Quantum Many-Body Scar States with Emergent Kinetic Constraints and Finite-Entanglement Revivals
Thomas Iadecola, Michael Schecter
We construct a set of exact, highly excited eigenstates for a nonintegrable spin-1/2 model in one dimension that is relevant to experiments on Rydberg atoms in the antiblockade reg…
Nematic Bond Theory of Heisenberg Helimagnets
Michael Schecter, Olav. F. Syljuåsen, J. Paaske
We study classical two-dimensional frustrated Heisenberg models with generically incommensurate groundstates. A new theory for the spin-nematic "order by disorder" transition is de…
Composite Topological Excitations in Ferromagnet-Superconductor Heterostructures
Kjetil M. D. Hals, Michael Schecter, Mark S. Rudner
We investigate the formation of a new type of composite topological excitation -- the skyrmion-vortex pair (SVP) -- in hybrid systems consisting of coupled ferromagnetic and superc…
Phonon-mediated Casimir interaction between mobile impurities in one-dimensional quantum liquids
Michael Schecter, Alex Kamenev
Virtual phonons of a quantum liquid scatter off impurities and mediate a long-range interaction, analogous to the Casimir effect. In one dimension the effect is universal and the i…
Feasibility Study of 3D-Printed Micro Junction Array for Ion Trap Quantum Processor
Kento Taniguchi, Ke Sun, Shuqi Xu +6
We introduce an ion trap platform based on a 3D-printed micro-junction array, designed to implement quantum charge-coupled device (QCCD) architectures for large-scale quantum infor…
Spin-lattice order in one-dimensional conductors: beyond the RKKY effect
Michael Schecter, Mark S. Rudner, Karsten Flensberg
We investigate magnetic order in a lattice of classical spins coupled to an isotropic gas of one-dimensional (1d) conduction electrons via local exchange interactions. The frequent…
Dynamics and Bloch oscillations of mobile impurities in one-dimensional quantum liquids
Michael Schecter, Dimitri Gangardt, Alex Kamenev
We study dynamics of a mobile impurity moving in a one-dimensional quantum liquid. Such an impurity induces a strong non-linear depletion of the liquid around it. The dispersion re…
Critical velocity of a mobile impurity in one-dimensional quantum liquids
Michael Schecter, Alex Kamenev, Dimitri Gangardt +1
We study the notion of superfluid critical velocity in one spatial dimension. It is shown that for heavy impurities with mass exceeding a critical mass , the disp…
Quantum Many-Body Scars and Space-Time Crystalline Order from Magnon Condensation
Thomas Iadecola, Michael Schecter, Shenglong Xu
We study the eigenstate properties of a nonintegrable spin chain that was recently realized experimentally in a Rydberg-atom quantum simulator. In the experiment, long-lived cohere…
Interplay between Magnetic and Vestigial Nematic Orders in the Layered - Classical Heisenberg Model
Olav F. Syljuåsen, Jens Paaske, Michael Schecter
We study the layered - classical Heisenberg model on the square lattice using a self-consistent bond theory. We derive the phase diagram for fixed as a function of…
Many-Body Spectral Reflection Symmetry and Protected Infinite-Temperature Degeneracy
Michael Schecter, Thomas Iadecola
Protected zero modes in quantum physics traditionally arise in the context of ground states of many-body Hamiltonians. Here we study the case where zero modes exist in the center o…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Quantum impurities: from mobile Josephson junctions to depletons
Michael Schecter, Dimitri M. Gangardt, Alex Kamenev
We overview the main features of mobile impurities moving in one-dimensional superfluid backgrounds by modeling it as a mobile Josephson junction, which leads naturally to the peri…
The computational power of random quantum circuits in arbitrary geometries
Matthew DeCross, Reza Haghshenas, Minzhao Liu +49
Empirical evidence for a gap between the computational powers of classical and quantum computers has been provided by experiments that sample the output distributions of two-dimens…
Quantum Inverse Freezing and Mirror-Glass Order
Thomas Iadecola, Michael Schecter
It is well-known that spontaneous symmetry breaking in one spatial dimension is thermodynamically forbidden at finite energy density. Here we show that mirror-symmetric disorder in…
Configuration-Controlled Many-Body Localization and the Mobility Emulsion
Michael Schecter, Thomas Iadecola, Sankar Das Sarma
We uncover a new non-ergodic phase, distinct from the many-body localized (MBL) phase, in a disordered two-leg ladder of interacting hardcore bosons. The dynamics of this emergent…
Cooper Pair Induced Frustration and Nematicity of Two-Dimensional Magnetic Adatom Lattices
Michael Schecter, Olav F. Syljuåsen, Jens Paaske
We propose utilizing the Cooper pair to induce magnetic frustration in systems of two-dimensional (2D) magnetic adatom lattices on s-wave superconducting surfaces. The competition…
Comment on "Kinetic theory for a mobile impurity in a degenerate Tonks-Girardeau gas"
Michael Schecter, Alex Kamenev, Dimitri M. Gangardt
In a recent paper, arxiv:1402.6362, Gamayun, Lychkovskiy, and Cheianov studied the dynamics of a mobile impurity embedded into a one-dimensional Tonks-Girardeau gas of strongly int…
Forming doublons by a quantum quench
Michael Schecter, Alex Kamenev
Repulsive interactions between particles on a lattice may lead to bound states, so called doublons. Such states may be created by dynamically tuning the interaction strength, e.g.…
Weak Ergodicity Breaking and Quantum Many-Body Scars in Spin-1 XY Magnets
Michael Schecter, Thomas Iadecola
We study the spin-1 XY model on a hypercubic lattice in dimensions and show that this well-known nonintegrable model hosts an extensive set of anomalous finite-energy-density e…
