using only local controls and without demanding excessively long protocol times. However, in many instances getting high accuracy of such CD protocols requires engineering very complicated new controls or pulse sequences. In this work, we describe a systematic method for altering the adiabatic path by adding extra local controls along which pe…
Integrability as an attractor of adiabatic flows
Physical review. B./Physical review. B · 2024-05-21 · 12 citations
articleSenior authorGeneric many-body particle systems typically exhibit chaos and thermalization. Amidst this chaotic landscape there are special systems called integrable, for example, systems of noninteracting particles that are neither chaotic nor thermalizing. Integrable systems usually require a high degree of fine-tuning of the Hamiltonian that defines their dynamics. The authors find that these special systems act as natural geometric attractors of adiabatic flows that follow the directions of fastest relax…
Robust Effective Ground State in a Nonintegrable Floquet Quantum Circuit
Physical Review Letters · 2024-07-17 · 9 citations
articleOpen accessSenior authorAn external periodic (Floquet) drive is believed to bring any initial state to the featureless infinite temperature state in generic nonintegrable isolated quantum many-body systems in the thermodynamic limit, irrespective of the driving frequency Ω. However, numerical or analytical evidence either proving or disproving this hypothesis is very limited and the issue has remained unsettled. Here, we study the initial state dependence of Floquet heating in a nonintegrable kicked Ising chain of leng…
