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…
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…
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 (…
Precision assessment in non-Hermitian systems: a comparative study of three formalisms
Javid Naikoo, Ravindra W. Chhajlany, Jan Kołodyński +1
Quantifying measurement precision in quantum systems is vital for advancing quantum technologies such as sensing, communication, and computation. The quantum Fisher information (QF…
Contemporary tensor network approaches to gapless and topological phases in an extended Bose-Hubbard ladder
Yuma Watanabe, Ravindra W. Chhajlany, Maciej Lewenstein +2
The development of numerically efficient computational methods has facilitated in depth studies of various correlated phases of matter including critical and topological phases. A…
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…
