N/Z dependence of balance energy throughout the colliding geometries
We study the N/Z dependence of balance energy throughout the mass range for colliding geometry varying from central to peripheral ones. Our results indicate that balance energy decreases linearly with increase in N/Z ratio for all the masses throughout the colliding geometry range. Also, the N/Z dependence of balance energy is sensitive to symmetry energy.

Study of participant-spectator matter and thermalization in isospin asymmetric systems
We study the behavior of participant and spectator matter and thermalization in neutron rich systems at the energy of vanishing flow. Our study indicates that participant-spectator matter follows a similar behavior for neutron-rich systems and for systems lie on the stability line.

Dependence of balance energy on isospin degrees of freedom
Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of 58Ni+58Ni and 58Fe+58Fe as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) colliding geometries.

Role of colliding geometry on the N/Z dependence of balance energy
We study the role of colliding geometry on the N/Z dependence of balance energy using isospin-dependent quantum molecular dynamics model. Our study reveals that the N/Z dependence of balance energy becomes much steeper for peripheral collisions as compared to the central collisions. We also study the effect of system mass on the impact parameter dependence of N/Z dependence of balance energy. The study shows that lighter systems shows greater sensitivity to colliding geometry towards the N/Z dependence.

Role of isospin degree of freedom on the mass dependence of balance energy
The effect of isospin degree of freedom on balance energy and its mass dependence has been studied for the mass range between 50 and 350. Our results shows the dominance of Coulomb potential in isospin effects.

On the study of momentum correlations in fragmentation in heavy-ion collisions
The role of momentum correlations in fragmentation is studied within the framework of quantum molecular dynamics model. Our study is carried out by imposing momentum cut in the clusterization algorithm. The study reveals a strong effect of momentum cut in the fragmentation pattern. A comparison with experimental data is also presented. Our theoretical results are in agreement with the experimental data.

Model-independent study of light-cone current commutators
An attempt is made to extract information on the nature of light-cone current commutators (LCC) in a model-independent manner. Using simple assumptions on the validity of the Deser-Gilbert-Sudarshan (DGS) representation for the structure functions of deep-inelastic scattering and using the Bjorken-Johnson-Low theorem we show that in principle the LCC may be constructed knowing the experimental electron-proton scattering data. On the other hand, the scaling behavior of the structure functions is utilized to study the consistency of a vanishing value for various LCC under mild assumptions on the behavior of the DGS spectral moments.

An Approach to Measurement in Quantum Mechanics
We consider an unconventional approach to the measurement problem in quantum mechanics — we treat the apparatus as a classical system, belonging to the macro-world.
