Chiral Bosonic Topological Insulator on the Honeycomb Lattice with Anisotropic Interactions
Amrita Ghosh, Eytan Grosfeld
We study hard-core bosons on the honeycomb lattice in the presence of anisotropic nearest-neighbor repulsive interactions. Using a quantum Monte Carlo (QMC) technique, we extract t…
Weak topological insulating phases of hard-core-bosons on the honeycomb lattice
Amrita Ghosh, Eytan Grosfeld
We study the phases of hard-core-bosons on a two-dimensional periodic honeycomb lattice in the presence of an on-site potential with alternating sign along the different y-layers o…
Lp-strong solution to fluid-rigid body interaction system with Navier slip boundary condition
Hind Al Baba, Amrita Ghosh, Boris Muha +1
We study a fluid-structure interaction problem describing movement of a rigid body inside a bounded domain filled by a viscous fluid. The fluid is modelled by the generalized incom…
Unique continuation for a non bi-Laplacian fourth order elliptic operator
Amrita Ghosh, Tuhin Ghosh
This paper discusses the unique continuation principal of the solutions of the following perturbed fourth order elliptic differential operator , where \[ \mat…
Mixed-order transition and tricritical point associated with checkerboard supersolidity in the two-dimensional model
Amrita Ghosh, Satyaki Kar, Sudhakar Yarlagadda
We use Quantum Monte Carlo method employing stochastic-series-expansion technique to study the ground state properties of the model on a square lattice. We find that, awa…
Semigroup theory for the Stokes operator with Navier boundary condition on spaces
Cherif Amrouche, Miguel Escobedo, Amrita Ghosh
We consider the incompressible Navier-Stokes equations in a bounded domain with boundary, completed with slip boundary condition. Apart from studying the genera…
Homogenization for non-local elliptic operators in both perforated and non-perforated domains
Loredana Balilescu, Amrita Ghosh, Tuhin Ghosh
In this paper, we focus on the homogenization process of the non-local elliptic boundary value problem $$\mathcal{L}_\varepsilon^s u_\varepsilon =(-\nabla\cdot (A_\varepsilon(x)\na…
Uniform estimate for elliptic operator with Robin boundary condition in domain
Cherif Amrouche, Carlos Conca, Amrita Ghosh +1
We consider the Robin boundary value problem in , domain, with $(A \nabla u - \mathbf{f})\cdot \mathbf{n}…
Stokes and Navier-Stokes equations with Navier boundary condition
Paul Acevedo, Cherif Amrouche, Carlos Conca +1
We study the stationary Stokes and Navier-Stokes equations with non-homogeneous Navier boundary condition in a bounded domain of class .…
Study of long-range orders of hard-core bosons coupled to cooperative normal modes in two-dimensional lattices
Amrita Ghosh, Sudhakar Yarlagadda
Understanding the microscopic mechanism of coexisting long-range orders (such as lattice supersolidity) in strongly correlated systems is a subject of immense interest. We study th…
