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…
Quasi two-dimensional magnetism in spin- square lattice compound Cu[CH(COO)][HN-(CH)-NH]3HO
S. Guchhait, S. Baby, M. Padmanabhan +2
We report the crystal growth and structural and magnetic properties of quasi two-dimensional quantum magnet Cu[CH(COO)][HN-(CH)-NH]3H…
Intrinsically high thermoelectric figure of merit of half-Heusler ZrRuTe
Sonu Prasad Keshri, Amal Medhi
The electronic structure and thermoelectric properties of ZrRuTe-based Half-Heusler compounds are studied using density functional theory (DFT) and Boltzmann transport formalism. B…
A case study of bilayered spin- square lattice compound [VO(HCOO)(HO)]
S. Guchhait, U. Arjun, P. K. Anjana +9
We present the synthesis and a detail investigation of structural and magnetic properties of polycrystalline [VO(HCOO)(HO)] by means of x-ray diffraction, magnetic sus…
Role of curvature and domain shape on Turing patterns
Sankaran Nampoothiri, Amal Medhi
We consider pattern formation using reaction-diffusion equation on various non-uniformly curved surfaces. We explore how, in general, curvature and, in particular the domain shape…
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…
Sensory organ like response determines the magnetism of zigzag-edged honeycomb nanoribbons
Somnath Bhowmick, Amal Medhi, Vijay B. Shenoy
We present an analytical theory for the magnetic phase diagram for zigzag edge terminated honeycomb nanoribbons described by a Hubbard model with an interaction parameter U . We sh…
Fermionic Superfluid from a Bilayer Band Insulator in an Optical Lattice
Yogeshwar Prasad, Amal Medhi, Vijay B. Shenoy
We propose a model to realize a fermionic superfluid state in an optical lattice circumventing the cooling problem. Our proposal exploits the idea of tuning the interaction in a ch…
Continuum Theory of Edge States of Topological Insulators: Variational Principle and Boundary Conditions
Amal Medhi, Vijay B. Shenoy
We develop a continuum theory to model low energy excitations of a generic four-band time reversal invariant electronic system with boundaries. We propose a variational energy func…
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…
Coexistence of magnetism and superconductivity in a t-J bilayer
Amal Medhi, Saurabh Basu, C. Y. Kadolkar
We investigate coexistence of antiferromagnetic and superconducting correlations in bilayered materials using a two-dimensional t-J model with couplings across the layers using var…
