Onset of Quantum Chaos and Ergodicity in Spin Systems with Highly Degenerate Hilbert Spaces
Mahmoud Abdelshafy, Rubem Mondaini, Marcos Rigol
We show that in systems with highly degenerate energy spectra, such as the 2D transverse-field Ising model (2DTFIM) in the strong-field limit, quantum chaos can emerge in finite sy…

Numerical linked-cluster expansions for two-dimensional spin models with continuous disorder distributions
Mahmoud Abdelshafy, Marcos Rigol
We show that numerical linked cluster expansions (NLCEs) based on sufficiently large building blocks allow one to obtain accurate low-temperature results for the thermodynamic prop…

Kaleidoscope of exotic quantum phases in a frustrated XY model
Christopher N. Varney, Kai Sun, Victor Galitski +1
The existence of quantum spin liquids was first conjectured by Pomeranchuk some 70 years ago, who argued that frustration in simple antiferromagnetic theories could result in a Fer…
