Electronic Green's function across the pseudogap to stripe transition in the -- model
Martin Ulaga, Aritra Sinha, Alexander Wietek
Superconducting domes in strongly correlated electronic systems are often accompanied by charge density waves and peculiar features in the electronic structure. The appearance of a…
Evolution of superconductivity from charge clusters to stripes in the -- model
Aritra Sinha, Hannes Karlsson, Martin Ulaga +1
Competition and coexistence of charge orders and superconductivity are hallmarks in many strongly correlated electron systems. Here, we unravel the precise role of charge fluctuati…
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…
Observation of emergent scaling of spin-charge correlations at the onset of the pseudogap
Thomas Chalopin, Petar BojoviÄ, Si Wang +12
In strongly correlated materials, interacting electrons are entangled and form collective quantum states, resulting in rich low-temperature phase diagrams. Notable examples include…
Forestalled Phase Separation as the Precursor to Stripe Order
Aritra Sinha, Alexander Wietek
Stripe order is a prominent feature in the phase diagram of the high-temperature cuprate superconductors. It has been confirmed as the lowest-energy state of the two-dimensional Fe…
