Stroboscopic stability of a Floquet chiral spin liquid beyond the folding frequency
Didier Poilblanc
We study the two-step Floquet dynamics of the chiral -- Heisenberg model on the torus, alternating its non-chiral Heisenberg part and its chiral pl…
Investigation of the - Heisenberg model on the triangular lattice: A study with projected entangled-pair states
Litao Ma, Wei-Lin Tu, Didier Poilblanc +1
The nature of the quantum spin liquid (QSL) phase in the frustrated - Heisenberg model on the triangular lattice remains an open and actively debated problem. In this wor…
Detuning the Floquet anomalous chiral spin liquid
Matthieu Mambrini, Nathan Goldman, Didier Poilblanc
At high-frequency a periodically-driven quantum spin-1/2 system can emulate a chiral spin liquid (CSL) described by an effective static local chiral Hamiltonian. In contrast, at lo…
Simulating Bulk Gap in Chiral Projected Entangled-Pair States
Ji-Yao Chen, Yi Tan, Sylvain Capponi +3
Projected entangled-pair states (PEPS) have proven effective in capturing chiral spin liquid ground states, yet the presence of long-range ``gossamer'' correlation tails raises con…
Simulating chiral spin liquids with fermionic Projected Entangled Paired States
Sasank Budaraju, Didier Poilblanc, Sen Niu
Chiral Spin Liquids (CSL) based on spin-1/2 fermionic Projected Entangled Pair States (fPEPS) are considered on the square lattice. First, fPEPS approximants of Gutzwiller-projecte…
Gauge symmetry of excited states in projected entangled-pair state simulations
Yi Tan, Ji-Yao Chen, Didier Poilblanc +1
While gauge symmetry is a well-established requirement for representing topological orders in projected entangled-pair state (PEPS), its impact on the properties of low-lying excit…
