Superconducting dome in ferroelectric-type materials from soft mode instability

Chandan Setty, Matteo Baggioli, and Alessio Zaccone

Phys. Rev. B 105, L020506 (2022) - Published 25 January, 2022

An unexpectedly simple extension to a theory explains the critical temperature anomalies observed in ferroelectric superconductors.

Reaching the equilibrium state of the frustrated triangular Ising magnet Ca3Co2O6

Ivan Nekrashevich, Xiaxin Ding, Fedor Balakirev, Hee Taek Yi, Sang-Wook Cheong, Leonardo Civale, Yoshitomo Kamiya, and Vivien S. Zapf

Phys. Rev. B 105, 024426 (2022) - Published 31 January, 2022

Ca3Co2O6 is a triangular frustrated Ising magnet whose magnetic properties have puzzled the community for decades and have generated many theoretical descriptions. The magnetization shows regular steps with magnetic field that are metastable for days to weeks at low temperatures. Here, the authors explore ways to bypass metastability and reach the ground state. They compare Monte Carlo simulations and different experimental approaches to identify the elusive ground state.

Characterizing two-dimensional superconductivity via nanoscale noise magnetometry with single-spin qubits

Pavel E. Dolgirev, Shubhayu Chatterjee, Ilya Esterlis, Alexander A. Zibrov, Mikhail D. Lukin, Norman Y. Yao, and Eugene Demler

Phys. Rev. B 105, 024507 (2022) - Published 10 January, 2022

Atomically thin materials are highly versatile platforms to sharpen our understanding of two-dimensional superconductivity. However, such materials are not amenable to many conventional experimental techniques used for three-dimensional superconductors, making it difficult to probe the origin and symmetry of Cooper pairing. To investigate superconducting transitions and access the pairing wave function, the authors propose a wireless, table-top probe - noise magnetometry by a single-spin qubit. The technique can elucidate various nonlocal transport regimes inaccessible to other probes. It can also detect elusive collective modes like Josephson plasmons.

Superconducting piezoelectric effect

Michiya Chazono, Hikaru Watanabe, and Youichi Yanase

Phys. Rev. B 105, 024509 (2022) - Published 12 January, 2022

The authors propose a supercurrent-induced lattice distortion in superconductors lacking both inversion and time-reversal symmetry. They dub this the superconducting piezoelectric effect (SCPE). They demonstrate the effect for a two-dimensional Rashba superconductor under in-plane magnetic field, in which Cooper pairs have finite total momentum, and clarify the close relation between the SCPE and momentum. The SCPE is a phenomenon unique to superconductors. It could become a sensitive probe of symmetry-breaking effects and of Cooper-pair momentum in exotic superconductors.

Elasto-Raman scattering: Arsenic optical phonon as a probe of nematicity in BaFe2As2

Jean-Côme Philippe, Jimmy Faria, Anne Forget, Dorothée Colson, Sarah Houver, Maximilien Cazayous, Alain Sacuto, and Yann Gallais

Phys. Rev. B 105, 024518 (2022) - Published 24 January, 2022

Nematicity in the iron-based superconductor parent compound BaFe2As2 is studied using Raman scattering under tunable uniaxial strain. The authors use the polarization-resolved arsenic phonon intensity to monitor the nematic order parameter as a function of both temperature and strain. This elasto-Raman approach showcases the interest of combining anisotropic strain with a symmetry-resolved probe such as Raman scattering. It can be applied to a wide variety of quantum materials where strain can serve as a nonthermal control parameter.

Interplay between magnetism and superconductivity in UTe2

Di S. Wei, David Saykin, Oliver Y. Miller, Sheng Ran, Shanta R. Saha, Daniel F. Agterberg, Jörg Schmalian, Nicholas P. Butch, Johnpierre Paglione, and Aharon Kapitulnik

Phys. Rev. B 105, 024521 (2022) - Published 26 January, 2022

Time-reversal symmetry breaking in the strongly paramagnetic UTe2 is inferred from its spontaneous Kerr response below the superconducting critical temperature Tc. Focusing a Sagnac interferometer beam on the center of the sample, the authors present an extensive study of the magnetic-field-trained Kerr effect in this material, particularly of the nature of the critical state, which is dominated by magnetic vortices. Measurements in the presence of magnetic field reveal the competition between vortex-induced magnetization and the shielding currents of the superconductor.

Characterizing many-body localization via exact disorder-averaged quantum noise

Michael Sonner, Alessio Lerose, and Dmitry A. Abanin

Phys. Rev. B 105, L020203 (2022) - Published 31 January, 2022

Systems with quenched disorder host fascinating dynamical phases including many-body localization. Theoretical description of such phases proves challenging since it requires disorder-averaging over many configurations, and very rare configurations may have an important effect. Here, the authors introduce a new method, based on the Feynman-Vernon influence functional, that allows one to directly access the disorder-averaged dynamics of quantum spin chains. This formulation provides a starting point for describing the many-body localization transition using variational and analytical techniques.

Nonsymmorphic symmetry and field-driven odd-parity pairing in CeRh2As2

D. C. Cavanagh, T. Shishidou, M. Weinert, P. M. R. Brydon, and Daniel F. Agterberg

Phys. Rev. B 105, L020505 (2022) - Published 24 January, 2022

CeRh2As2 has attracted attention for a field-induced transition between two distinct superconducting states. The authors argue that the nonsymmorphic symmetry of the crystal lattice enables this. This symmetry enforces the spin polarization of the Bloch states at the Brillouin zone edges to be parallel to the edges. Such a spin polarization ensures a near-degeneracy between even- and odd-parity superconducting channels, provided the Fermi surface sits near these edges. First-principles calculations incorporating electronic correlations reveal a Fermi surface consistent with this picture.

Atomically thin materials are highly versatile platforms to sharpen our understanding of two-dimensional superconductivity. However, such materials are not amenable to many conventional experimental techniques used for three-dimensional superconductors, making it difficult to probe the origin and symmetry of Cooper pairing. To investigate superconducting transitions and access the pairing wave function, the authors propose a wireless, table-top probe - noise magnetometry by a single-spin qubit. The technique can elucidate various nonlocal transport regimes inaccessible to other probes. It can also detect elusive collective modes like Josephson plasmons.

The authors propose a supercurrent-induced lattice distortion in superconductors lacking both inversion and time-reversal symmetry. They dub this the superconducting piezoelectric effect (SCPE). They demonstrate the effect for a two-dimensional Rashba superconductor under in-plane magnetic field, in which Cooper pairs have finite total momentum, and clarify the close relation between the SCPE and momentum. The SCPE is a phenomenon unique to superconductors. It could become a sensitive probe of symmetry-breaking effects and of Cooper-pair momentum in exotic superconductors.

Nematicity in the iron-based superconductor parent compound BaFe2As2 is studied using Raman scattering under tunable uniaxial strain. The authors use the polarization-resolved arsenic phonon intensity to monitor the nematic order parameter as a function of both temperature and strain. This elasto-Raman approach showcases the interest of combining anisotropic strain with a symmetry-resolved probe such as Raman scattering. It can be applied to a wide variety of quantum materials where strain can serve as a nonthermal control parameter.

Time-reversal symmetry breaking in the strongly paramagnetic UTe2 is inferred from its spontaneous Kerr response below the superconducting critical temperature Tc. Focusing a Sagnac interferometer beam on the center of the sample, the authors present an extensive study of the magnetic-field-trained Kerr effect in this material, particularly of the nature of the critical state, which is dominated by magnetic vortices. Measurements in the presence of magnetic field reveal the competition between vortex-induced magnetization and the shielding currents of the superconductor.
