XDiag: Exact Diagonalization for Quantum Many-Body Systems
Alexander Wietek, Luke Staszewski, Martin Ulaga +6
Exact diagonalization (ED) is a cornerstone technique in quantum many-body physics, enabling precise solutions to the Schrödinger equation for interacting quantum systems. Despite…
The source of hardware-tailored codes and coding phases
Gaurav Gyawali, Henry Shackleton, Zhu-Xi Luo +1
A central challenge in quantum error correction is identifying powerful quantum codes tailored to specific hardware and determining their error thresholds above which quantum infor…
Deconfined quantum criticality of nodal -wave superconductivity, Néel order, and charge order on the square lattice at half-filling
Maine Christos, Henry Shackleton, Subir Sachdev +1
We consider a SU(2) lattice gauge theory on the square lattice, with a single fundamental complex fermion and a single fundamental complex boson on each lattice site. Projective sy…
Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Laurel E. Anderson, Antti Laitinen, Andrew Zimmerman +7
Disorder at the etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially-filled Landau levels, providing a potentia…
Sign-problem-free effective models of triangular lattice quantum antiferromagnets
Leyna Shackleton, Subir Sachdev
The triangular lattice antiferromagnet with spins and nearest neighbor interactions is known to have long-range antiferromagnetic order, with nearest-neighbor spins at an a…
Conductance and thermopower fluctuations in interacting quantum dots
Leyna Shackleton, Laurel E. Anderson, Philip Kim +1
We model an interacting quantum dot of electrons by a Hamiltonian with random and all-to-all single particle hopping (of r.m.s. strength ) and two-particle interactions (of r.m.…
