D-Theory: Field Quantization by Dimensional Reduction of Discrete Variables
R. Brower, S. Chandrasekharan, S. Riederer +1
D-theory is an alternative non-perturbative approach to quantum field theory formulated in terms of discrete quantized variables instead of classical fields. Classical scalar field…
Lattice Theories with Nonlinearly Realized Chiral Symmetry
S. Chandrasekharan, M. Pepe, F. D. Steffen +1
We present the lattice formulation of effective Lagrangians in which chiral symmetry is realized nonlinearly on the fermion fields. In this framework both the Wilson term removing…
Chiral and Critical Behavior in Strong Coupling QCD
Shailesh Chandrasekharan
We use a cluster algorithm to study the critical behavior of strongly coupled lattice QCD in the chiral limit. We show that the finite temperature chiral phase transition belongs t…
Chiral Limit of Strongly Coupled Lattice QCD at Finite Temperatures
Shailesh Chandrasekharan, Fu-Jiun Jiang
We use the recently proposed directed-path algorithm to study the chiral limit of strongly coupled lattice QCD with staggered quarks at finite temperatures. The new algorithm allow…
Kosterlitz Thouless Universality in Dimer Models
Shailesh Chandrasekharan, Costas G. Strouthos
Using the monomer-dimer representation of strongly coupled U(N) lattice gauge theories with staggered fermions, we study finite temperature chiral phase transitions in (2+1) dimens…
Nonlinear Realization of Chiral Symmetry on the Lattice
S. Chandrasekharan, M. Pepe, F. D. Steffen +1
We formulate lattice theories in which chiral symmetry is realized nonlinearly on the fermion fields. In this framework the fermion mass term does not break chiral symmetry. This p…
Chiral Limit of Strongly Coupled Lattice Gauge Theories
David H. Adams, Shailesh Chandrasekharan
We construct a new and efficient cluster algorithm for updating strongly coupled U(N) lattice gauge theories with staggered fermions in the chiral limit. The algorithm uses the con…
QCD at Fixed Topology
R. Brower, S. Chandrasekharan, J. Negele +1
Since present Monte Carlo algorithms for lattice QCD may become trapped in a fixed topological charge sector, it is important to understand the effect of calculating at fixed topol…
