Exploring light-induced phases of 2D materials in a modulated 1D quasicrystal
Yifei Bai, Anna R. Dardia, Toshihiko Shimasaki +1
Light-induced quantum phases offer the potential for simple and powerful tuning of material properties. For example, simply illuminating 2D materials in the integer quantum Hall re…
Measuring a localization phase diagram controlled by the interplay of disorder and driving
Peter Dotti, Yifei Bai, Toshihiko Shimasaki +2
The interplay of various localizing mechanisms is a central topic of modern condensed matter physics. In this work we experimentally explore the interplay between quasiperiodic dis…
Reversible phasonic control of a quantum phase transition in a quasicrystal
Toshihiko Shimasaki, Yifei Bai, H. Esat Kondakci +6
Periodic driving can tune the quasistatic properties of quantum matter. A well-known example is the dynamical modification of tunneling by an oscillating electric field. Here we sh…
Anomalous localization and multifractality in a kicked quasicrystal
Toshihiko Shimasaki, Max Prichard, H. Esat Kondakci +7
Multifractal states offer a "third way" for quantum matter, neither fully localized nor ergodic, exhibiting singular continuous spectra, self-similar wavefunctions, and transport a…
Interaction-driven breakdown of dynamical localization in a kicked quantum gas
Alec Cao, Roshan Sajjad, Hector Mas +7
Quantum interference can terminate energy growth in a continually kicked system, via a single-particle ergodicity-breaking mechanism known as dynamical localization. The effect of…
Transport controlled by Poincaré orbit topology in a driven inhomogeneous lattice gas
Alec Cao, Roshan Sajjad, Ethan Q. Simmons +3
In periodic quantum systems which are both homogeneously tilted and driven, the interplay between drive and Bloch oscillations controls transport dynamics. Using a quantum gas in a…
Phasonic Spectroscopy of a Quantum Gas in a Quasicrystalline Lattice
Shankari V. Rajagopal, Toshihiko Shimasaki, Peter Dotti +5
Phasonic degrees of freedom are unique to quasiperiodic structures, and play a central role in poorly-understood properties of quasicrystals from excitation spectra to wavefunction…
Injection-locking of a fiber-pigtailed laser to an external cavity diode laser via fiber optic circulator
Toshihiko Shimasaki, Eustace R. Edwards, David DeMille
We report a simple tunable master-slave laser injection-lock scheme for atomic physics experiments. Seed light from an external cavity diode laser is injected into a high-power fib…
Quantifying and controlling prethermal nonergodicity in interacting Floquet matter
Kevin Singh, Cora J. Fujiwara, Zachary A. Geiger +10
The use of periodic driving for synthesizing many-body quantum states depends crucially on the existence of a prethermal regime, which exhibits drive-tunable properties while fores…
Observation and uses of position-space Bloch oscillations in an ultracold gas
Zachary A. Geiger, Kurt M. Fujiwara, Kevin Singh +8
We report the direct observation and characterization of position-space Bloch oscillations using an ultracold gas in a tilted optical lattice. While Bloch oscillations in momentum…
Continuous Production of Rovibronic Ground State RbCs Molecules via Short-Range Photoassociation to the States
Toshihiko Shimasaki, Jin-Tae Kim, Yuqi Zhu +1
We have investigated rovibronic levels of the strongly mixed states [the 2(1), 3(1), and 4(1) states in Hund's case (c) notation] of RbCs in…
Experimental Realization of a Relativistic Harmonic Oscillator
Kurt M. Fujiwara, Zachary A. Geiger, Kevin Singh +5
We report the experimental study of a harmonic oscillator in the relativistic regime. The oscillator is composed of Bose-condensed lithium atoms in the third band of an optical lat…
Quantum Simulation of Ultrafast Dynamics Using Trapped Ultracold Atoms
Ruwan Senaratne, Shankari V. Rajagopal, Toshihiko Shimasaki +5
Ultrafast electronic dynamics are typically studied using pulsed lasers. We demonstrate a complementary experimental approach: quantum simulation of ultrafast dynamics using trappe…
Production of rovibronic ground state RbCs molecules via two-photon cascade decay
Toshihiko Shimasaki, Michael Bellos, C. D. Bruzewicz +2
We report the production of ultracold RbCs molecules in the rovibronic ground state, i.e., , by short-range photoassociation to the state followed by…
Continuous Formation of Vibronic Ground State RbCs Molecules via Photoassociation
C. D. Bruzewicz, Mattias Gustavsson, Toshihiko Shimasaki +1
We demonstrate the direct formation of vibronic ground state RbCs molecules by photoassociation of ultracold atoms followed by radiative stabilization. The photoassociation proceed…
