A long-range model for the electron-nuclear coupling and two-stage order in TmVO
Sayan Ghosh, Anirudha Menon, Manoranjan Kumar +1
We study an infinite-range coupled electronic-quadrupole and nuclear-spin model for ferro-quadrupolar and nuclear-spin ordering in TmVO in external magnetic and strain fields.…
Frustrated spin-1/2 Heisenberg model on a Kagome-strip chain: Dimerization and mapping to a spin-orbital Kugel-Khomskii model
Sayan Ghosh, Rajiv R. P. Singh, Manoranjan Kumar
We investigate the quantum phases of a frustrated antiferromagnetic Heisenberg spin-1/2 model Hamiltonian on a Kagome-strip chain (KSC), a one-dimensional analogue of the Kagome la…
Quantum Criticality in the infinite-range Transverse Field Ising Model
Nicholas Curro, Kaeshav Danesh, Rajiv R. P. Singh
We study quantum criticality in the infinite range Transverse-Field Ising Model. We find subtle differences with respect to the well-known single-site mean-field theory, especially…
Competing Gauge Fields and Entropically-Driven Spin Liquid to Spin Liquid Transition in non-Kramers Pyrochlores
Daniel Lozano-Gómez, Vincent Noculak, Jaan Oitmaa +4
Gauge theories are powerful tools in theoretical physics, allowing complex phenomena to be reduced to simple principles, and are used in both high-energy and condensed matter physi…
High-temperature magnetization and entropy of the triangular lattice Hubbard model in a Zeeman field
Owen Bradley, Yutan Zhang, Jaan Oitmaa +1
We use strong coupling expansions to calculate the entropy function , the magnetization , and the double occupancy factor for the half-filled triangular la…
Classical and quantum phases of the pyrochlore magnet with Heisenberg and Dzyaloshinskii-Moriya interactions
Vincent Noculak, Daniel Lozano-Gómez, Jaan Oitmaa +4
We investigate the ground state and critical temperature phase diagrams of the classical and quantum pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-…
