Coherent States with SU(2) and SU(3) Charges

Manu Mathur, Samir K. Paul

We define coherent states carrying SU(2) charges by exploiting Schwinger boson representation of SU(2) Lie algebra. These coherent states satisfy continuity property and provide re…

Information transfer in leaky atom-cavity systems

Biplab Ghosh, A. S. Majumdar, N. Nayak

We consider first a system of two enatangled cavities and a single two-level atom passing through one of them. A ``monogamy'' inequality for this tripartite system is quantitativel…

Spin dynamics in a dissipative environment: from quantal to classical

J. L. Garcia-Palacios, S. Dattagupta

We address the problem of spin dynamics in the presence of a thermal bath, by solving exactly the appropriate quantum master equations with continued-fraction methods. The crossove…

Observability of the arrival time distribution using spin-rotator as a quantum clock

Alok Kumar Pan, Md. Manirul Ali, Dipankar Home

An experimentally realizable scheme is formulated which can test any postulated quantum mechanical approach for calculating the arrival time distribution. This is specifically illu…

The Quantum-Classical Comparison of the Arrival Time Distribution through the Probability Current

Md. Manirul Ali, A. S. Majumdar, Alok Kumar Pan

We consider the arrival time distribution defined through the quantum probability current for a Gaussian wave packet representing free particles in quantum mechanics in order to ex…
