Rotor Spectra, Berry Phases, and Monopole Fields: from Antiferromagnets to QCD
S. Chandrasekharan, F. -J. Jiang, M. Pepe +1
The order parameter of a finite system with a spontaneously broken continuous global symmetry acts as a quantum mechanical rotor. Both antiferromagnets with a spontaneously broken…
Effects of the anomaly on the QCD chiral phase transition
Shailesh Chandrasekharan, Abhijit C. Mehta
We study a lattice field theory described by two flavors of massless staggered fermions interacting with U(1) gauge fields in the strong coupling limit. We show that the lattice mo…
Disorder-Induced Superfluidity in Hardcore Bosons in Two Dimensions
Ji-Woo Lee, Shailesh Chandrasekharan, Harold U. Baranger
We study the effect of disorder on hardcore bosons in two dimensions at the SU(2) symmetric ``Heisenberg point''. We obtain our results with quantum Monte Carlo simulations using t…
Anomalous superfluidity in 2+1 dimensional two-color lattice QCD
Shailesh Chandrasekharan
We study thermodynamics of strongly coupled lattice QCD with colors of staggered fermions in dimensions. The partition function of this model can be written elegantly…
Quantum Phase Transitions of Hard-Core Bosons in Background Potentials
Anand Priyadarshee, Shailesh Chandrasekharan, Ji-Woo Lee +1
We study the zero temperature phase diagram of hard core bosons in two dimensions subjected to three types of background potentials: staggered, uniform, and random. In all three ca…
Spectroscopy of the Kondo Problem in a Box
Ribhu K. Kaul, Gergely Zaránd, Shailesh Chandrasekharan +2
Motivated by experiments on double quantum dots, we study the problem of a single magnetic impurity confined in a finite metallic host. We prove an exact theorem for the ground sta…
