Author(s): Castelnovo, Claudio; Dykman, Mark I; Smelyanskiy, Vadim N; Moessner, Roderich; Pryadko, Leonid P | Abstract: Motivated by the existence of mobile low-energy excitations like domain walls in one dimension or gauge-charged fractionalized particles in higher dimensions, we compare quantum dynamics in the presence of weak Markovian dephasing for a particle hopping on a chain and for an Ising domain wall whose motion leaves behind a string of flipped spins. Exact solutions show that the… 



Su-Schrieffer-Heeger model applied to chains of finite length.

The exact expression for the sound velocity renormalization due to the p-electron-phonon coupling is derived, arriving at earlier heuristically, from the Su-Schrieffer-Heeger Hamiltonian with a boundary term added.

Observation of the topological soliton state in the Su–Schrieffer–Heeger model

The Su–Schrieffer–Heeger model, which captures the most striking transport properties of the conductive organic polymer trans-polyacetylene, provides perhaps the most basic model system supporting topological excitations, and quantum simulation of this model and observation of the localized topological soliton state are reported on.

The CuO/sub 2/ planes in the high-temperature superconductors are described by a two-dimensional Hubbard model and a pair of holes, which naively should be quite mobile, are found to be extremely heavy due to a previously unappreciated frustration effect that impedes their motion.

Monopole and Dirac string Dynamics in Spin Ice

Magnetic monopoles have eluded experimental detection since their prediction nearly a century ago by Dirac. Recently it has been shown that classical analogues of these enigmatic particles occur as

Quantum Criticality in an Ising Chain: Experimental Evidence for Emergent E8 Symmetry

A long-predicted hidden symmetry in spin ordering has been observed experimentally at temperatures near absolute zero and is in quantitative agreement with the so-called golden ratio predicted for the first two meson particles of the E8 spectrum.

Conduction in non-crystalline systems. X. Mobility and percolation edges

Abstract A distinction is made between a mobility edge, which is a quantum-mechanical phenomenon predicted for non-crystalline conductors, and a percolation edge which occurs in classical theory as a

Observation of discrete time-crystalline order in a disordered dipolar many-body system

This work observes long-lived temporal correlations, experimentally identifies the phase boundary and finds that the temporal order is protected by strong interactions, which opens the door to exploring dynamical phases of matter and controlling interacting, disordered many-body systems.

Possibility of quasiparticle behaviour in the strongly correlated Hubbard model

The author calculates an exact expression for the Green function of a single hole in a Neel background, for finite Ising interaction Jz identical to 4t2/U where t is the hopping (overlap) integral in

Spin Ice, Fractionalization, and Topological Order

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 are highly unusual magnets that epitomize a set of concepts of great interest in modern condensed matter physics: Their low-energy physics exhibits an

Quantum kinetics of an open system in the presence of periodic refocusing fields

We consider quantum kinetics of an open quantum system in the presence of periodic fields designed to suppress the internal evolution and shield the system from a generic low-frequency environment
