Excitonic Stripe Order in the Two-Orbital Hubbard-Kanamori Model
Rafael D. Soares, Luke Staszewski, Chunhan Feng +1
Excitonic condensation and stripe formation are two distinct manifestations of electronic correlations. While excitonic order naturally arises in multi-orbital systems, stripe orde…
Tunable Magnetic Order in Chiral Coupled Spin Chains
Rafael D. Soares, J. M. Viana Parente Lopes, Hugo Terças
We obtain the ground-state phase diagram of two spin chains consisting in a set two-level systems asymmetrically coupled to an XX chain through a chiral interaction. The interactio…
Ab initio spin Hamiltonians and magnetism of Ce and Yb triangular-lattice compounds
Leonid V. Pourovskii, Rafael D. Soares, Alexander Wietek
We calculate the crystal-field splitting, ground-state Kramers doublet and intersite exchange interactions within the ground-state doublet manifold using an ab initio Hubbard-I bas…
Dissipative phase transition of interacting non-reciprocal fermions
Rafael D. Soares, Matteo Brunelli, Marco Schirò
While non-reciprocal couplings are ubiquitous in classical systems, their impact on quantum many-body criticality and entanglement remains largely unexplored. Using exact numerical…
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…
Symmetries, Conservation Laws and Entanglement in Non-Hermitian Fermionic Lattices
Rafael D. Soares, Youenn Le Gal, Chun Y. Leung +3
Non-Hermitian quantum many-body systems feature steady-state entanglement transitions driven by the competition between unitary dynamics and dissipation. In this work, we reveal th…
Entanglement Transition due to particle losses in a monitored fermionic chain
Rafael D. Soares, Youenn Le Gal, Marco Schirò
Recently, there has been interest in the dynamics of monitored quantum systems using linear jump operators related to the creation or annihilation of particles. Here, we study the…
Non-Unitary Quantum Many-Body Dynamics using the Faber Polynomial Method
Rafael D. Soares, Marco Schirò
Efficient numerical methods are still lacking to probe the unconventional dynamics of quantum many-body systems under non-unitary evolution. In this work, we use Faber polynomials…
Electron-mediated entanglement of two distant macroscopic ferromagnets within a nonequilibrium spintronic device
A. Suresh, R. D. Soares, P. Mondal +6
Using the nascent concept of quantum spin-transfer torque [A. Zholud et al., Phys. Rev. Lett. {\bf 119}, 257201 (2017); M. D. Petrović {\em et al.}, Phys. Rev. X {\bf 11}, 021062 (…
