“…The points of the strength reduction method is that the shear strength of the soil are reduced simultaneously assuming the external force keeps constant and then the finite element analysis is carried out to analyse the stress and strain until the destruction of the slope. Zhao and Zheng [10] believed that the safety coefficients obtained by Bishop method and strength reduction method possess the same physical meaning and the essential of two methods are also same.…”

Abstract. In order to evaluate the accuracy of strength reduction method using FEM, the safety factors of the uniform clay slope and sand slope are investigated by Fellenius's method, Bishop's method using traditional limit equilibrium method and strength reduction method respectively. The limit equilibrium method is carried out based on the code for foundations in port engineering and the FE analysis is based on Plaxis3D. The results show that the safety coefficient obtained by strength reduction method of FEM is larger than that obtained by limit equilibrium method and the errors are 6.03% and 1.61% for clay slope and 8.54% and 3.99% for sand slope.

“…It is essential in many physical applications of the model. In planar condensed matter systems the energy gap can be generated by a number of mechanisms (see, for example, [4,5,[46][47][48][49][80][81][82][83][84] and references therein). The latter include the breaking of symmetry between the sublattices by introducing a staggered on-site energy, the deformations of bonds in the lattice, fermion contact interactions and the statistical gauge interactions.…”

We evaluate the fermion condensate and the expectation values of the charge and current densities for a massive fermionic field in (2 + 1)-dimensional conical spacetime with a magnetic flux located at the cone apex. The consideration is done for both irreducible representations of the Clifford algebra. The expectation values are decomposed into the vacuum expectation values and contributions coming from particles and antiparticles. All these contributions are periodic functions of the magnetic flux with the period equal to the flux quantum. Related to the non-invariance of the model under the parity and time-reversal transformations, the fermion condensate and the charge density have indefinite parity with respect to the change of the signs of the magnetic flux and chemical potential. The expectation value of the radial current density vanishes. The azimuthal current density is the same for both the irreducible representations of the Clifford algebra. It is an odd function of the magnetic flux and an even function of the chemical potential. The behavior of the expectation values in various asymptotic regions of the parameters are discussed in detail. In particular, we show that for points near the cone apex the vacuum parts dominate. For a massless field with zero chemical potential the fermion condensate and charge density vanish. Simple expressions are derived for the part in the total charge induced by the planar angle deficit and magnetic flux. Combining the results for separate irreducible representations, we also consider the fermion condensate, charge and current densities in parity and time-reversal symmetric models. Possible applications to graphitic nanocones are discussed. a

“…The hopping parameter β is related to the probability amplitude for electron transfer between neighbouring sites [6][7][8][9][10][11][12]. Though for an ideal single layer graphene ε = 0, by breaking the sublattice symmetry a gap can be introduced in graphene [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] and in our following work we shall consider the massive Dirac excitations of a gapped graphene cone.…”

“…The Dirac type excitations in pristine graphene are gapless. However, various impurities, electron-electron interactions, substrate structures and other short distance effects can violate the sublattice symmetry in graphene, leading to a mass gap which has attracted both theoretical [33][34][35][36][37][38][39][40][41][42][43] and experimental [44][45][46][47][48][49][50] attention. Thus, the gapped graphene system provides a unique template to study the nonperturbative quantum features of massive Dirac fermions in the presence of a topological defect.…”

We study the combined effect of a conical topological defect and a Coulomb charge impurity on the dynamics of Dirac fermions in gapped graphene. Beyond a certain strength of the Coulomb charge, quantum instability sets in, which demarcates the boundary between sub and supercritical values of the charge. In the subcritical regime, for certain values of the system parameters, the allowed boundary conditions in gapped graphene cone can be classified in terms of a single real parameter. We show that the observables such as local density of states, scattering phase shifts and the bound state spectra are sensitive to the value of this real parameter, which is interesting from an empirical point of view. For a supercritical Coulomb charge, we analyze the system with a regularized potential as well as with a zigzag boundary condition and find the effect of the sample topology on the observable features of the system.
