HIGHLIGHTED ARTICLES

Symmetric improved estimators for multipoint vertex functions

Jae-Mo Lihm, Johannes Halbinger, Jeongmin Shim, Jan von Delft, Fabian B. Kugler, and Seung-Sup B. Lee

Phys. Rev. B 109, 125138 (2024) - Published 21 March, 2024

The authors develop here a new representation of two-particle vertices, the effective interaction between quantum particles in a many-body environment. This yields numerical results with much higher accuracy and robustness than previously possible. By avoiding error-prone inversion, their “symmetric improved estimators” successfully pass stringent precision tests in both the real- and imaginary-frequency frameworks of quantum field theory. This scheme allows field-theoretic methods for strongly correlated electrons to expand into the real-frequency direction.

Strong-coupling topological states and phase transitions in helical trilayer graphene

Yves H. Kwan, Patrick J. Ledwith, Chiu Fan Bowen Lo, and Trithep Devakul

Phys. Rev. B 109, 125141 (2024) - Published 21 March, 2024

Helical trilayer graphene is a new experimentally accessible magic-angle graphene heterostructure with nontrivial physics at both the moiré and supermoiré scale. The authors’ theoretical analysis reveals a plethora of topological strong-coupling Chern insulators at all integer moiré fillings. Crucially, the band renormalization that plagues previous moiré graphene systems is significantly suppressed, ensuring the validity of the strong-coupling perspective and opening the path to fractionalized phases. At experimentally accessible displacement fields, the authors find continuous topological transitions to more complex orders. Their results establish helical trilayer graphene as a promising platform for tunable strongly interacting topological phases.

Chiral spin liquid and quantum phase diagram of spin-12 J1J2Jχ model on the square lattice

Xiao-Tian Zhang, Yixuan Huang, Han-Qing Wu, D. N. Sheng, and Shou-Shu Gong

Phys. Rev. B 109, 125146 (2024) - Published 26 March, 2024

A chiral spin liquid (CSL) is an analog of the fractional quantum Hall state in spin systems. Recently, an interesting topic has been the coexistence of CSL and magnetic order, which is beyond the conventional understanding of the spin liquid. Here, the authors examine possible phase coexistence in the spin-½ square-lattice J1-J2-Jχ model, by using unbiased density matrix renormalization group calculations. The numerical data identify the CSL but find no evidence for the phase coexistence that was conjectured by mean-field calculations.

Dynamics of vacancy-induced modes in the non-Abelian Kitaev spin liquid

Wen-Han Kao, Gábor B. Halász, and Natalia B. Perkins

Phys. Rev. B 109, 125150 (2024) - Published 29 March, 2024

Identification of quantum spin liquids faces two main challenges: the absence of local magnetic ordering and the inevitable presence of disorder. Analyzing the dynamical response of the site-diluted Kitaev spin liquid, the authors reveal here distinctive Majorana features, including a quasi-zero-frequency peak, explained by a local hybridization model of defect-induced Majorana modes. These findings, highlighting the nontrivial interplay between disorder and spin fractionalization, suggest the potential detection of spin-liquid phases in candidate materials by using scanning tunneling microscopy (STM).

Absence of Weyl nodes in EuCd2As2 revealed by the carrier density dependence of the anomalous Hall effect

Yue Shi, Zhaoyu Liu, Logan A. Burnett, Seokhyeong Lee, Chaowei Hu, Qianni Jiang, Jiaqi Cai, Xiaodong Xu, Mo Li, Cheng-Chien Chen, and Jiun-Haw Chu

Phys. Rev. B 109, 125202 (2024) - Published 26 March, 2024

EuCd2As2 has been widely considered as a leading candidate for the ideal Weyl semimetal. However, a recent study challenged this view by discovering a substantial band gap in this system. Here, the authors successfully synthesize highly insulating EuCd2As2. It reveals a decrease of the anomalous Hall conductivity (AHC) by orders of magnitude as the carrier density decreases, contradicting the expected behavior of intrinsic AHC generated by the Weyl points. The results suggest that EuCd2As2 is a magnetic semiconductor rather than a Weyl semimetal.

Moiré fractals in twisted graphene layers

Deepanshu Aggarwal, Rohit Narula, and Sankalpa Ghosh

Phys. Rev. B 109, 125302 (2024) - Published 1 March, 2024

Fractals are ubiquitous in nature. When two-dimensional crystals such as graphene or h-BN are multiply stacked and then twisted by a specific angle, the resulting super-moiré pattern exhibits electronic fractality. The authors call these novel structures “moiré fractals”. They derive a formula that relates their fractal dimension to the number of electronic bands in a given energy window. Such a number of bands fundamentally constrains charge and heat transport, thus providing a powerful tool for engineering designer quantum materials.

Occupancy-driven Zeeman suppression and inversion in trapped polariton condensates

Krzysztof Sawicki, Dmitriy Dovzhenko, Yuan Wang, Tamsin Cookson, Helgi Sigurðsson, and Pavlos G. Lagoudakis

Phys. Rev. B 109, 125307 (2024) - Published 26 March, 2024

Extremely high coherence time and, thus, ultranarrow spectral linewidths make it possible to resolve magnetically induced µeV fine-energy shifts in trapped exciton-polariton condensates. The continuous control over the polariton confinement enable the authors here to explore two operation regimes: (1) the full parametric screening of the Zeeman splitting and (2) the Zeeman inversion regime. The transition from one range to the other occurs by adjusting the size of the optical trap, which controls the strength of the polariton-polariton and polariton-exciton reservoir interactions.

Experimental demonstration of a two-dimensional hole gas in a GaN/AlGaN/GaN based heterostructure by optical spectroscopy

Loïc Méchin, François Médard, Joël Leymarie, Sophie Bouchoule, Jean-Yves Duboz, Blandine Alloing, Jesús Zuñiga-Pérez, and Pierre Disseix

Phys. Rev. B 109, 125401 (2024) - Published 1 March, 2024

Optical spectroscopy techniques, including time-resolved and intensity-dependent photoluminescence, are employed here to optically demonstrate, for the first time, the presence of a buried two-dimensional hole gas (2DHG) in a nitride-based heterostructure. The characteristic spectral and temporal features of this recombination highlight the asymmetric electric field distribution on either side of the 2DHG. The effects of this electric field are discussed, particularly regarding their implications for optical recombination mechanisms within the heterostructure.

Propagation of focused scalar and vector vortex beams in anisotropic media: A semianalytical approach

Vittorio Aita, Mykyta Shevchenko, Francisco J. Rodríguez-Fortuño, and Anatoly V. Zayats

Phys. Rev. B 109, 125433 (2024) - Published 29 March, 2024

Presented in this work is a versatile model designed for simulating the propagation of focused scalar and vector beams through three-layered systems, addressing a wide range of beams and materials. The former are described within the Laguerre-Gauss basis, while the latter encompass dispersive and lossy materials - whether isotropic or uniaxial - enabling the investigation of elliptic, hyperbolic, and epsilon-near-zero dispersion regimes. The developed model has been released as an open-source software package for wider accessibility.

Coexistence of topological and normal insulating phases in electro-optically tuned InAs/GaSb bilayer quantum wells

M. Meyer, T. Fähndrich, S. Schmid, A. Wolf, S. S. Krishtopenko, B. Jouault, G. Bastard, F. Teppe, F. Hartmann, and S. Höfling

Phys. Rev. B 109, L121303 (2024) - Published 27 March, 2024

Topological insulators (TIs) based on InAs/GaSb bilayer quantum wells are appealing due to the electric field tuning between topological and normal insulating (NI) phases. Here, the authors report on the coexistence of NI and TI phases in electro-optically tuned InAs/GaSb bilayer quantum wells and helical edge channels in the bulk of the sample. These findings pave the way to the manipulation and utilization of helical edge channels by using spatially defined gates (optically or electrically), separating them from the physical edges.

The authors develop here a new representation of two-particle vertices, the effective interaction between quantum particles in a many-body environment. This yields numerical results with much higher accuracy and robustness than previously possible. By avoiding error-prone inversion, their “symmetric improved estimators” successfully pass stringent precision tests in both the real- and imaginary-frequency frameworks of quantum field theory. This scheme allows field-theoretic methods for strongly correlated electrons to expand into the real-frequency direction.

The authors’ theoretical analysis reveals a plethora of topological strong-coupling Chern insulators at all integer moiré fillings. Crucially, the band renormalization that plagues previous moiré graphene systems is significantly suppressed, ensuring the validity of the strong-coupling perspective and opening the path to fractionalized phases. At experimentally accessible displacement fields, the authors find continuous topological transitions to more complex orders. Their results establish helical trilayer graphene as a promising platform for tunable strongly interacting topological phases.

A chiral spin liquid (CSL) is an analog of the fractional quantum Hall state in spin systems. Recently, an interesting topic has been the coexistence of CSL and magnetic order, which is beyond the conventional understanding of the spin liquid. Here, the authors examine possible phase coexistence in the spin-½ square-lattice J1-J2-Jχ model, by using unbiased density matrix renormalization group calculations. The numerical data identify the CSL but find no evidence for the phase coexistence that was conjectured by mean-field calculations.

Phys. Rev. B 109, 125150 (2024) - Published 29 March, 2024

Identification of quantum spin liquids faces two main challenges: the absence of local magnetic ordering and the inevitable presence of disorder. Analyzing the dynamical response of the site-diluted Kitaev spin liquid, the authors reveal here distinctive Majorana features, including a quasi-zero-frequency peak, explained by a local hybridization model of defect-induced Majorana modes. These findings, highlighting the nontrivial interplay between disorder and spin fractionalization, suggest the potential detection of spin-liquid phases in candidate materials by using scanning tunneling microscopy (STM).

EuCd2As2 has been widely considered as a leading candidate for the ideal Weyl semimetal. However, a recent study challenged this view by discovering a substantial band gap in this system. Here, the authors successfully synthesize highly insulating EuCd2As2. It reveals a decrease of the anomalous Hall conductivity (AHC) by orders of magnitude as the carrier density decreases, contradicting the expected behavior of intrinsic AHC generated by the Weyl points. The results suggest that EuCd2As2 is a magnetic semiconductor rather than a Weyl semimetal.

Moiré fractals in twisted graphene layers

Fractals are ubiquitous in nature. When two-dimensional crystals such as graphene or h-BN are multiply stacked and then twisted by a specific angle, the resulting super-moiré pattern exhibits electronic fractality. The authors call these novel structures “moiré fractals”. They derive a formula that relates their fractal dimension to the number of electronic bands in a given energy window. Such a number of bands fundamentally constrains charge and heat transport, thus providing a powerful tool for engineering designer quantum materials.

Extremely high coherence time and, thus, ultranarrow spectral linewidths make it possible to resolve magnetically induced µeV fine-energy shifts in trapped exciton-polariton condensates. The continuous control over the polariton confinement enable the authors here to explore two operation regimes: (1) the full parametric screening of the Zeeman splitting and (2) the Zeeman inversion regime. The transition from one range to the other occurs by adjusting the size of the optical trap, which controls the strength of the polariton-polariton and polariton-exciton reservoir interactions.

Optical spectroscopy techniques, including time-resolved and intensity-dependent photoluminescence, are employed here to optically demonstrate, for the first time, the presence of a buried two-dimensional hole gas (2DHG) in a nitride-based heterostructure. The characteristic spectral and temporal features of this recombination highlight the asymmetric electric field distribution on either side of the 2DHG. The effects of this electric field are discussed, particularly regarding their implications for optical recombination mechanisms within the heterostructure.

Presented in this work is a versatile model designed for simulating the propagation of focused scalar and vector beams through three-layered systems, addressing a wide range of beams and materials. The former are described within the Laguerre-Gauss basis, while the latter encompass dispersive and lossy materials - whether isotropic or uniaxial - enabling the investigation of elliptic, hyperbolic, and epsilon-near-zero dispersion regimes. The developed model has been released as an open-source software package for wider accessibility.
