Recent theoretical research has focused on exciting new types of phase transitions that do not appear to fit within standard paradigms. In so-called deconfined quantum phase transitions, the conventional quasiparticle used in standard mathematical descriptions must be replaced by fractionalized (“split-up”) quasiparticles. Here, the authors present calculations aimed directly at the most promising experimental investigations, where the quasiparticles or their fractionalized parts are directly probed, for example, by neutron scattering. They present calculations of the spectral functions measured in such experiments to exhibit the deconfined transition and fractionalization phenomenon therein between a magnetic and a nonmagnetic phase. These results are useful for interpreting experimental results and guiding searches for deconfined phase transitions in quantum materials consisting of layered structures, in which the interactions between electrons are strong and lead to unconventional electronic and magnetic properties.

All-optical radio-frequency modulation of Anderson-localized modes

Tuning spin-charge interconversion with quantum confinement in ultrathin bismuth films

Spin-charge interconversion (SCI) phenomena are now at the core of the field of spin-orbitronics. They allow to generate or detect spin currents in nonmagnetic materials and to manipulate the magnetization of nanomagnets by spin-orbit torque. Here, the authors show that spin-charge interconversion can be tuned by quantum size effects in ultrathin bismuth films. Epitaxially grown on germanium, bismuth first forms nanocrystals with a size less than the electron Fermi wavelength. Quantum confinement in these nanocrystals leads to high bulk resistance which can be interpreted as a semimetal-to-semiconductor transition. They also exhibit metallic surface states with a characteristic helical spin texture at the Fermi contour as shown by spin-resolved photoemission spectroscopy. Hence, when generating a spin current in germanium, it is converted into a charge current uniquely in the bottom surface states of bismuth nanocrystals. When increasing the amount of deposited bismuth, nanocrystals grow and begin to form a continuous semimetallic film suppressing quantum confinement. The spin-to-charge conversions into the top and bottom surfaces cancel each other. Thus, quantum confinement can turn on and off SCI in ultrathin bismuth films.

Gradient-based hybrid quantum-classical algorithms are often initialised with random, unstructured guesses. Here, the authors show that this approach will fail in the long run, due to the exponentially-small probability of finding a large enough gradient along any direction.

Random-field Ising-like effective theory of the glass transition. I. Mean-field models

Author(s): Giulio Biroli, Chiara Cammarota, Gilles Tarjus, and Marco Tarzia

Almost any liquid when cooled fast enough forms an amorphous solid, called a glass. Here, the authors develop an effective theory of the glass transition that is able to include nonperturbative fluctuations due to self-induced disorder. Their approach allows a reformulation of the problem in terms of simpler models originally introduced to describe disordered magnetic systems. The authors discuss the physical implications of such a mapping, including the possibility to determine the existence or not of an underlying finite-temperature thermodynamic glass transition in supercooled liquids.

One of the ultimate goals for future spintronic applications is to manipulate magnetic states of matter on the shortest of timescales. Here, the authors investigate the optically induced ultrafast demagnetization and remagnetization dynamics of ferromagnetic alloys based on either intrinsic or induced magnetic moments. Using pump-probe spectroscopy in combination with dynamic spin model simulations, they find that a CoFeB alloy with intrinsic magnetic moments on the Fe and Co sites reveals a distinct asymptotic amplitude limit of the remagnetization process, while in FePt the induced moments of the Pt sites stay always proportional to those of Fe.

Spin fluctuations are often considered to be an important ingredient for superconductivity in the iron-based superconductors. Here, the authors use angle-resolved photoemission spectroscopy to study both the momentum dependence of the superconducting gap of FeSe and the orbital content of the bands. The experimental observation of a direct scaling between a particular orbital character and gap magnitude, paired with theoretical calculations, provides strong evidence in favor of spin fluctuation mediated superconductivity in FeSe.

Author(s): Leonardo Mazza, Fernando Iemini, Marcello Dalmonte, and Christophe Mora

Topological order and spontaneous symmetry breaking are typically thought of as paradigmatic, yet antipodal, phenomena in correlated quantum matter. Here, the authors show instead that they can concomitantly act to determine the ground-state properties of interacting systems, providing a novel angle for the discussion of topological phenomena and parafermions in one-dimensional fermionic systems. They show that topological Majorana modes can coexist with ℤn spontaneous symmetry breaking by discussing a lattice model of one-dimensional spinless fermions and thoroughly characterize the presence of nontopological parafermions.

Author(s): Alessio Calzona, Tobias Meng, Maura Sassetti, and Thomas L. Schmidt

Nonlocal (topological) order and local (Landau-type) order are often viewed as opposing principles. Here, the authors study strongly interacting quantum wires that exhibit hybrid order, composed of local Ising magnetization and a topological order parameter. Based on an exact mapping of the corresponding strongly interacting electronic Hamiltonian onto ℤn parafermions, they show that the system can be in a hybrid phase which is distinct from the topological and from the Ising phase. Moreover, the system has remarkable similarities to superconducting hybrid devices built from fractional quantum Hall edge states, which can host parafermions useful for quantum computation.

Spin transport in a graphene normal-superconductor junction in the quantum Hall regime

By Tibor Sekera, Christoph Bruder, and Rakesh P. Tiwari from Recent Articles in Phys. Rev. B. Published on Nov 13, 2018.

Author(s): Tibor Sekera, Christoph Bruder, and Rakesh P. Tiwari

In graphene-superconductor heterostructures, superconductivity and the quantum Hall effect may coexist for an experimentally accessible range of magnetic fields. When the graphene edge states are coupled to a superconductor in the presence of a Zeeman field, the charge carriers with one spin projection get transmitted while the ones with the opposite spin projection get reflected within a certain energy region. This spin-filtering effect is a consequence of the interplay between specular Andreev reflections and Andreev retro-reflections. While the edge termination of graphene and the geometrical details do matter for the charge conductance, they have little effect on the spin polarization of the charge carriers.

Working in two spatial dimensions at zero temperature, we find that closely spaced perfect chromoelectric conductors attract each other with a small anomalous scaling dimension....
