Chiral limit of 2-color QCD at strong couplings
Shailesh Chandrasekharan, Fu-Jiun Jiang
We study two-color lattice QCD with massless staggered fermions in the strong coupling limit using a new and efficient cluster algorithm. We focus on the phase diagram of the model…
On the Sign Problem in the Hirsch-Fye Algorithm for Impurity Problems
Jaebeom Yoo, Shailesh Chandrasekharan, Ribhu K. Kaul +2
We show that there is no fermion sign problem in the Hirsch and Fye algorithm for the single-impurity Anderson model. Beyond the particle-hole symmetric case for which a simple pro…
Cluster Algorithms for Quantum Impurity Models and Mesoscopic Kondo Physics
Jaebeom Yoo, Shailesh Chandrasekharan, Ribhu K. Kaul +2
Nanoscale physics and dynamical mean field theory have both generated increased interest in complex quantum impurity problems and so have focused attention on the need for flexible…
Quantum Monte Carlo Study of Disordered Fermions
Ji-Woo Lee, Shailesh Chandrasekharan, Harold U. Baranger
We study a strongly correlated fermionic model with attractive interactions in the presence of disorder in two spatial dimensions. Our model has been designed so that it can be sol…
Mesoscopic Kondo Problem
Ribhu K. Kaul, Denis Ullmo, Shailesh Chandrasekharan +1
We study the effect of mesoscopic fluctuations on a magnetic impurity coupled to a spatially confined electron gas with a temperature in the mesoscopic range (i.e. between the mean…
