Simulating spin dynamics with quantum computers
Jarrett L. Lancaster, D. Brysen Allen
IBM quantum computers are used to simulate the dynamics of small systems of interacting quantum spins. For time-independent systems with fewer than three spins, we compute the exac…
The spin-1 ladder : A bosonization study
D. Allen, D. Sénéchal
We construct a field-theoretic description of two coupled spin-1 Heisenberg chains, starting with the known representation of a single spin-1 chain in terms of Majorana fermions (o…
The fate of spinons in spontaneously dimerised spin-1/2 ladders
Dave Allen, Fabian H. L. Essler, Alexander A. Nersesyan
We study a weakly coupled, frustrated two-leg spin-1/2 Heisenberg ladder. For vanishing coupling between the chains, elementary excitations are deconfined, gapless spin-1/2 objects…
Non-Abelian bosonization of the frustrated antiferromagnetic spin-1/2 chain
Dave Allen, David Senechal
We study the spin-1/2 chain with nearest neighbor () and next-nearest neighbor () interactions in the regime , which is equivalent to two chains with a `zig-z…
Semi-classical description of the frustrated antiferromagnetic chain
D. Allen, D. Senechal
The antiferromagnetic Heisenberg model on a chain with nearest and next nearest neighbor couplings is mapped onto the nonlinear sigma model in the continuum limit. In one s…
