Emergent Half Metal at Finite Temperatures in a Mott Insulator
Gour Jana, Abhishek Joshi, Subhajyoti Pal +1
Sustaining exotic quantum mechanical phases at high temperatures is a long-standing goal of condensed matter physics. Among them, half-metals are spin-polarized conductors that are…
Thermal transitions of the modulated superfluid for spin-orbit coupled correlated bosons in an optical lattice
Arijit Dutta, Abhishek Joshi, K. Sengupta +1
We investigate the thermal physics of a Bose-Hubbard model with Rashba spin-orbit coupling starting from a strong coupling mean-field ground state. The essential role of the spin-o…
The impact of speckle disorder on a superfluid Fermi system
Abhishek Joshi, Pinaki Majumdar
Optical lattice experiments which probe the effect of disorder on superfluidity often use a speckle pattern for generating the disorder. Such speckle disorder is spatially correlat…
Thermal decoherence in a strongly correlated Bose liquid
Abhishek Joshi, Pinaki Majumdar
We compute the single particle spectral function of a Bose liquid on a lattice, at integer filling, close to the superfluid-Mott transition. We use a `static path approximation' th…
Thermal phases of correlated lattice boson: a classical fluctuation theory
Abhishek Joshi, Pinaki Majumdar
We present a method that generalises the standard mean field theory of correlated lattice bosons to include amplitude and phase fluctuations of the field that induces onsite…
