Topological phenomena in two-dimensional materials are characterized by an electrical conductivity that is restricted to the edges of a sample. A heterostructure of the semiconductors indium arsenide and gallium antimonide, InAs/GaSb, can be a quantum spin Hall insulator (QSHI), which exhibits spin-resolved channels at the edges but has an insulating bulk. The QSHI is linked to a nontrivial inverted band structure that emerges only for certain thicknesses of the InAs and GaSb layers. Here, the authors have exposed InAs/GaSb samples to variable compressive and tensile strain through piezo-electric elements. It is observed that the system’s electrical properties are very susceptible to even small values of such mechanical deformation. Band structure calculations reveal the impact of strain on the nontrivial electronic band structure and highlight the potential of strain-engineering for the observation of the quantum spin Hall insulating phase in this material system.
Spin-orbit coupling and strong electronic correlations in cyclic molecules

Here, the authors show that in molecules there is an emergent spin molecular-orbital coupling (SMOC) that is not merely inherited from the atomic scale. This causes the spin of electrons to become entangled with currents running around the molecule. Molecules that are symmetric only under rotation by 2/, provide a striking example. For odd there is a ladder of orbital states and SMOC allows the system to climb up or down the ladder, much like spin-orbit coupling in atoms. However, for even there is a ring of states – SMOC can move the system around in either directions, without ever reaching a minimum or maximum. This is a consequence of the umklapp spin-orbit scattering present in even- molecules that is precluded in odd- molecules by time-reversal symmetry. The authors show that SMOC is large in organometallic complexes and explore how synthetic chemistry can be used to control SMOC. Such control has numerous potential applications.

Here, the authors make connection to the foundation of quantum mechanics. As stated by Schrödinger, entanglement is “the characteristic trait of quantum mechanics” and seemingly at odds with the description of nature. In this joint experimental and theoretical work, the authors discuss the possibility of spin entanglement of two freely propagating electrons. These have been created by a collision of a spin-polarized primary electron with the Shockley surface state of the Cu(111) surface. The contribution of this state can clearly be identified in the experiment and allows use of its particular features. The electron scattering study done here resembles the scenario envisioned by the seminal works of Einstein-Podolsky-Rosen and Schrödinger to work out the peculiar nature of entanglement.

Quantum spin liquids can be well described in the language of gauge theory. While most theoretical effort has been focused on gauge theories with a familiar vector gauge field, there exists a stable class of quantum spin liquids described by higher-rank tensor gauge fields. Here, the authors focus on a class of stable three-dimensional spin liquids described by symmetric tensor (1) gauge fields. They find that these spin liquids feature an exotic class of excitations that are restricted to motion along lower-dimensional subspaces, a phenomenon seen earlier in fracton models. They show how this subdimensional behavior follows naturally from a set of higher-moment charge conservation laws that place severe restrictions on particle motion. This work opens up an exciting new direction in the field of spin liquids.

Sachdev-Ye-Kitaev model and thermalization on the boundary of many-body localized fermionic symmetry-protected topological states

Phys. Rev. B 95, 115150 (2017) - Published 28 March, 2017
The Sachdev-Ye-Kitaev (SYK) model is a quantum mechanical model for randomly interaction fermions in a quantum dot. This paper studies the properties of the many-body spectrum of the SYK model and finds a periodicity of the spectral properties in term of the number of fermion modes in the quantum dot. In particular, the level statistics of SYK spectrum are investigated. It is found that the many-body level spacing of the SYK model follows Wigner-Dyson statistics, consistent with the thermalizing nature of the SYK model. Interestingly, the level statistics goes through those of different random matrix ensembles periodically. The periodicity can be explained by viewing the SYK model as an effective model for the boundary of 1D interacting fermionic symmetry-protected topological states. The periodicity in the SYK spectrum is therefore tied to the classification of fermionic topological states in one dimension.
Superconducting and ferromagnetic phase diagram of UCoGe probed by thermal expansion

The superconducting ferromagnet UCoGe is a versatile laboratory tool to investigate the interplay of ferromagnetism ( = 3.0 K) and superconductivity ( = 0.6 K). Here, the authors report the superconducting and magnetic phase diagram in the field-temperature plane determined by thermal expansion measurements. The use of the thermal expansion technique has the advantage that it involves a thermodynamic bulk probe. The experiments were carried out on a single crystal in fixed magnetic fields applied along the principal axes of the orthorhombic crystal. Since the phase diagram depends sensitively on the orientation of the magnetic field with respect to the crystal axes, the thermal expansion cell was mounted on a piezoelectric rotator to enable tuning of the magnetic field angle. The authors observe that the Curie point for || shifts gradually to lower temperatures and present bulk-sensitive evidence for the unusual S-shaped curve for the same field orientation. The results lend further support to theoretical proposals of spin-fluctuation mediated enhancement of superconductivity in a magnetic field ( || ).

Quantum mechanics nominally works in a space of infinite dimensions. In practice, however, the computer-based solution of quantum-mechanical problems relies on a restriction of that space to a high but finite number of dimensions. This is important since computational quantum-mechanical simulations have a huge presence in today’s physical science. In many instances, the finite-dimensional space needs to evolve during a simulation. In this work, the authors extend the formalism used for finite spaces to that of evolving spaces. Here, well-known equations acquire a new meaning in the language of the curved spaces familiar to general relativity. The authors provide a novel geometric approach to calculating tensorially well-defined derivatives of quantum-mechanical state and operator representations with respect to arbitrary external parameters. Contributions due to basis function evolution play the role of the Christoffel symbol terms of Riemannian geometry. The curvature of the resulting geometry is equivalent to Berry’s curvature, but generalized for possibly nonorthogonal, smoothly varying basis functions. This work provides insights into dynamical quantum simulations that enable the development of improved simulation algorithms. It also opens up new scientific horizons, as is ever the case when establishing formal links between different subfields of physics.
