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…
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…
Superconductivity and Chiral Symmetry Breaking with Fermion Clusters
Shailesh Chandrasekharan
Cluster variables have recently revolutionized numerical work in certain models involving fermionic variables. This novel representation of fermionic partition functions is continu…
Novel Quantum Monte Carlo Algorithms for Fermions
Shailesh Chandrasekharan
Recent research shows that the partition function for a class of models involving fermions can be written as a statistical mechanics of clusters with positive definite weights. Thi…
