Complexity and information geometry in spin chains
Nitesh Jaiswal, Mamta Gautam, Tapobrata Sarkar
We study Nielsen complexity and Fubini-Study complexity for a class of exactly solvable one dimensional spin systems. Our examples include the transverse XY spin chain and its natu…
Information Geometry in Time Dependent Quantum Systems and the Geometric Phase
Anshuman Dey, Suvankar Paul, Pratim Roy +1
We study information theoretic geometry in time dependent quantum mechanical systems. First, we discuss global properties of the parameter manifold for two level systems exemplifie…
Information Geometry and the Renormalization Group
Reevu Maity, Subhash Mahapatra, Tapobrata Sarkar
Information theoretic geometry near critical points in classical and quantum systems is well understood for exactly solvable systems. Here we show that renormalization group flow e…
Geodesics in Information Geometry : Classical and Quantum Phase Transitions
Prashant Kumar, Subhash Mahapatra, Prabwal Phukon +1
We study geodesics on the parameter manifold, for systems exhibiting second order classical and quantum phase transitions. The coupled non-linear geodesic equations are solved nume…
Information Geometry and Quantum Phase Transitions in the Dicke Model
Anshuman Dey, Subhash Mahapatra, Pratim Roy +1
We study information geometry of the Dicke model, in the thermodynamic limit. The scalar curvature of the Riemannian metric tensor induced on the parameter space of the model i…
Directed Random Walks on Colored, Periodic Lattices: A Gauge Theoretic Approach
Subhash Mahapatra, Prabwal Phukon, Tapobrata Sarkar
We define a random walk problem which admits analytic results, on a class of infinite periodic lattices which are directed and colored. Our approach is motivated from the fact that…
