Observation of multipartite spin entanglement in a cuprate chain
S. F. R. TenHuisen, Z. Shen, V. Bhartiya +17
Quantum materials are believed to host highly entangled states of matter, but probing and quantifying such entanglement has long remained experimentally elusive. Here, we use reson…
Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
Inelastic neutron scattering determination of the spin Hamiltonian for BaCdVO(PO)
V. K. Bhartiya, S. Hayashida, K. Yu. Povarov +4
Single crystal inelastic neutron scattering is used to study spin wave excitations in the fully polarized state of the frustrated quantum ferro-antiferromagnet BaCdVO(PO).…
Origin of magnetic anisotropy in the spin ladder compound (CHN)CuBr
D. Blosser, V. K. Bhartiya, D. J. Voneshen +1
The spin ladder compound (CHN)CuBr (BPCB) is studied by means of high-resolution inelastic neutron scattering. In agreement with previous studies we find…
Thermodynamics of a frustrated quantum magnet on a square lattice
K. Yu. Povarov, V. K. Bhartiya, Z. Yan +1
We report the magnetic and calorimetric measurements in single crystal samples of the square lattice quantum antiferromagnet BaCdVO(PO). An investigation of t…
Quantum Critical Dynamics in a Spin Ladder
D. Blosser, V. K. Bhartiya, D. J. Voneshen +1
By means of inelastic neutron scattering we investigate finite temperature dynamics in the quantum spin ladder compound (CHN)CuBr (BPCB) near the magnetic field…
Superconductivity model for a spin-vortex checkerboard
Anastasia V. Aristova, Vivek K. Bhartiya, Boris V. Fine
We introduce a microscopic model aimed at describing the behavior of fermionic excitations in the background of a magnetic texture called "spin-vortex checkerboard". This texture w…
