Correlated Metals, Metamagnetism, and Orbital Nematic Order in moiré Materials with Neural Quantum States
Wei Zhang, Ataç İmamoğlu, Tao Shi +2
In this work, we investigate a continuum model of two-dimensional electrons interacting via long-range Coulomb forces and subject to a triangular periodic potential at filling fact…
Universal magnetic energy scale in the doped Fermi-Hubbard model
Radu Andrei, Ivan Morera, Jonathan B. Curtis +2
Magnetic correlations of doped Mott insulators hold the key to the unusual characteristics of many quantum materials. Recent experiments with ultracold atoms in optical lattices ha…
Fractionalization from Kinetic Frustration in Doped Two-Dimensional SU(4) Quantum Magnets
Wilhelm Kadow, Ivan Morera, Eugene Demler +1
Separating electrons into emergent fractional quasiparticles is a hallmark of exotic quantum phases of matter with strong interactions. Understanding under which circumstances frac…
Two-dimensional spectroscopy of bosonic collective excitations in disordered many-body systems
Alex Gómez Salvador, Ivan Morera, Marios H. Michael +5
We present a novel theoretical approach for computing and analyzing two-dimensional spectroscopy of bosonic collective excitations in disordered many-body systems. Specifically, we…
Itinerant magnetism and magnetic polarons in the triangular lattice Hubbard model
Ivan Morera, Eugene Demler
We use density matrix renormalization group to investigate the phase diagram of the Fermi Hubbard model on a triangular lattice with densities above half-filling, . W…
Kinetic Magnetism in Triangular Moiré Materials
Livio Ciorciaro, Tomasz Smolenski, Ivan Morera +8
Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly correlated materials such as cuprates originate from Coulomb exchange interactions. The…
High-temperature kinetic magnetism in triangular lattices
Ivan Morera, Márton Kanász-Nagy, Tomasz Smolenski +3
We study kinetic magnetism for the Fermi-Hubbard models in triangular type lattices, including a zigzag ladder, four- and six-legged triangular cylinders and a full two-dimensional…
