Impact of further-range exchange and cubic anisotropy on magnetic excitations in the fcc kagome antiferromagnet IrMn3
M. D. LeBlanc, A. A. Aczel, G. E. Granroth +5
Exchange interactions up to fourth nearest neighbor are shown within a classical local-moment Heisenberg approach to be important to model inelastic neutron scattering data on the…
Spin waves in the anisotropic fcc kagome antiferromagnet
M. D. LeBlanc, B. W. Southern, M. L. Plumer +1
Spin wave calculations demonstrate that the macroscopic continuous degeneracy associated with the two-dimensional kagome Heisenberg spin lattice persists in the case of the stacked…
Micromagnetic simulations of sweep-rate dependent coercivity in perpendicular recording media
M. L. Plumer, M. D. Leblanc, J. P. Whitehead +1
The results of micromagnetic simulations are presented which examine the impact of thermal fluctuations on sweep rate dependent coercivities of both single-layer and exchange-coupl…
Radiative Corrections in Nonrelativistic Chern-Simons Theory
D. Caenepeel, M. Leblanc
We present the one-loop scalar field effective potential for the supersymmetric nonrelativistic self-interacting matter fields coupled to an Abelian Chern-Simons gauge field…
Mass Generation for Gauge Fields without Scalars
D. Caenepeel, M. Leblanc
We present an alternative to the Higgs mechanism to generate masses for non-abelian gauge fields in (3+1)-dimensions. The initial Lagrangian is composed of a fermion with current-c…
Effective potential for nonrelativistic non-Abelian Chern-Simons matter system in constant background fields
D. Caenepeel, M. Leblanc
We present the effective potential for nonrelativistic matter coupled to non-Abelian Chern-Simons gauge fields. We perform the calculation using a functional method in constant bac…
Dynamical Mass Generation for Non-Abelian Gauge Fields without the Higgs
Didier Caenepeel, Martin Leblanc
We present an alternative to the Higgs mechanism to generate masses for non-abelian gauge fields in (3+1)-dimensions. The initial Lagrangian is composed of a fermion with current-c…
Structure of the Effective Potential in Nonrelativistic Chern-Simons Field Theory
D. Caenepeel, F. Gingras, M. Leblanc +1
We present the scalar field effective potential for nonrelativistic self-interacting scalar and fermion fields coupled to an Abelian Chern-Simons gauge field. Fermions are non-mini…
Induced term and photon mass generation in 3+1 dimensions
M. Leblanc, R. MacKenzie, P. K. Panigrahi +1
Analysing a 3+1 dimensional model with four-Fermi interactions, we show that topological $\BF$ terms (both abelian and non-abelian) can be induced radiatively by massive fermions a…
Two Dimensional Gauge Theoretic Supergravities
Daniel Cangemi, Martin Leblanc
We investigate two dimensional supergravity theories, which can be built from a topological and gauge invariant action defined on an ordinary surface. We concentrate on four models…
Gauge Formulation of the Spinning Black Hole in (2+1)-Dimensional Anti-de Sitter Space
Daniel Cangemi, Martin Leblanc, Robert B. Mann
We compute the group element of SO(2,2) associated with the spinning black hole found by Bañados, Teitelboim and Zanelli in (2+1)-dimensional anti-de Sitter space-time. We show tha…
Extended Superconformal Galilean Symmetry in Chern-Simons Matter Systems
M. Leblanc, G. Lozano, H. Min
We study the nonrelativistic limit of the supersymmetric Chern-Simons matter system. We show that in addition to Galilean invariance the model admits a set of symmetries gene…
