Quantum-classical diagnostics and Bohmian inequivalence for higher time-derivative Hamiltonians
Sanjib Dey, Andreas Fring
We develop a Bohmian analysis of a two-dimensional ghost Hamiltonian and its mapping to the degenerate Pais-Uhlenbeck model. Using Gaussian wavepackets, we derive the corresponding…
Improved coherence time of a non-Hermitian qubit in a -symmetric Environment
Duttatreya, Ipsika Mohanty, Sanjib Dey
Quantum computing's potential for exponential speedup is fundamentally limited by decoherence, a phenomenon arising from environmental interactions. Non-Hermitian quantum mechanics…
Enhanced quantum phase estimation with -deformed nonideal nonclassical light
Duttatreya, Sanjib Dey
We investigate quantum phase estimation in a Mach-Zehnder interferometer using q-deformed photon states, including q-coherent and q-cat states, which model realistic deviations fro…
Probing Planck scale effects on absolute mass limit in neutrino flavor evolution
Kartik Joshi, Sanjib Dey, Satyajit Jena
This work explores how the generalized uncertainty principle, a theoretical modification of the Heisenberg uncertainty principle inspired by quantum gravity, affects neutrino flavo…
Circuit Complexity for Coherent-Thermal States in Bosonic String Theory
Arshid Shabir, Sanjib Dey, Salman Sajad Wani +3
In this paper, we first construct thermofield double states for bosonic string theory in the light-cone gauge. We then obtain a coherent-thermal string state and a thermal-coherent…
Dynamic noncommutative BTZ black holes
Ankur, Sanjib Dey
We have studied the charged BTZ black holes in noncommutative spaces arising from two independent approaches. First, by using the Seiberg-Witten map followed by a dynamic choice of…
