ITAMP Topical Lunch Discussion
Date: FRIDAY, January 31
Time: 12:00-1:30 pm
Pizza will be served.
Location: B-106 @ Center for Astrophysics (60 Garden Street)
Directions: after entering the lobby of the CfA, turn right to enter the
hallway of the B building. In the hallway, turn right again, and B-106 is
there.
Speaker: Arghavan Safavi (MIT)
Title: Using Worm algorithm to study many body physics of dipoles in
layered geometries
Abstract:
The experimental success of trapping polar molecules and atoms with
magnetic dipolar moments allows us to study many body systems where
dipole-dipole interactions are significant. In this talk I will introduce
path integral Quantum Monte Carlo, using the Worm algorithm, and use it to
study the ground state phase diagram of dipolar bosons in a two-dimensional
lattice.
I will then describe how the Worm algorithm can be modified to study
pairing in a bilayer geometry. This extension to the Worm algorithm allows
us to study the many body phases of these pairs.
Finally I will describe the multiworm algorithm, which allows for the
efficient study of chain formation in multilayered geometries. I will show
how one can use this algorithm, in addition to analytical techniques such
as bosonization, to study the physics of a stack of one-dimensional tubes
of dipolar bosons.
