Isolated flat bands in 2D lattices based on a novel path-exchange symmetry
Jun-Hyung Bae, Tigran Sedrakyan, Saurabh Maiti
The increased ability to engineer two-dimensional (2D) systems, either using materials, photonic lattices, or cold atoms, has led to the search for 2D structures with interesting p…
Collective spin modes in Fermi liquids with spin-orbit coupling
Dmitrii L. Maslov, Abhishek Kumar, Saurabh Maiti
A combination of spin-orbit coupling and electron-electron interaction gives rise to a new type of collective spin modes, which correspond to oscillations of magnetization even in…
Zero-field spin resonance in graphene with proximity-induced spin-orbit coupling
Abhishek Kumar, Saurabh Maiti, Dmitrii L. Maslov
We investigate collective spin excitations in graphene with proximity-induced spin-orbit coupling (SOC) of the Rashba and valley-Zeeman types, as it is the case, e.g., for graphene…
Is the composite fermion state of Graphene a doped Chern insulator?
Saurabh Maiti, Tigran Sedrakyan
Graphene in the presence of a strong external magnetic field is a unique attraction for investigations of the fractional quantum Hall (fQH) states with odd and even denominators of…
Fermionization of Bosons in a Flat Band
Saurabh Maiti, Tigran A. Sedrakyan
Strongly interacting bosons that live in a lattice with degeneracy in its lowest energy band experience frustration that can prevent the formation of a Bose-Einstein condensate. Su…
Intrinsic Damping of Collective Spin Modes in a Two-Dimensional Fermi Liquid with Spin-Orbit Coupling
Saurabh Maiti, Dmitrii L. Maslov
A Fermi liquid with spin-orbit coupling (SOC) is expected to support a new kind of collective modes: oscillations of magnetization in the absence of the magnetic field. We show tha…
Electronic transport in the Coulomb phase of the pyrochlore spin ice
Gia-Wei Chern, Saurabh Maiti, Rafael M. Fernandes +1
We investigate the transport properties of itinerant electrons interacting with a background of localized spins in a correlated paramagnetic phase of the pyrochlore lattice. We fin…
Optical Integral and Sum Rule Violation
Saurabh Maiti, Andrey V. Chubukov
The purpose of this work is to investigate the role of the lattice in the optical Kubo sum rule in the cuprates. We compute conductivities, optical integrals W, and ΔW between supe…
