Mott transition, magnetic and orbital orders in the ground state of the two-band Hubbard model using variational slave-spin mean field formalism
Arun Kumar Maurya, Md. Tahir Hossain Sarder, Amal Medhi
We study the ground state of the Hubbard model on a square lattice with two degenerate orbitals per site and at integer fillings as a function of onsite Hubbard repulsion and H…
Crucial role of Internal Collective Modes in Underdoped Cuprates
Aabhaas V. Mallik, Umesh K. Yadav, Amal Medhi +2
The enigmatic cuprate superconductors have attracted resurgent interest with several recent reports and discussions of competing orders in the underdoped side. Motivated by this, h…
Feasibility of a metamagnetic transition in correlated systems
Swagata Acharya, Amal Medhi, N. S. Vidhyadhiraja +1
The long-standing issue of the competition between the magnetic field and the Kondo effect, favoring, respectively, triplet and singlet ground states is addressed using a cluster s…
Synchronous and Asynchronous Mott Transitions in Topological Insulator Ribbons
Amal Medhi, Vijay B. Shenoy, H. R. Krishnamurthy
We address how the nature of linearly dispersing edge states of two dimensional (2D) topological insulators evolves with increasing electron-electron correlation engendered by a Hu…
