Second-order shaped pulses for solid-state quantum computation
Leonid P. Pryadko, Pinaki Sengupta
We present the constructon and detailed analysis of highly-optimized self-refocusing pulse shapes for several rotation angles. We characterize the constructed pulses by the coeffic…
Exchange parameters of copper-based quasi-two-dimensional Heisenberg magnets measured using high magnetic fields and muon-spin rotation
P. A. Goddard, J. Singleton, P. Sengupta +9
Pulsed-field magnetization experiments (fields of up to 85 T and temperatures down to 0.4 K) are reported on nine organic Cu-based two-dimensional (2D) Heisenberg magnets.…
Ordered magnetic phases of the frustrated spin-dimer compound Ba3Mn2O8
E. C. Samulon, Y. -J. Jo, P. Sengupta +4
Ba3Mn2O8 is a spin-dimer compound based on pairs of S=1, 3d^2, Mn^{5+} ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state…
Ground state and thermal transitions in Field Induced spin-Supersolid Phase
P. Sengupta, C. D. Batista
We use a quantum Monte Carlo method to study the ground state and thermodynamic phase transitions of the spin supersolid phase in the S=1 Heisenberg model with uniaxial anisotropy.…
