Challenges to observation of many-body localization

Piotr Sierant and Jakub Zakrzewski

Phys. Rev. B 105, 224203 (2022) - Published 14 June, 2022

Many-body localization (MBL) freezes the dynamics of a disordered quantum interacting system, inhibiting thermalization and resulting in a persistent memory of the initial state. Here, with the help of extensive numerical simulations, the authors find slow decay of the imbalance, a quantity often employed in experimental studies of MBL, even though the disorder strength considerably exceeds the current estimates of the position of the MBL transition. This suggests a slow approach to thermal equilibrium and identifies challenges for unequivocal numerical and experimental demonstrations of MBL.

Cumulant methods for electron-phonon problems. I. Perturbative expansions

Paul J. Robinson, Ian S. Dunn, and David R. Reichman

Phys. Rev. B 105, 224304 (2022) - Published 7 June, 2022

The cumulant expansion has become a popular tool for describing the dynamics of electrons coupled to phonons. Here, using the Holstein model, the authors study the behavior of low-order cumulants, and present a self-consistent formulation of the cumulant expansion. They find that the second-order cumulant performs well at zero electronic momentum or high temperature, and the fourth order cumulant becomes pathological, preventing its general application. The self-consistent formulation greatly improves the spectra by including non-perturbative effects, but also presents pathologies. These results have implications for calculations of transport properties and ab initio systems.

Beyond the freshman's dream: Classical fractal spin liquids from matrix cellular automata in three-dimensional lattice models

Sounak Biswas, Yves H. Kwan, and S. A. Parameswaran

Phys. Rev. B 105, 224410 (2022) - Published 21 June, 2022

The Newman-Moore model on the 2D triangular lattice is a classic example of a statistical mechanical model with immobile fractal excitations: fractons. These result in kinetic constraints leading to glassy behavior. Here, the authors generalize this construction to two 3D lattices, trillium and hyperhyperkagome. While these models exhibit a similar phenomenology, the authors show that the underlying fractons have a richer structure and are intimately connected to the matrix cellular automata that describe the manifold of ground states.

Band filling effects on the emergence of magnetic skyrmions: Pd/Fe and Pd/Co bilayers on Ir(111)

I. P. Miranda, A. B. Klautau, A. Bergman, and H. M. Petrilli

Phys. Rev. B 105, 224413 (2022) - Published 21 June, 2022

Structurally similar transition metal systems can exhibit very different magnetic properties. An instructive example is the widely studied Pd/Fe/Ir(111) multilayer, which shows a spin-spiral ground state, while Pd/Co/Ir(111) presents a ferromagnetic (single-domain) ground state. Here, the authors analyze the origin of this difference combining ab initio and atomistic spin-dynamics calculations, demonstrating that the distinct behaviors can be explained by a simple rigid-band-like model. This analysis highlights the possibility of tuning topological magnetic structures by alloying and/or external agents, e.g., electric fields.

Nonequilibrium quasistationary spin disordered state in αRuCl3

R. B. Versteeg, A. Chiocchetta, F. Sekiguchi, A. Sahasrabudhe, J. Wagner, A. I. R. Aldea, K. Budzinauskas, Zhe Wang, V. Tsurkan, A. Loidl, D. I. Khomskii, S. Diehl, and P. H. M. van Loosdrecht

Phys. Rev. B 105, 224428 (2022) - Published 30 June, 2022

The authors use optical excitation as a way to alter the magnetic free energy landscape and the resulting phase diagram of the frustrated honeycomb magnet α-RuCl3. They time-track experimentally the magneto-optical response from the α-RuCl3’s zigzag-ordered ground state after photoexcitation and they reproduce the observed dynamics within a Ginzburg-Landau model. A quasistationary spin disordered state is induced above a critical photoexcitation density, suggesting a new route to reach a nontrivial spin disordered state in Kitaev-like magnets such as α-RuCl3.

Symmetry constraints on superconductivity in twisted bilayer graphene: Fractional vortices, 4e condensates, or nonunitary pairing

Eslam Khalaf, Patrick Ledwith, and Ashvin Vishwanath

Phys. Rev. B 105, 224508 (2022) - Published 8 June, 2022

Twisted bilayer graphene has recently emerged as an exciting platform to study interaction-driven phases. Among these, superconductivity has received intense theoretical effort to understand its underlying mechanism. In this work, the authors establish general symmetry constraints on the nature of superconductivity in twisted bilayer graphene that are independent of its mechanism. These constraints are sufficient to limit the nature of superconductivity to one of three unconventional possibilities: nonunitary pairing, unitary pairing with fractional vortices, or higher-charge condensates. They identify parameter regimes where each possibility is likely to occur.

The authors use optical excitation as a way to alter the magnetic free energy landscape and the resulting phase diagram of the frustrated honeycomb magnet α-RuCl3. They time-track experimentally the magneto-optical response from the α-RuCl3’s zigzag-ordered ground state after photoexcitation and they reproduce the observed dynamics within a Ginzburg-Landau model. A quasistationary spin disordered state is induced above a critical photoexcitation density, suggesting a new route to reach a nontrivial spin disordered state in Kitaev-like magnets such as α-RuCl3.

Symmetry constraints on superconductivity in twisted bilayer graphene: Fractional vortices, 4e condensates, or nonunitary pairing

Phys. Rev. B 105, 224508 (2022) - Published 8 June, 2022

Twisted bilayer graphene has recently emerged as an exciting platform to study interaction-driven phases. Among these, superconductivity has received intense theoretical effort to understand its underlying mechanism. In this work, the authors establish general symmetry constraints on the nature of superconductivity in twisted bilayer graphene that are independent of its mechanism. These constraints are sufficient to limit the nature of superconductivity to one of three unconventional possibilities: nonunitary pairing, unitary pairing with fractional vortices, or higher-charge condensates. They identify parameter regimes where each possibility is likely to occur.
