Coupling quantum spin ice to matter on the centered pyrochlore lattice
Rajah P. Nutakki, Sylvain Capponi, Ludovic D. C. Jaubert +1
The low-energy physics of quantum spin ice is known to support an emergent form of quantum electrodynamics (QED), where magnetic monopoles exist and the fine structure constant is…
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…
Classical and quantum spin liquids
Sylvain Capponi
When considering magnetic systems in the thermodynamic limit and at low enough temperature, one finds typically magnetically ordered phases. In contrast, in the high-temperature re…
Evidence for a Dirac spin liquid in the generalized Shastry-Sutherland model
Atanu Maity, Francesco Ferrari, Sylvain Capponi +8
We present a multimethod investigation of the recently reported quantum spin liquid (QSL) phase in the spin-1/2 Heisenberg antiferromagnet on the Shastry-Sutherland lattice. A comp…
A generalized perspective on non-perturbative linked cluster expansions
K. Coester, S. Clever, F. Herbst +2
We identify a fundamental challenge for non-perturbative linked cluster expansions (NLCEs) resulting from the reduced symmetry on graphs, most importantly the breaking of translati…
Competing orders in one-dimensional half-filled multicomponent fermionic cold atoms: The Haldane-charge conjecture
H. Nonne, P. Lecheminant, S. Capponi +2
We investigate the nature of the Mott-insulating phases of half-filled 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of conformal field…
Competing orders in the generalized Hund chain model at half-filling
H. Nonne, E. Boulat, S. Capponi +1
By using a combination of several non-perturbative techniques -- a one-dimensional field theoretical approach together with numerical simulations using density matrix renormalizati…
Haldane charge conjecture in one-dimensional multicomponent fermionic cold atoms
H. Nonne, P. Lecheminant, S. Capponi +2
A Haldane conjecture is revealed for spin-singlet charge modes in 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of a low-energy approach…
Molecular superfluid phase in systems of one-dimensional multicomponent fermionic cold atoms
S. Capponi, G. Roux, P. Lecheminant +3
We study a simple model of N-component fermions with contact interactions which describes fermionic atoms with N=2F+1 hyperfine states loaded into a one-dimensional optical lattice…
Recent progress in the truncated Lanczos method : application to hole-doped spin ladders
O. Chiappa, S. Capponi, D. Poilblanc
The truncated Lanczos method using a variational scheme based on Hilbert space reduction as well as a local basis change is re-examined. The energy is extrapolated as a power law f…
Numerical Calculations of the B1g Raman Spectrum of the Two-Dimensional Heisenberg Model
A. W. Sandvik, S. Capponi, D. Poilblanc +1
The B1g Raman spectrum of the two-dimensional S=1/2 Heisenberg model is discussed within Loudon-Fleury theory at both zero and finite temperature. The exact T=0 spectrum for lattic…

S. Capponi, D. Poilblanc, E. Arrigoni
The single-particle hopping between two chains is investigated by exact-diagonalizations techniques supplemented by finite-size scaling analysis. In the case of two coupled strongl…
