Quantum Speed Limit for States with a Bounded Energy Spectrum Open
Quantum speed limits set the maximal pace of state evolution. Two well-known limits exist for a unitary time-independent Hamiltonian: the Mandelstam-Tamm and Margolus-Levitin bounds. The former restricts the rate according to the state ene…

Absence of Heating in a Uniform Fermi Gas Created by Periodic Driving Open
Ultracold atomic gas provides a useful tool to explore many-body physics. One of the recent additions to this experimental toolbox is the Floquet engineering, where periodic modulation of the Hamiltonian allows the creation of effective po…

Observing crossover between quantum speed limits Open
We experimentally investigate quantum speed limits and their crossover in a multilevel system by fast matter wave interferometry.

Observing quantum-speed-limit crossover with matter wave interferometry Open
Quantum mechanics sets fundamental limits on how fast quantum states can be transformed in time. Two well-known quantum speed limits are the Mandelstam-Tamm (MT) and the Margolus-Levitin (ML) bounds, which relate the maximum speed of evolu…

Observation of a smooth polaron-molecule transition in a degenerate Fermi gas Open
Understanding the behavior of an impurity strongly interacting with a Fermi sea is a long-standing challenge in many-body physics. When the interactions are short-ranged, two vastly different ground states exist: a polaron quasiparticle an…

<i>In situ</i> momentum-distribution measurement of a quantum degenerate Fermi gas using Raman spectroscopy Open
The ability to directly measure the momentum distribution of quantum gases is both unique to these systems and pivotal in extracting many other important observables. Here we use Raman transitions to measure the momentum distribution of a …

High-Sensitivity rf Spectroscopy of a Strongly Interacting Fermi Gas Open
rf spectroscopy is one of the most powerful probing techniques in the field of ultracold gases. We report on a novel rf spectroscopy scheme with which we can detect very weak signals of only a few atoms. Using this method, we extended the …

Realistic shortcuts to adiabaticity in optical transfer Open
Shortcuts to adiabaticity (STA) are techniques allowing rapid variation of\nthe system Hamiltonian without inducing excess heating. Fast optical transfer\nof atoms between different locations is a prime example of an STA application.\nWe s…

Derivative Based Focal Plane Array Nonuniformity Correction Open
This paper presents a fast and robust method for fixed pattern noise nonuniformity correction of infrared focal plane arrays. The proposed method requires neither shutter nor elaborate calibrations and therefore enables a real time correct…
