Three Lectures on Chiral Symmetry
N. D. Hari Dass
In these lectures I cover various aspects of Chiral Symmetry in the hadronic world from a pre-QCD perspective. I also discuss the absence of spontaneous symmetry breaking in d=4 la…
An alternate model for protective measurements of two-level systems
Anirban Das, N. D. Hari Dass
In this article we propose an alternate model for the so called {\it protective measurements}, more appropriately {\it adiabatic measurements} of a spin 1/2 system where the {\it a…
Purifications Without Entanglement, State Reconstructions and Entropy
Chirag Dhara, N. D. Hari Dass
In this paper we have analysed in detail two different purification protocols. The first one, proposed by Sudarshan, is based on the preservation of probabilities.We have construct…
Purification of Single Qubits and reconstruction from Post-Measurement State
Chirag Dhara, N. D. Hari Dass
Purification of mixed states in Quantum Mechanics, by which we mean the transformation into pure states, has been viewed as an {\it Operation} in the sense of Kraus et al and expli…
