Mechanical Squeezed-Fock Gravimeter
Rozhin Yousefjani, Saif Al-Kuwari
Levitated mechanical systems are promising candidates for quantum gravimetry, as gravity couples directly to their center-of-mass motion, enabling the large mass of a mesoscopic pa…
Nonlinearity-enhanced Quantum Sensing in Discrete Time Crystal Probes
Rozhin Yousefjani, Shaikha Al-Naimi, Saif Al-Kuwari +1
Discrete time crystals are non-equilibrium phases of matter in periodically driven systems, characterized by robust subharmonic oscillations and broken discrete time-translation sy…
Exponentially-enhanced Weak-field Sensing with Quantum Stark Localization
Rozhin Yousefjani, Saif Al-Kuwari
Stark-localized quantum probes have recently been shown to enable quantum-enhanced weak-field sensing with polynomial or super-polynomial scaling. In this paper, we show that the s…
Thermal avalanches in isolated many-body localized systems
Muhammad Sajid, Rozhin Yousefjani, Abolfazl Bayat
Many-body localization is a profound phase of matter affecting the entire spectrum which emerges in the presence of disorder in interacting many-body systems. Recently, the stabili…
Discrete time crystal for periodic-field sensing with quantum-enhanced precision
Rozhin Yousefjani, Saif Al-Kuwari, Abolfazl Bayat
Sensing periodic-fields using quantum sensors has been an active field of research. In many of these scenarios, the quantum state of the probe is flipped regularly by the applicati…

Victor Montenegro, Chiranjib Mukhopadhyay, Rozhin Yousefjani +4
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 to enhancing the…
Discrete Time Crystal Phase as a Resource for Quantum Enhanced Sensing
Rozhin Yousefjani, Krzysztof Sacha, Abolfazl Bayat
Discrete time crystals are a special phase of matter in which time translational symmetry is broken through a periodic driving pulse. Here, we first propose and characterize an eff…
Nonlinearity-enhanced quantum sensing in Stark probes

Stark systems in which a linear gradient field is applied across a many-body system have recently been proposed for quantum sensing. Here, we explore sensing capacity of Stark prob…
Long-range interacting Stark many-body probes with Super-Heisenberg precision
Rozhin Yousefjani, Xingjian He, Abolfazl Bayat
In contrast to interferometry-based quantum sensing, where interparticle interaction is detrimental, quantum many-body probes exploit such interactions to achieve quantum-enhanced…
Stark localization as a resource for weak-field sensing with super-Heisenberg precision
Xingjian He, Rozhin Yousefjani, Abolfazl Bayat
Gradient fields can effectively suppress particle tunneling in a lattice and localize the wave function at all energy scales, a phenomenon known as Stark localization. Here, we sho…
Mobility edge in long-range interacting many-body localized systems
Rozhin Yousefjani, Abolfazl Bayat
As disorder strength increases in quantum many-body systems a new phase of matter, the so-called anybody localization, emerges across the whole spectrum. This transition is energy…
