Dynamical Properties of one dimensional Mott Insulators

Davide Controzzi, Fabian H. L. Essler, Alexei M. Tsvelik

At low energies the charge sector of one dimensional Mott insulators can be described in terms of a quantum Sine-Gordon model. Using exact results derived from integrability it is…

Experimental realization of a 2D fractional quantum spin liquid

R. Coldea, D. A. Tennant, A. M. Tsvelik +1

The ground-state ordering and dynamics of the two-dimensional (2D) S=1/2 frustrated Heisenberg antiferromagnet Cs_2CuCl_4 is explored using neutron scattering in high magnetic fiel…
