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.

Role of isospin degree of freedom on N/Z dependence of participant-spectator matter
We study the N/Z dependence of participant-spectator matter for Ca+Ca reactions at 50 and 250MeV/nucleon. We also study the role of symmetry energy and momentum-dependent interactions on the N/Z dependence of participant-spectator matter.

Transverse in-plane flow: a new probe of symmetry energy in Fermi energy region
We study the sensitivity of transverse flow towards the different density dependence of symmetry energy in Fermi energy region. Our results show that transverse flow shows sensitivity to different density dependence of symmetry energy. The mechanism for sensitivity towards different density dependence of symmetry energy is also discussed.

Study of participant-spectator matter, thermalization and other related phenomena for neutron-rich colliding pair
We study the participant-spectator matter, density and temperature reached in heavy-ion reactions of neutron-rich systems having N/Z ratio varying from 1.0 to 2.0 at 50 and 250MeV/nucleon. Our results show a weak dependence of these quantities on the neutron content of the colliding systems. We also shed light on the role of neutron content on the thermalization achieved in a reaction.

Impact parameter dependence of the isospin effects and mass dependence of balance energy
We study the effect of isospin degree of freedom on the balance energy (Ebal) as well as its mass dependence throughout the mass range for two different sets of isobaric systems with N/Z = 1 and 1.4 at different colliding geometries ranging from the central to peripheral ones. Our findings reveal the dominance of Coulomb repulsion in isospin effects on Ebal as well as its mass dependence throughout the range of the colliding geometry. Our results also indicate that the effect of symmetry energy on the energy of vanishing flow is uniform throughout the mass range and throughout the colliding geometry.

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.

Interaction between classical and quantum systems: A new approach to quantum measurement. III. Illustration
Following the approach to quantum measurement, proposed in an earlier paper, in which the apparatus is treated as a purely classical instrument to be described by the laws of classical mechanics we examine some simple experiments for the purpose of illustration. The Stern-Gerlach experiment is examined in detail, within our approach, and we see explicitly how the relevant information is transferred to the apparatus variables. We also examine a magnetic interferometer arrangement and a crossed-field arrangement. Consideration of these experiments leads us to the inclusion of an extra procedural step in our approach. This extra step is necessary so that an observer may measure the classical apparatus variables at will after the interaction is completed.

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.
