Determinant Quantum-Quantum Monte Carlo: Coherent Auxiliary-Field Sampling
Xuepeng Wang, Sagnik Banerjee, Debanjan Chowdhury
We introduce determinant quantum-quantum Monte Carlo (DQMC), a quantum algorithm that lifts the auxiliary-field sampling and averaging at the operational core of determinant qu…
Intertwined Orders, Quantum Criticality and Skyrmions in Tunable Topological Bands
Xuepeng Wang, Johannes S. Hofmann, Debanjan Chowdhury
Skyrmions are emergent many-body excitations that lie at the heart of both multi-component quantum Hall-like systems and deconfined quantum criticality. In a companion article (X.…
Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
The study of interacting topological bands with a tunable bandwidth offers a unique platform to study the interplay of intertwined orders and emergent non-electronic excitations. H…
Gaplessness from disorder and quantum geometry in gapped superconductors
Omri Lesser, Sagnik Banerjee, Xuepeng Wang +3
It is well known that disorder can induce low-energy Andreev bound states in a sign-changing, but fully gapped, superconductor at junctions. Generically, these excitations are…
Theory of Correlated Insulators and Superconductor at in Twisted WSe
Sunghoon Kim, Juan Felipe Mendez-Valderrama, Xuepeng Wang +1
The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of in bilayers of twisted W…
Intertwined Magnetism and Superconductivity in Isolated Correlated Flat Bands
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
Multi-orbital electronic models hosting a non-trivial band-topology in the regime of strong electronic interactions are an ideal playground for exploring a host of complex phenomen…
Interaction-mitigated Landau damping
Xuepeng Wang, Roderich Moessner, Debanjan Chowdhury
Bosonic collective modes are ubiquitous in metals, but over a wide range of energy and momenta suffer from Landau damping, decaying into the continuum of particle-hole excitations.…
