Linked Cluster Series Expansions for Two-Particle Bound States
Weihong Zheng, C. J. Hamer, R. R. P. Singh +2
We develop strong-coupling series expansion methods to study two-particle spectra of quantum lattice models. At the heart of the method lies the calculation of an effective Hamilto…
d-wave resonating valence bond states of fermionic atoms in optical lattices
Simon Trebst, Ulrich Schollwoeck, Matthias Troyer +1
We study controlled generation and measurement of superfluid d-wave resonating valence bond (RVB) states of fermionic atoms in 2D optical lattices. Starting from loading spatial an…
Realizing the Nishimori transition across the error threshold for constant-depth quantum circuits
Edward H. Chen, Guo-Yi Zhu, Ruben Verresen +9
Preparing quantum states across many qubits is necessary to unlock the full potential of quantum computers. However, a key challenge is to realize efficient preparation protocols w…
Two-dimensional quantum liquids from interacting non-Abelian anyons
Andreas W. W. Ludwig, Didier Poilblanc, Simon Trebst +1
A set of localized, non-Abelian anyons - such as vortices in a p_x + i p_y superconductor or quasiholes in certain quantum Hall states - gives rise to a macroscopic degeneracy. Suc…
Decoherence-induced self-dual criticality in topological states of matter
Qingyuan Wang, Romain Vasseur, Simon Trebst +2
Quantum measurements performed on a subsystem of a quantum many-body state can generate entanglement for its remaining constituents. The whole system including the measurement reco…
Spin-valley magnetism on the triangular moiré lattice with SU(4) breaking interactions
Lasse Gresista, Dominik Kiese, Simon Trebst +1
The discovery of correlated insulating states in moiré heterostructures has renewed the interest in strongly-coupled electron systems where spin and valley (or layer) degrees of f…
