Dynamical Signatures and Kibble-Zurek Scaling of Localization in Tilted Bose-Einstein Condensates
Argha Debnath, Radheshyam Saha, Ravindra W. Chhajlany +2
We study nonequilibrium signatures of tilt-induced localization in a one-dimensional Bose-Einstein condensate loaded in a shallow optical lattice. The tilt strength acts as a contr…
Precision assessment in non-Hermitian systems: a comparative study of three formalisms
Javid Naikoo, Ravindra W. Chhajlany, Jan KoÅodyÅski +1
Quantifying measurement precision in quantum systems is vital for advancing quantum technologies such as sensing, communication, and computation. The quantum Fisher information (QF…
A Hybrid Anyon-Otto thermal machine
Mohit Lal Bera, Joyce Kwan, Armando Pérez +6
We propose a four-stroke quantum thermal machine based on the 1D anyon Hubbard model, which is capable of extracting the excess energy arising from anyon exclusion statistics at lo…
Revealing the anisotropic charge-density-wave order of TiSe through high harmonic generation
Lin Zhang, Igor Tyulnev, Lenard Vamos +6
Titanium diselenide (TiSe) is a transition-metal dichalcogenide material that undergoes a charge-density-wave (CDW) transition at . In a recent…
Anomalous fluctuations of Bose-Einstein condensates in optical lattices
Zahra Jalali-Mola, Niklas Käming, Luca Asteria +6
Fluctuations are fundamental in physics and important for understanding and characterizing phase transitions. In this spirit, the phase transition to the Bose-Einstein condensate (…
Enhanced quantum sensing with hybrid exceptional-diabolic singularities
Javid Naikoo, Ravindra W. Chhajlany, Adam Miranowicz
We report an enhanced sensitivity for detecting linear perturbations near hybrid (doubly degenerated) exceptional-diabolic (HED) singular points in a four mode bosonic system. The…
