Entanglement scaling in matrix product state representation of smooth functions and their shallow quantum circuit approximations

Vladyslav Bohun, Illia Lukin, Mykola Luhanko +4

Encoding classical data in a quantum state is a key prerequisite of many quantum algorithms. Recently matrix product state (MPS) methods emerged as the most promising approach for…

Towards realistic symmetry-based completion of previously unseen point clouds

Taras Rumezhak, Oles Dobosevych, Rostyslav Hryniv +3

3D scanning is a complex multistage process that generates a point cloud of an object typically containing damaged parts due to occlusions, reflections, shadows, scanner motion, sp…

ActGAN: Flexible and Efficient One-shot Face Reenactment

Ivan Kosarevych, Marian Petruk, Markian Kostiv +3

This paper introduces ActGAN - a novel end-to-end generative adversarial network (GAN) for one-shot face reenactment. Given two images, the goal is to transfer the facial expressio…

Training Deep Neural Networks by optimizing over nonlocal paths in hyperparameter space

Vlad Pushkarov, Jonathan Efroni, Mykola Maksymenko +1

Hyperparameter optimization is both a practical issue and an interesting theoretical problem in training of deep architectures. Despite many recent advances the most commonly used…

Topology and localization of a periodically driven Kitaev model

I. C. Fulga, M. Maksymenko, M. T. Rieder +2

Periodically driven quantum many-body systems support anomalous topological phases of matter, which cannot be realized by static systems. In many cases, these anomalous phases can…

Persistence of the flat band in a kagome magnet with dipolar interactions

Mykola Maksymenko, Roderich Moessner, Kirill Shtengel

The weathervane modes of the classical Heisenberg antiferromagnet on the kagome lattice constitute possibly the earliest and certainly the most celebrated example of a flat band of…

Dynamics of a Many-Body-Localized System Coupled to a Bath

Mark H Fischer, Mykola Maksymenko, Ehud Altman

Coupling a many-body-localized system to a dissipative bath necessarily leads to delocalization. Here, we investigate the nature of the ensuing relaxation dynamics and the informat…

ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase

M. Ozerov, M. Maksymenko, J. Wosnitza +6

Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…

Scattering matrix invariants of Floquet topological insulators

I. C. Fulga, M. Maksymenko

Similar to static systems, periodically driven systems can host a variety of topologically non-trivial phases. Unlike the case of static Hamiltonians, the topological indices of bu…

Flat-Band Ferromagnetism as a Pauli-Correlated Percolation Problem

M. Maksymenko, A. Honecker, R. Moessner +2

We investigate the location and nature of the para-ferro transition of interacting electrons in dispersionless bands using the example of the Hubbard model on the Tasaki lattice. T…
