Emergence of Superconductivity in Doped Multiorbital Hubbard Chains
Niravkumar D. Patel, Nitin Kaushal, Alberto Nocera +2
We introduce a variational state for one-dimensional two-orbital Hubbard models that intuitively explains the recent computational discovery of pairing in these systems when hole d…
Magnetic phase transitions in quantum spin-orbital liquids
Shi Feng, Niravkumar D. Patel, Panjin Kim +2
We investigate the spin and orbital correlations of a superexchange model with spin and orbital relevant for transition metal Mott insulators, using exact diagon…
Two-Magnon Bound States in the Kitaev Model in a -Field
Subhasree Pradhan, Niravkumar D. Patel, Nandini Trivedi
It is now well established that the Kitaev honeycomb model in a magnetic field along the -direction harbors an intermediate gapless quantum spin liquid (QSL) phase sandwiche…
Targeting Multiple States in the Density Matrix Renormalization Group with The Singular Value Decomposition
E. F. D'Azevedo, W. R. Elwasif, N. D. Patel +1
In the Density Matrix Renormalization Group (DMRG), multiple states must be included in the density matrix when properties beyond ground state are needed, including temperature dep…
Magnetic field induced intermediate quantum spin-liquid with a spinon Fermi surface
Niravkumar D. Patel, Nandini Trivedi
The Kitaev model with an applied magnetic field in the direction shows two transitions: from a non-abelian gapped quantum spin liquid (QSL) to a gapless QSL at $H_{c1} \…
Novel Magnetic Block States in Low-Dimensional Iron-Based Superconductors
J. Herbrych, J. Heverhagen, N. D. Patel +4
Inelastic neutron scattering recently confirmed the theoretical prediction of a -magnetic state along the legs of quasi-one-dimensional (quasi…
