Perturbative analysis of quasiperiodic patterning of transmon quantum computers: Enhancement of many-body localization

Evangelos Varvelis and David P. DiVincenzo

Phys. Rev. B 109, 144201 (2024) - Published 10 April, 2024

To be useful for quantum computation, qubits in an array must remain localized – that is, not “dressed” too much by nearby degrees of freedom. This localization has been previously achieved using disorder. But the authors observe here that a more effective route to localization is with a quasiperiodic patterning of the qubit array Hamiltonian. This paper develops two different perturbation approaches to calculate diagnostics for many-body localization in quasiperiodic superconducting transmon arrays. Perturbing in anharmonicity versus perturbing in hopping strength give complementary information.

Topological enhancement of nonnormality in non-Hermitian skin effects

Yusuke O. Nakai, Nobuyuki Okuma, Daichi Nakamura, Kenji Shimomura, and Masatoshi Sato

Phys. Rev. B 109, 144203 (2024) - Published 26 April, 2024

This paper introduces scalar measures that adequately characterize the non-Hermitian skin effects under open boundary condition. Using these measures, the authors reveal that the topological properties of the non-Hermitian skin effect give a macroscopic enhancement of non-normality under open boundary condition. The topological enhancement of non-normality governs the perturbation sensitivity of the spectra and the anomalous time-evolution dynamics intrinsic to non-Hermiticity. They also show that these measures correctly describe the disorder-induced topological phase transitions of the skin effect.

Helimagnetism in the candidate ferroelectric CrI2

John A. Schneeloch, Shunshun Liu, Prasanna V. Balachandran, Qiang Zhang, and Despina Louca

Phys. Rev. B 109, 144403 (2024) - Published 3 April, 2024

Although many other transition metal halides have been magnetically characterized, CrI2, a proposed “sliding ferroelectric”, has been overlooked. Via neutron powder diffraction, the authors report here that a screw-like helimagnetic order develops below 17 K, corresponding to a ~90º spin rotation per Cr ion along the “ribbon chains”. Calculations suggest that, as in the structurally and magnetically similar copper dihalides, the helimagnetism arises due to a sufficiently antiferromagnetic intrachain next-nearest-neighbor coupling.

Near power-law temperature dependence of the superfluid stiffness in strongly disordered superconductors

Anton V. Khvalyuk, Thibault Charpentier, Nicolas Roch, Benjamin Sacépé, and Mikhail V. Feigel'man

Phys. Rev. B 109, 144501 (2024) - Published 1 April, 2024

This paper reports unconventional behavior of the superfluid stiffness Θ(T) in disordered superconductors, such as to amorphous InOx. The authors unveil a remarkable power-law suppression δΘ(T)Tb at TTc, with an exponent b1.6. Through a combination of experiments and theory, they reveal the influence of disorder on this phenomenon, shedding light on the existence of low-energy collective excitations. These findings redefine our understanding of dissipation in inhomogeneous superconductors, with implications for their use in quantum circuits.

Superfluid stiffness within Eliashberg theory: The role of vertex corrections

Zachary M. Raines, Shang-Shun Zhang, and Andrey V. Chubukov

Phys. Rev. B 109, 144505 (2024) - Published 5 April, 2024

The superfluid stiffness Ds(T) is one of the key characteristics of a superconductor, determining the magnetic penetration length and, in two dimensions, the critical temperature. For Galilean invariant systems, it is known that the zero-temperature stiffness takes a universal value DsGal = nm (T=0), while for non-Galilean invariant systems the superfluid stiffness may be suppressed. Here, the authors demonstrate when and how vertex corrections may cancel suppression of the superfluid stiffness at strong coupling.

Thickness-dependent anisotropic superconductivity and charge density wave in ZrTe3 down to the two-dimensional limit

Xinyu Chen, Changsheng Zhu, Bin Lei, Weizhuang Zhuo, Wenxiang Wang, Jiaxiang Ma, Xigang Luo, Ziji Xiang, and Xianhui Chen

Phys. Rev. B 109, 144513 (2024) - Published 10 April, 2024

Charge density waves (CDW) accompanied by superconductivity (SC) is an enduring topic in the field of condensed matter physics for it involves exotic physical properties and quantum states. This paper presents a competitive relationship between the anisotropic SC and CDW down to the two-dimensional limit in ZrTe3, a quasi-one-dimensional material. It reveals an unusual nonmonotonic evolution versus thickness and suggests a complicated superconducting mechanism in this compound.

Structural transition and magnetic anisotropy in αRuCl3

Subin Kim, Ezekiel Horsley, Jacob P. C. Ruff, Beatriz D. Moreno, and Young-June Kim

Phys. Rev. B 109, L140101 (2024) - Published 3 April, 2024

α-RuCl3 is a candidate for realizing the Kitaev quantum spin liquid state. Despite extensive research efforts, its crystal structure at temperatures relevant to studying Kitaev physics has been controversial. Here, the authors examine a single crystal with minimal twinning and stacking faults, allowing them to unambiguously determine the symmetry change across the structural phase transition. They find that the three-fold rotational symmetry of the honeycomb plane is restored in the low-temperature phase with symmetry group R3¯, although this symmetry is explicitly broken in the room-temperature C2/m structure.

Role of photonic angular momentum in all-optical magnetic switching

Muhammad Waleed Khalid, Ali Akbar, Jeongho Ha, Mohammed Salah El Hadri, Alexander V. Sergienko, Eric E. Fullerton, and Abdoulaye Ndao

Phys. Rev. B 109, L140403 (2024) - Published 9 April, 2024

By examining the complex interactions between light and magnetism, this work uncovers the dominant role played by light’s spin angular momentum in magnetic all-optical switching (AOS) using Co/Pt ferromagnetic thin films. The authors use femtosecond vortex beams to demonstrate that the topological charge and orbital angular momentum’s handedness are inconsequential. As a result, this research enhances our comprehension and underscores the pivotal correlation between the angular momentum of light and magnetization dynamics.

Perturbative analysis of quasiperiodic patterning of transmon quantum computers: Enhancement of many-body localization

This paper reports unconventional behavior of the superfluid stiffness Θ(T) in disordered superconductors, such as to amorphous InOx. The authors unveil a remarkable power-law suppression δΘ(T)Tb at TTc, with an exponent b1.6. Through a combination of experiments and theory, they reveal the influence of disorder on this phenomenon, shedding light on the existence of low-energy collective excitations. These findings redefine our understanding of dissipation in inhomogeneous superconductors, with implications for their use in quantum circuits.

The superfluid stiffness Ds(T) is one of the key characteristics of a superconductor, determining the magnetic penetration length and, in two dimensions, the critical temperature. For Galilean invariant systems, it is known that the zero-temperature stiffness takes a universal value DsGal = nm (T=0), while for non-Galilean invariant systems the superfluid stiffness may be suppressed. Here, the authors demonstrate when and how vertex corrections may cancel suppression of the superfluid stiffness at strong coupling.

Charge density waves (CDW) accompanied by superconductivity (SC) is an enduring topic in the field of condensed matter physics for it involves exotic physical properties and quantum states. This paper presents a competitive relationship between the anisotropic SC and CDW down to the two-dimensional limit in ZrTe3, a quasi-one-dimensional material. It reveals an unusual nonmonotonic evolution versus thickness and suggests a complicated superconducting mechanism in this compound.
