Can Spontaneous Time-Translation Symmetry Breaking Be Quantized Without Explicit Branches?
Partha Nandi
Can classically branched dynamics associated with spontaneous time-translation-symmetry breaking be quantized without explicitly retaining the branches of the Hamiltonian? We inves…
From Analytic Structure to Quantum Complexity: Walsh-Pauli Representations of Continuum Operators
Raphael De Sousa, Partha Nandi, Francesco Petruccione
How does continuum operator structure appear in a finite qubit register? We address this question for analytic functions of diagonal operators represented in a binary basis, focusi…
Revealing the Quantum Signature of Gravity via Gravitational Waves
Partha Nandi
Can propagating gravitational waves serve as operational probes of the quantum nature of gravity? We address this question by developing a unified theoretical framework that combin…
Spin-Induced Fractal Time-Crystal-Like Dynamics and Non-Markovian Memory in the Bateman Dual Oscillator
Partha Nandi, Giuseppe Vitiello
Can a closed quantum system generate time-crystal-like nonequilibrium behavior, self-similar scaling structures, and non-Markovian memory without external driving or coupling to a…
Is Exact Markovianity Fundamental Once Time Is Relational?
Partha Nandi, Francesco Petruccione
Markovian open quantum theory assumes evolution with respect to an external classical time parameter, yet no preferred notion of time exists fundamentally in relativistic physics.…
Spin-Induced Non-Markovian Time-Crystal-Like Dynamics and Fractal Scaling in the Bateman Dual Oscillator
Partha Nandi, Giuseppe Vitiello
Can a closed quantum system generate persistent time-crystal-like dynamics without external driving? Within the Bateman dual oscillator framework, we show that the answer is affirm…
State-Selective Signatures of Quantum and Classical Gravitational Environments
Partha Nandi, Sankarshan Sahu, Bibhas Ranjan Majhi +1
A unified framework is developed for determining whether a gravitational-wave (GW) background behaves as a classical field or as a genuinely quantum environment. Unified here means…
