Composite helical edges from Abelian fractional topological insulators

Yang-Zhi Chou and Sankar Das Sarma

Phys. Rev. B 110, 155117 (2024) - Published 9 October, 2024

The authors investigate here composite (1+1/n) Abelian helical edge states with the n=2 case, pertinent to recent twisted MoTe2 experiments. The authors construct low-temperature phase diagrams with weak Rashba spin-orbit coupling and calculate edge-state conductance for each phase. The authors further explore the response to an in-plane magnetic field and predict a field-driven phase with 1ne2h edge-state conductance, offering concrete, testable predictions.

Pairing interaction from three-dimensional acoustic plasmon demon modes in Sr2RuO4

Young Woo Choi, Jisoon Ihm, and Marvin L. Cohen

Phys. Rev. B 110, 155127 (2024) - Published 15 October, 2024

Sixty seven years after Pines’ prediction, the “demon” mode – a three-dimensional acoustic plasmon – has been experimentally observed in the unconventional superconductor Sr2RuO4. This low-energy, charge-neutral excitation could play an important role in the superconducting pairing interaction. The authors calculate here how the demon mode affects the dynamical screened Coulomb interaction and the Coulomb kernel in Sr2RuO4. Their findings reveal that the demon mode reduces Coulomb repulsion between electrons, favorable for anisotropic superconductivity. This also suggests that other materials exhibiting demon modes might experience reduced Coulomb repulsion, potentially leading to enhanced superconductivity.

(3+1)-dimensional path integral state sums on curved U(1) bundles and U(1) anomalies of (2+1)-dimensional topological phases

Ryohei Kobayashi and Maissam Barkeshli

Phys. Rev. B 110, 155140 (2024) - Published 17 October, 2024

The authors construct here a lattice path integral for a (3+1)D topological phase with U(1) symmetry, realizing (2+1)D topological order on its boundary. The U(1) background gauge field can possibly have a nontrivial Chern number. This allows the derivation of various formulas for anomalies of topological order involving U(1) symmetry, and leads to Walker-Wang construction of a topological insulator and superconductor. Mathematically, they correspond to new combinatorial state sums for invariants of topologically nontrivial, curved U(1) bundles over 4-manifolds, including spinc, pinc structures.

Projective fixed points for non-Fermi liquids: A case study of the Ising-nematic quantum critical metal

Shubham Kukreja, Afshin Besharat, and Sung-Sik Lee

Phys. Rev. B 110, 155142 (2024) - Published 18 October, 2024

Fixed points of the renormalization group flow play a crucial role in classifying phases of matter. In metals, these fixed points are defined only projectively due to the indefinitely increasing Fermi momentum under scale transformations. Here, the authors study the physical implications of the projective nature of metallic fixed points and chart the space of projective fixed points for Ising-nematic quantum critical metals. Their universality classes are characterized by a nontunable universal forward interaction and intrinsic superconducting fluctuations.

Thermal crossover from a Chern insulator to a fractional Chern insulator in pentalayer graphene

Sankar Das Sarma and Ming Xie

Phys. Rev. B 110, 155148 (2024) - Published 22 October, 2024

A recent experiment in pentalayer graphene/hBN moiré superlattices uncovered a surprising new phase, with integer quantization at fractional fillings, emerging at lower temperatures than the previously observed FQAHE states. Through theoretical analysis of the transport data, the authors establish here that this low-temperature phase is likely a disorder-induced localized insulating phase, and that the transition between this phase and the higher temperature FQAHE phase is a crossover phenomenon driven by the competition between interaction and disorder energy scales.

Unconventional discontinuous transitions in a two-dimensional system with spin and valley degrees of freedom

Zachary M. Raines, Leonid I. Glazman, and Andrey V. Chubukov

Phys. Rev. B 110, 155402 (2024) - Published 1 October, 2024

Many interesting quasi-two-dimensional materials host effectively conserved low-energy spin and valley isospin degrees of freedom. In a number of these systems isospin symmetry is broken by a cascade of transitions into fractional metal states, where some number of isospin species are spontaneously depleted. Here, the authors study itinerant isospin symmetry breaking transitions in multivalley system, showing that for a range of parameters there is naturally such a cascade of strongly first-order transitions coinciding with a large enhancement of the associated isospin susceptibilities.

Increased neutron reflectivity and polarization of neutron-optical engineered Fe/B411CTi multilayer optics

A. Zubayer, N. Ghafoor, K. A. Thorarinsdottir, A. Glavic, J. Stahn, G. Nagy, A. Vorobiev, F. Magnus, J. Birch, and F. Eriksson

Phys. Rev. B 110, 155408 (2024) - Published 4 October, 2024

This study explores the use of Fe/11B4CTi multilayers for polarizing neutron optics, with a focus on tuning the scattering length density (SLD). Compared to the conventional Fe/Si systems, Fe/11B4CTi multilayers demonstrate enhanced reflectivity and polarization due to reduced interface width and optimized SLD matching and contrast. By adjusting the ratio of 11B4C and Ti, a wide range of SLD contrasts can be achieved, allowing for fine-tuning of polarization. These findings highlight the potential of SLD-tuned multilayers for advancing thin-film neutron optics applications.

Intrinsic process for upconversion photoluminescence via K-momentum–phonon coupling in carbon nanotubes

Daichi Kozawa, Shun Fujii, and Yuichiro K. Kato

Phys. Rev. B 110, 155418 (2024) - Published 10 October, 2024

Carbon nanotubes exhibit efficient upconversion photoluminescence, which has been thought to arise from extrinsic effects such as defects. By using single nanotube spectroscopy on defect-free, air-suspended carbon nanotubes, the authors demonstrate here that upconversion readily occurs through an intrinsic process. Sidebands in the upconversion photoluminescence excitation spectra are assigned to K-momentum phonon modes, explaining the mechanism of upconversion. With efficient upconversion, large energy gain, and near-unity radiative quantum efficiency, these pristine nanotubes offer a promising platform for exploring optothermal effects.

Resonance energy transfer in the presence of a spherical cavity and dispersive substrate

Elliot K. Beutler, Jon P. Camden, and David J. Masiello

Phys. Rev. B 110, 155435 (2024) - Published 24 October, 2024

Resonator cavities are known to influence the rate of energy exchange between nearby emitters due to their local modifications of the electromagnetic density of states. The emitters’ positions, orientations, and detuning relative to each other and to their cavity environment all affect the degree to which energy transfer is enhanced or suppressed. However, the role of the underlying substrate sometimes used to support the cavity is often underestimated. Here, the authors model the interaction between a pair of emitters in the presence of a composite spherical cavity-substrate system and demonstrate that the resonant features of the substrate may dramatically influence the resulting density of states and energy transfer rate.

Rydberg series of intralayer K-excitons in WSe2 multilayers

Piotr Kapuściński, Artur O. Slobodeniuk, Alex Delhomme, Clément Faugeras, Magdalena Grzeszczyk, Karol Nogajewski, Kenji Watanabe, Takashi Taniguchi, and Marek Potemski

Phys. Rev. B 110, 155439 (2024) - Published 30 October, 2024

Here, the authors combine magnetoreflectance experiments with theoretical modeling based on the kp approach to explore the origin and properties of intravalley excitons in WSe2 bi-, tri-, and quadlayers. The reflectance spectra display rich excitonic series across all thicknesses. By comparing magnetoreflectance data with theoretical predictions, the authors reveal that excitonic resonances in trilayers arise from two distinct Rydberg series, quadlayers exhibit four such series, and bilayers feature a single Rydberg series akin to that of monolayers.

This study explores the use of Fe/11B4CTi multilayers for polarizing neutron optics, with a focus on tuning the scattering length density (SLD). Compared to the conventional Fe/Si systems, Fe/11B4CTi multilayers demonstrate enhanced reflectivity and polarization due to reduced interface width and optimized SLD matching and contrast. By adjusting the ratio of 11B4C and Ti, a wide range of SLD contrasts can be achieved, allowing for fine-tuning of polarization. These findings highlight the potential of SLD-tuned multilayers for advancing thin-film neutron optics applications.

Intrinsic process for upconversion photoluminescence via K-momentum–phonon coupling in carbon nanotubes

Phys. Rev. B 110, 155418 (2024) - Published 10 October, 2024

Carbon nanotubes exhibit efficient upconversion photoluminescence, which has been thought to arise from extrinsic effects such as defects. By using single nanotube spectroscopy on defect-free, air-suspended carbon nanotubes, the authors demonstrate here that upconversion readily occurs through an intrinsic process. Sidebands in the upconversion photoluminescence excitation spectra are assigned to K-momentum phonon modes, explaining the mechanism of upconversion. With efficient upconversion, large energy gain, and near-unity radiative quantum efficiency, these pristine nanotubes offer a promising platform for exploring optothermal effects.

Resonator cavities are known to influence the rate of energy exchange between nearby emitters due to their local modifications of the electromagnetic density of states. The emitters’ positions, orientations, and detuning relative to each other and to their cavity environment all affect the degree to which energy transfer is enhanced or suppressed. However, the role of the underlying substrate sometimes used to support the cavity is often underestimated. Here, the authors model the interaction between a pair of emitters in the presence of a composite spherical cavity-substrate system and demonstrate that the resonant features of the substrate may dramatically influence the resulting density of states and energy transfer rate.

Here, the authors combine magnetoreflectance experiments with theoretical modeling based on the kp approach to explore the origin and properties of intravalley excitons in WSe2 bi-, tri-, and quadlayers. The reflectance spectra display rich excitonic series across all thicknesses. By comparing magnetoreflectance data with theoretical predictions, the authors reveal that excitonic resonances in trilayers arise from two distinct Rydberg series, quadlayers exhibit four such series, and bilayers feature a single Rydberg series akin to that of monolayers.
