Broken symmetries in topological condensed matter systems have implications for the spectrum of Fermionic excitations confined on surfaces or topological defects. The Fermionic spectrum of confined (quasi2D)^{3}HeA consists of branches of chiral edge states. The negative energy states are related to the groundstate angular momentum,
Unlike their fermionic counterparts, the dynamics of Hermitian quadratic bosonic Hamiltonians are governed by a generally nonHermitian Bogoliubovde Gennes effective Hamiltonian. This underlying nonHermiticity gives rise to a

Abstract , for ${L}_{z}=(N/2)\hslash $ Cooper pairs. The power law suppression of the angular momentum, $N/2$ for ${L}_{z}(T)\simeq (N/2)\hslash [1\frac{2}{3}(\pi T/\mathrm{\Delta}{)}^{2}]$ , in the fully gapped 2D chiral Aphase reflects the thermal excitation of the chiral edge Fermions. We discuss the effects of wave function overlap, and hybridization between edge states confined near opposing edge boundaries on the edge currents, groundstate angular momentum and groundstate order parameter of superfluid^{3}He thin films. Under strong lateral confinement, the chiral A phase undergoes a sequence of phase transitions, first to a pair density wave (PDW) phase with broken translational symmetry at $0\u2a7dT\ll {T}_{c}$ . The PDW phase is described by a periodic array of chiral domains with alternating chirality, separated by domain walls. The period of PDW phase diverges as the confinement length ${D}_{c2}\sim 16{\xi}_{0}$ . The PDW phase breaks timereversal symmetry, translation invariance, but is invariant under the combination of timereversal and translation by a onehalf period of the PDW. The mass current distribution of the PDW phase reflects this combined symmetry, and originates from the spectra of edge Fermions and the chiral branches bound to the domain walls. Under sufficiently strong confinement a secondorder transition occurs to the nonchiral ‘polar phase’ at $D\to {D}_{{c}_{2}}$ , in which a single pwave orbital state of Cooper pairs is aligned along the channel. ${D}_{c1}\sim 9{\xi}_{0}$ 
Abstract The genericity of Arnold diffusion in the analytic category is an open problem. In this paper, we study this problem in the following
a priori unstable Hamiltonian system with a timeperiodic perturbation where ${\mathcal{H}}_{\epsilon}(p,q,I,\phi ,t)=h(I)+\sum _{i=1}^{n}\pm \left(\frac{1}{2}{p}_{i}^{2}+{V}_{i}({q}_{i})\right)+\epsilon {H}_{1}(p,q,I,\phi ,t),$ , $(p,q)\in {\mathbb{R}}^{n}\times {\mathbb{T}}^{n}$ with $(I,\phi )\in {\mathbb{R}}^{d}\times {\mathbb{T}}^{d}$n ,d ⩾ 1,V _{i}are Morse potentials, andɛ is a small nonzero parameter. The unperturbed Hamiltonian is not necessarily convex, and the induced inner dynamics does not need to satisfy a twist condition. Using geometric methods we prove that Arnold diffusion occurs for generic analytic perturbationsH _{1}. Indeed, the set of admissibleH _{1}isC ^{ω}dense andC ^{3}open (a fortiori ,C ^{ω}open). Our perturbative technique for the genericity is valid in theC ^{k}topology for allk ∈ [3, ∞) ∪ {∞,ω }. 
In this paper, we consider the linear convectiondiffusion equation in one dimension with periodic boundary conditions, and analyze the stability of fully discrete methods that are defined with local discontinuous Galerkin (LDG) methods in space and several implicitexplicit (IMEX) RungeKutta methods in time. By using the forward temporal differences and backward temporal differences, respectively, we establish two general frameworks of the energymethod based stability analysis. From here, the fully discrete schemes being considered are shown to have monotonicity stability, i.e. the
$L^2$ norm of the numerical solution does not increase in time, under the time step condition$\tau \le \mathcal {F}(h/c, d/c^2)$ , with the convection coefficient$c$ , the diffusion coefficient$d$ , and the mesh size$h$ . The function$\mathcal {F}$ depends on the specific IMEX temporal method, the polynomial degree$k$ of the discrete space, and the mesh regularity parameter. Moreover, the time step condition becomes$\tau \lesssim h/c$ in the convectiondominated regime and it becomes$\tau \lesssim d/c^2$ in the diffusiondominated regime. The result is improved for a first order IMEXLDG method. To complement the theoretical analysis, numerical experiments are further carried out, leading to slightly stricter time step conditions that can be used by practitioners. Uniform stability with respect to the strength of the convection and diffusion effects can especially be relevant to guide the choice of time step sizes in practice, e.g. when the convectiondiffusion equations are convectiondominated in some subregions. 
Abstract CeOs_{4}Sb_{12}, a member of the skutterudite family, has an unusual semimetallic lowtemperature
phase that inhabits a wedgelike area of the field $\mathcal{L}$H —temperatureT phase diagram. We have conducted measurements of electrical transport and megahertz conductivity on CeOs_{4}Sb_{12}single crystals under pressures of up to 3 GPa and in high magnetic fields of up to 41 T to investigate the influence of pressure on the differentH –T phase boundaries. While the hightemperature valence transition between the metallic phase and the $\mathcal{H}$ phase is shifted to higher $\mathcal{L}$T by pressures of the order of 1 GPa, we observed only a marginal suppression of the phase that is found below 1 K for pressures of up to 1.91 GPa. Highfield quantum oscillations have been observed for pressures up to 3.0 GPa and the Fermi surface of the highfield side of the $\mathcal{S}$ phase is found to show a surprising decrease in size with increasing pressure, implying a change in electronic structure rather than a mere contraction of lattice parameters. We evaluate the fielddependence of the effective masses for different pressures and also reflect on the sample dependence of some of the properties of CeOs_{4}Sb_{12}which appears to be limited to the lowfield region. $\mathcal{H}$ 
Abstract Chiral and helical Majorana fermions are two archetypal edge excitations in twodimensional topological superconductors. They emerge from systems of different Altland–Zirnbauer symmetries and characterized by
and $\mathbb{Z}$ topological invariants respectively. It seems improbable to tune a pair of copropagating chiral edge modes to counterpropagate in a single system without symmetry breaking. Here, we explore the peculiar behaviors of Majorana edge modes in topological superconductors with an additional ‘mirror’ symmetry which changes the bulk topological invariant to ${\mathbb{Z}}_{2}$ type. A theoretical toy model describing the proximity structure of a Chern insulator and a $\mathbb{Z}\oplus \mathbb{Z}$p _{x}wave superconductor is proposed and solved analytically to illustrate a direct transition between two topologically nontrivial phases. The weak pairing phase has two chiral Majorana edge modes, while the strong pairing phase is characterized by mirrorgraded Chern number and hosts a pair of counterpropagating Majorana fermions protected by the mirror symmetry. The edge theory is worked out in detail, and implications to braiding of Majorana fermions are discussed.
