Breakdown of the thermodynamic limit in quantum spin and dimer models
Jeet Shah, Laura Shou, Jeremy Shuler +1
The thermodynamic limit is foundational to statistical mechanics, underlying our understanding of many-body phases. It assumes that, as the system size grows infinitely at fixed de…
Exactly Solvable Topological Phase Transition in a Quantum Dimer Model
Laura Shou, Jeet Shah, Matthew Lerner-Brecher +3
We consider a family of generalized Rokhsar-Kivelson (RK) Hamiltonians, which are reverse-engineered to have an arbitrary edge-weighted superposition of dimer coverings as their ex…
Instability of steady-state mixed-state symmetry-protected topological order to strong-to-weak spontaneous symmetry breaking
Jeet Shah, Christopher Fechisin, Yu-Xin Wang +6
Recent experimental progress in controlling open quantum systems enables the pursuit of mixed-state nonequilibrium quantum phases. We investigate whether open quantum systems hosti…
A quantum monomer-dimer model on Penrose tilings
Jeet Shah, Gautam Nambiar, Alexey V. Gorshkov +1
We define a quantum monomer-dimer model in the space of maximal dimer coverings of quasicrystalline Penrose tilings. Since Penrose tilings do not admit perfect dimer coverings, as…
