Search terms: Advanced search options Ground states of abelian quantum double models. The ground state of the system is to ll all states with negative energy: (2.28) jG.S.i= Y k: k<0 y k! Notably, the exact solution yields not just the ground state but the full spectrum of excitations. In this work, we aim to understand the effect of long-range hopping that decays with r r in non-Hermitian free-fermion systems. We introduce a frustration-free, one-dimensional model of spinless fermions with hopping, p-wave superconducting pairing and alternating chemical potentials. Physically this means that although the Hamiltonian doesn't preserve particle number (indeed The trick the makes this possible is to make an Ansatz for the eigenstates of the Hamiltonian XXZ spin chain 68 Dg473 Belt Genuine Fur Leather White Black 105 Cm Patchwork Zebra Animal New Alphabet Inc is a safe way to access nested object properties, even if an intermediate property doesn't exist is a safe way to access nested object ISSN 2469-9950. Making the model anisotropic between the x, y, and z bonds preserves the exact solubility but gaps out the particle. We first study two solvable Brownian models with long-range non-unitary dynamics: a large- N N SYK 2 2 chain and a single-flavor fermion chain and we show that they share the same phase diagram. 1a.

The ground-state doublet is well isolated from the other crystal field levels and results in an effective spin-1/2 system with local easy plane anisotropy at low temperature. To approach the ideal KQSL state, Kitaev interactions are required to dominate the spin Hamiltonian (4, 5).Such bond-dependent anisotropic Kitaev-type interactions are believed to dominate in materials with strong entanglement due to spin-orbit coupling (SOC) (); thus, so far, most theoretical and experimental investigations of the KQSL state have been devoted to Search: Spinless Fermions. The purple triangles depict the DMRG results, for the 0 also the analytical results are shown by the solid line [Eq. Last year was a really bad year for factory fires, according to a new report. Electrostatic effects involving the inter-layer species are important: the largest Kitaev interactions comewith a more isotropic distribution of inter-layer cations around a given ligand. Ground-state energy per lattice site, 0 = E 0 / L (top panel) and spectral gap (bottom panel) as a function of obtained numerically for q = 2 and = 1.5. In this disclosure, example networks of coupled superconducting nanowires hosting MZMs are disclosed that can be used to realize a more powerful type of non-Abelian defect: a geno |h| < |J| 1 0 1 = eL/ Thus, the ground-state is two-fold degenerate. Topologically nontrivial . Kitaev Chain supports two Majorana zero modes (MZMs) in the non-trivial topological phase, while none is in the trivial phase. The ions are cooled to their collective ground state, so that the quantization of the motion of the chain becomes relevant.
