Topological spin waves in the atomic-scale magnetic skyrmion crystal
(IOP, 2016)
We study the spin waves of the triangular skyrmion crystal that emerges in a two-dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalonshinkii-Moriya interactions, Zeeman coupling ...

Fractional Spin and Josephson Effect in Time-Reversal-Invariant Topological Superconductors
(American Physical Society, 2017-07)
Time-reversal-invariant topological superconducting (TRITOPS) wires are known to host a fractional spin /4 at their ends. We investigate how this fractional spin affects the Josephson current in a TRITOPS-quantum dot-TRITOPS ...
Higher spin analogs of linearized topologically massive gravity and linearized new massive gravity
(2021-10-15)
We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in D=2+1. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor without extra auxiliary ...

Hamiltonian analysis and positivity of a new massive spin-2 model
(2022-02-03)
Recently a new model has been proposed to describe free massive spin-2 particles in D dimensions in terms of a non symmetric rank-2 tensor e μν and a mixed symmetry tensor B μ[αβ]. The model is invariant under linearized ...
Geometric vector potentials from nonadiabatic spin dynamics
(American Physical Society, 2017-07)
We propose a theoretical framework that captures the geometric vector potential emerging from the nonadiabatic spin dynamics of itinerant carriers subject to arbitrary magnetic textures. Our approach results in a series ...

Charge Ordering in a Pure Spin Model: Dipolar Spin Ice
(Amer Physical Soc, 2013-10-04)
We study the dipolar spin-ice model at fixed density of single excitations, rho, using a Monte Carlo algorithm where processes of creation and annihilation of such excitations are banned. In the limit of rho going to zero, ...
