Phase diagram of a uniform two-dimensional Fermi gas with spin-orbit.

Jan 21, 2020 · Topological Systems and Spin-Orbit Coupling. Phase transitions in condensed matter physics generally have been identified with an order parameter that spontaneously breaks the symmetry of the system and develops long range order, such as for the magnetization that develops in a ferromagnet below the Curie temperature or the staggered.

Oxide magnonics: Spin waves in functional magnetic oxides.

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.

Nov 17, 2022 · Here, we have reported the calculation of the 2D superconducting dome for a 3 nm superlattice of quantum wells with Rashba spin–orbit coupling. The Rashba coupling induces an unconventional Lifshitz transition associated with a VHS extended on a circumference of increasing radius with the intensity RSOC in negative helicity states. 61 61. Superconductor with strong spin-orbit coupling, when arranged in a 2D lattice, can yield a 2D topological chiral p-wave superconductor whose chiral Majorana edge modes can be observed in scanning tunneling microscope measurements. To shed light on the rich range of possibilities, we analyse the topological properties of a system with dense.

Apr 21, 2011 · We show that this scheme generates a Fermi surface spin texture for 40K atoms, which is observable in time-of-flight measurements. The chiral spin texture, together with conventional s -wave interactions, leads to topological superconductivity and non-Abelian Majorana quasiparticles. Received 7 January 2011. A systematic theoretical study of the BCS-BEC crossover in two-dimensional Fermi gases with Rashba spin-orbit coupling shows that the SOC enhances the formation of the bound state: the binding energy E(B) and effective mass m(B), which grows along with the increase of the SOC. We present a systematic theoretical study of the BCS-BEC crossover in two-dimensional Fermi gases with Rashba spin.

Nov 30, 2012 · We predict the existence of chiral spin waves-collective modes in a two-dimensional Fermi liquid with the Rashba or Dresselhaus spin-orbit coupling. Starting from the phenomenological Landau theory, we show that the long-wavelength dynamics of magnetization is governed by the Klein-Gordon equations..
