Numerical Investigations of Phase Transitions in Lattice Field Theories
Vamika Longia
The study of phase transitions plays an important role in understanding qualitative changes in the behaviour of physical systems at criticality. Despite decades of progress, there…
Configurational Thermometer for Lattice Gauge Theories
Vamika Longia, Navdeep Singh Dhindsa, Anosh Joseph
We propose a diagnostic tool, a temperature estimator, for lattice gauge theory simulations. The estimator is obtained from the gradient and the Hessian of the Euclidean lattice ac…
Gradient and Hessian-Based Temperature Estimator in Lattice Gauge Theories: A Diagnostic Tool for Stability and Consistency in Numerical Simulations
Navdeep Singh Dhindsa, Anosh Joseph, Vamika Longia
We present a field configuration-based temperature estimator in lattice gauge theories, constructed from the gradient and Hessian of the Euclidean action. Adapted from geometric fo…
Phase diagram of generalized XY model using tensor renormalization group
Abhishek Samlodia, Vamika Longia, Raghav G. Jha +1
We use the higher-order tensor renormalization group method to study the two-dimensional generalized XY model that admits integer and half-integer vortices. This model is the defor…
Investigating the Two-Dimensional Generalized XY Model using Tensor Networks
Vamika Longia, Anosh Joseph, Abhishek Samlodia
The critical behavior of the two-dimensional XY model has been explored in the literature using various methods. They include the high-temperature expansion (HTE) method, Monte Car…
