TLDR

Possible ferro-spin nematic order in NiGa2S4

- S. Bhattacharjee, V. Shenoy, T. Senthil
- Physics
- 10 May 2006

We explore the possibility that the spin-1 triangular lattice magnet NiGa2S4 may have a ferronematic ground state with no frozen magnetic moment but a uniform quadrupole moment. Such a state may be… Expand

Temperature Dependence of the Butterfly Effect in a Classical Many-Body System.

TLDR

Quantum phase transition in Heisenberg-Kitaev model

- R. Schaffer, S. Bhattacharjee, Yong Baek Kim
- Physics
- 25 June 2012

We explore the nature of the quantum phase transition between a magnetically ordered state with collinear spin pattern and a gapless $Z_2$ spin liquid in the Heisenberg-Kitaev model. We construct a… Expand

Interplay of Magnetism and Topological Superconductivity in Bilayer Kagome Metals.

Bosonic integer quantum Hall effect in an interacting lattice model.

- Yin-chen He, S. Bhattacharjee, R. Moessner, F. Pollmann
- PhysicsPhysical review letters
- 4 June 2015

We study a bosonic model with correlated hopping on a honeycomb lattice, and show that its ground state is a bosonic integer quantum Hall (BIQH) phase, a prominent example of a symmetry-protected… Expand

Tuning of dielectric properties and magnetism of SrTiO(3) by site-specific doping of Mn

- D. Choudhury, S. Mukherjee,
+12 authors D. Sarma - Materials Science
- 24 September 2010

Combining experiments with first-principles calculations, we show that site-specific doping of Mn into SrTiO(3) has a decisive influence on the dielectric properties of these doped systems. We find… Expand

Dynamics of a quantum spin liquid beyond integrability: The Kitaev-Heisenberg-Γ model in an augmented parton mean-field theory

- J. Knolle, S. Bhattacharjee, R. Moessner
- Physics
- 11 January 2018

We present an augmented parton mean-field theory which (i) reproduces the $exact$ ground state, spectrum, and dynamics of the quantum spin liquid phase of Kitaev's honeycomb model; and (ii) is… Expand

Z 2 topological liquid of hard-core bosons on a kagome lattice at 1 / 3 filling

- K. Roychowdhury, S. Bhattacharjee, F. Pollmann
- Physics
- 22 May 2015

We consider hard-core bosons on the kagome lattice in the presence of short-range repulsive interactions and focus particularly on the filling factor $1/3$. In the strongly interacting limit, the… Expand

Tunneling conductance of graphene NIS junctions.

- S. Bhattacharjee, K. Sengupta
- PhysicsPhysical review letters
- 19 July 2006

We show that, in contrast with conventional normal metal-insulator-superconductor (NIS) junctions, the tunneling conductance of a NIS junction in graphene is an oscillatory function of the effective… Expand
