Topological chiral. An experimental realisation of a system that shows both strong interaction between electrons, e.g., in the form of a Fermi liquid, and spin-orbit coupling is challenging. It requires a system with sufficiently strong relativistic effects to unfold the role of spin-orbit coupling and with a high mobility at a low carrier density to enhance the.

Chiral Topological Phase 2D Fermi Gas With Spin Orbit Coupling.

Abstract Two-dimensional spin-orbit-coupled Fermi gases subject to s -wave pairing can be driven into a topological phase by increasing the Zeeman spin splitting beyond a critical value. In the topological phase, the system exhibits the hallmarks of chiral p -wave superfluidity, including exotic Majorana excitations. The topological protection is demonstrated in Fig. 7a for the case of the 2D Fermi gas, where the Fermi surface is the line p = p F in p x, p y-space. In the extended , p x, p y-space this gives rise to singularity in the Green#x27;s function on the line at which = 0 and p = p F, where the Green#x27;s function is not determined. Coexistence of topological and nontopological Fermi-superfluid phases Abstract The two-dimensional spin-imbalanced Fermi gas subject to s -wave pairing and spin-orbit coupling is considered a promising platform for realizing a topological chiral- p -wave superfluid.

Finally, in a 2D Fermi gas,... Note that such a triplet pairing is similar to a pairing in the Fermi gas with the Rashba spin-orbit coupling,... the spin-orbit coupling includes an in-plane recoiled momentum and hence leads to a chiral p x ip y pairing with a topological Berry phase. On the other hand, in the current case the single.

In TSs, a similar method is also used in investigating the Weyl orbit of Cd 3 As 2, a novel cyclotron orbit combining the Fermi arcs on two opposite surfaces and the bulk chiral Landau level. Distinct from the surface states of TIs, the Weyl orbit acquires an additional quantum phase from the bulk propagation process [41] , [67] , therefore.

Man spin splitting - a prototypical system for developing topological superfluidity in the many-body sector.

The two-dimensional spin-imbalanced Fermi gas subject to s-wave pairing and spin-orbit coupling is considered a promising platform for realizing a topological chiral-p-wave superfluid. In the BCS limit of s-wave pairing, i.e., when Cooper pairs are only weakly bound, the system enters the topological phase via a second-order transition driven by increasing the Zeeman spin-splitting energy. We present the leading gap function symmetries obtained by solving the frequency-dependent linearized Eliashberg equation for the case where spin-orbit coupling is neglected [2]. Session 100: Superconductivity in Ruthenates: 1430: Effects of spin-orbit coupling on the superconducting pairing in Sr2RuO4: Huang, Wen; Zhou, Yi; Yao, Hong. We show that the combination of spin-orbit coupling and in-plane Zeeman field in a two-dimensional degenerate Fermi gas can lead to a larger parameter region for Fulde-Ferrell-Larkin-Ovchinnikov FFLO phases than that using spin-imbalanced Fermi gases. The resulting FFLO superfluids are also more stable due to the enhanced energy difference between FFLO and conventional Bardeen-Cooper.

Jun 10, 2022 Weyl points usually arise when two bands of spin-polarized bands cross in semimetals. The challenge of realizing practical devices with topological semimetals is that their high carrier density makes it difficult to modulate the position of their Fermi level E F and chiral anomaly current, which also results in high static power consumption.

Recent experimental breakthrough in realizing spin-orbit SO coupling for cold atoms has spurred considerable interest in the physics of 2D SO coupled Fermi superfluids, especially topological Majorana fermions MFs which were predicted to exist at zero temperature. However, it is well known that long-range superfluid order is destroyed in 2D by the phase fluctuation at finite temperature. The two-dimensional spin-imbalanced Fermi gas subject to s-wave pairing and spin-orbit coupling is considered a promising platform for realizing a topological chiral-p-wave super uid. In the BCS limit of s-wave pairing, i.e., when Cooper pairs are only weakly bound, the system enters the topo. We present a microscopic theory of Raman scattering in a two-dimensional Fermi liquid FL with Rashba and Dresselhaus types of spin-orbit coupling, and subject to an in-plane magnetic field B. In the long-wavelength limit, the Raman spectrum probes the collective modes of such a FL: the chiral spin waves. The characteristic features of these modes are a linear-in-q term in the dispersion.

We investigate the quasiparticle excitations in the FFLO- type helical state of a superconductor with inversion-symmetry breaking and strong Rashba spin-orbit coupling. We restrict to a state with. For a 2D Fermi gas without SOC, a temperature of T 0.27 TF has recently been reported 48. With these, it is reasonable to expect that the tFF state can be prepared and probed in future.

May 01, 2021 The observed unusual dampinglike torque arises from the planar Hall current generated by spinorbit coupling in a FM conductor and absorbed by the adjacent NM layers when the efficiency of the spin transfer at one of the NM/FM interfaces is large and the NM is a good spin sink, which may play a significant role in the SOT switching in. As the Fermi-Fermi pairing interaction is tuned, the background Fermi superfluid undergoes a topological phase transition. We show that such a transition is accompanied by a discontinuity in the second derivative of the polaron energy, regardless of the impurity-fermion interaction.... Our results suggest the possibility of using the impurity.
