Intracavity THz generation using a thin lithium niobate plate in a compact Kerr-lens mode-locked Yb:CALGO bulk oscillator
Mohsen Khalili, Jokūbas Pimpė, Yicheng Wang +5
We demonstrate intracavity terahertz (THz) generation via optical rectification in a 50-m-thick lithium niobate crystal placed inside a compact diode-pumped Kerr-lens mode-locked (…
Hidden symmetry at the diabolical points of a biaxial spin
Shadan Ghassemi Tabrizi
The paper analyzes a biaxial spin Hamiltonian by mapping it to a finite tight‑binding chain, showing that exact degeneracies (diabolical points) arise where the applied field effec…
GPU-accelerated finite-temperature Lanczos method for Heisenberg spin systems with non-Abelian permutation symmetries
Shadan Ghassemi Tabrizi, Thomas D. Kühne
We extend a recent GPU implementation of the finite-temperature Lanczos method (FTLM) for Heisenberg spin Hamiltonians, which uses only total-magnetization symmetry, to the full pe…
GPU-accelerated finite-temperature Lanczos method for spin Hamiltonians
Shadan Ghassemi Tabrizi, Thomas D. Kühne
We present a GPU implementation of the finite-temperature Lanczos method (FTLM) for Heisenberg spin Hamiltonians that targets workstation hardware rather than distributed-memory cl…
SCF framework, HF stability and RPA correlation for Jordan-Wigner-transformed spin Hamiltonians on arbitrary coupling topologies
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Mapping spins to fermions via the Jordan-Wigner (JW) transformation can render mean-field (Hartree-Fock, HF) descriptions effective for strongly correlated spin systems. As establi…
Scalable implementations of mean-field and correlation methods based on Lie-algebraic similarity transformation of spin Hamiltonians in the Jordan-Wigner representation
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Recent work has highlighted that the strong correlation inherent in spin Hamiltonians can be effectively reduced by mapping spins to fermions via the Jordan-Wigner transformation (…
