Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

The main power of quantum sensors is achieved when the probe is composed of several
particles. In this situation, quantum features such as entanglement contribute in enhancing …

Floquet dynamical quantum phase transitions (FDQPTs) are signified by recurrent
nonanalytic behaviors of observables in time. In this work, we introduce a quench-free and …

The nonequilibrium dynamics of long-range pairing Kitaev model with noiseless/noisy linear
time dependent chemical potential, is investigated in the framework of dynamical quantum …

The nonequilibrium dynamics of a periodically driven extended XY model, in the presence of
linear time dependent magnetic field, is investigated using the notion of dynamical quantum …

An interacting spin system is an excellent testbed for fundamental quantum physics and

Dynamical quantum phase transition is a critical phenomenon involving out-of-equilibrium
states and broken symmetries without classical analogy. However, when finite-sized …

Quantum critical systems offer promising advancements in quantum sensing and metrology,
yet face limitations like critical slowing down and a restricted criticality-enhanced region …

We uncover a novel dynamical quantum phase transition, using random matrix theory and
its associated notion of planar limit. We study it for the isotropic XY Heisenberg spin chain …

The rapidly emerging quantum technologies are expected to revolutionize our lives in the
coming decades [1]. In a broad sense, quantum technologies are developed in three …
