Non-hermitian models in higher dimensions
Pulak Ranjan Giri
It is know that PT-symmetric models have real spectra provided the symmetry is not spontaneously broken. Even pseudo-hermitian models have real spectra, which enlarge the the class…
Localization at threshold in noncommutative space
Pulak Ranjan Giri
The ground state energy of a scale symmetric system usually does not possess any lower bound, thus making the system quantum mechanically unstable. Self-adjointness and renormaliza…
Quantization of neutron in Earth's gravity
Pulak Ranjan Giri
Gravity is the weakest of all four known forces in the universe. Quantum states of an elementary particle due to such a weak field is certainly very shallow and would therefore be…
Optimal time evolution in (non)hermitian quantum mechanics

Scaling anomaly in cosmic string background
Pulak Ranjan Giri
We show that the classical scale symmetry of a particle moving in cosmic string background is broken upon inequivalent quantization of the classical system, leading to anomaly. The…
Dipole binding in a cosmic string background due to quantum anomalies
Pulak Ranjan Giri
We propose quantum dynamics for the dipole moving in cosmic string background and show that the classical scale symmetry of a particle moving in cosmic string background is still r…
