Metastability, chaos and spectrum tomography for Bose-Hubbard rings and chains
Rajat, Doron Cohen
We analyze the metastability of Bose-Hubbard condensates for finite-size one-dimensional ring lattices and open chains, using a semiclassical tomographic perspective that emphasize…
Quantum measurement of work in mesoscopic systems
Anant Vijay Varma, Doron Cohen
Heat and work in thermodynamics refer to the measurement of changes in energy content of external bodies (baths and agents). We discuss the implications of quantum mechanics on the…
Many-body adiabatic passage: Instability, chaos, and quantum classical correspondence
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Adiabatic passage in systems of interacting bosons is substantially affected by interactions and inter-particle entanglement. We consider STIRAP-like schemes in Bose-Hubbard chains…
Tweezer interferometry with NOON states
Yehoshua Winsten, Doron Cohen, Yoav Sagi
Atomic interferometers measure phase differences along paths with exceptional precision. Tweezer interferometry represents a novel approach for this measurement by guiding particle…
Characterization of hybrid quantum eigenstates in systems with mixed classical phasespace
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Generic low-dimensional Hamiltonian systems feature a structured, mixed classical phase-space. The traditional Percival classification of quantum spectra into regular states suppor…
