Optical creation of dark-bright soliton lattices in one-dimensional multicomponent Bose-Einstein condensates
Y. Braver, D. Burba, Th. Busch +2
We present a widely accessible and experimentally realizable technique for the controlled creation of dark-bright solitons and soliton lattices in one-dimensional atomic Bose-Einst…
Second excited state of tetramer
A. Deltuva
The four-boson universality suggests the existence of the second excited tetramer state in a system of cold atoms. It is not bound but could be seen as a resonanc…
Emergent topological properties in spatially modulated sub-wavelength barrier lattices
Giedrius Žlabys, Wen-Bin He, Domantas Burba +3
We investigate topological phenomena in a spatially modulated Dirac- lattice, where the scattering potential varies periodically in space. Changing the potential modulation freq…
Two dimensional sub-wavelength topological dark state lattices
Domantas Burba, Gediminas Juzeliūnas
We present a general framework for engineering two-dimensional (2D) sub-wavelength topological optical lattices using spatially dependent atomic dark states in a -type configura…
Light-induced localized vortices in multicomponent Bose-Einstein condensates
Y. Braver, D. Burba, S. S. Nair +4
We study continuous interaction of a trapped two-component Bose-Einstein condensate with light fields in a -type configuration. Using light beams with orbital angular momentum,…
Many-body phases from effective geometrical frustration and long-range interactions in a subwavelength lattice
Domantas Burba, Gediminas Juzeliūnas, Ian B. Spielman +1
Geometrical frustration and long-range couplings are key contributors to create quantum phases with different properties throughout physics. We propose a scheme where both ingredie…
Magnetically generated spin-orbit coupling for ultracold atoms with slowly varying periodic driving
Domantas Burba, Mažena Mackoit Sinkevičienė, Viktor Novičenko +2
The spin-orbit coupling (SOC) affecting the center of mass of ultracold atoms can be simulated using a properly chosen periodic sequence of magnetic pulses. Yet such a method is ge…
Extended degenerate perturbation theory for the Floquet-Hilbert space
Yakov Braver, Egidijus Anisimovas
We consider construction of effective Hamiltonians for periodically driven interacting systems in the case of resonant driving. The standard high-frequency expansion is not expecte…
Eight-dimensional topological systems simulated using time-space crystalline structures
Yakov Braver, Egidijus Anisimovas, Krzysztof Sacha
We demonstrate the possibility of using time-space crystalline structures to simulate eight-dimensional systems based on only two physical dimensions. A suitable choice of system p…
Interference induced anisotropy in a two-dimensional dark state optical lattice
Edvinas Gvozdiovas, Ian B. Spielman, Gediminas Juzeliūnas
We describe a two-dimensional optical lattice for ultracold atoms with spatial features below the diffraction limit created by a bichromatic optical standing wave. At every point i…
Topological charge pumping with subwavelength Raman lattices
Domantas Burba, Mantas Račiūnas, Ian B. Spielman +1
Recent experiments demonstrated deeply subwavelength lattices using atoms with internal states Raman-coupled with lasers of wavelength . The resulting unit cell was i…
Two-dimensional Thouless pumping in time-space crystalline structures
Y. Braver, C. -h. Fan, G. Žlabys +2
Dynamics of particle in a resonantly driven quantum well can be interpreted as that of a particle in a crystal-like structure, with the time playing the role of the coordinate. By…
One- and two-axis squeezing via laser coupling in an atomic Fermi-Hubbard model
T. Hernández Yanes, M. Płodzień, M. Mackoit Sinkevičienė +3
We study a production of spin-squeezed states with ultra-cold atomic fermions described by the Fermi-Hubbard model in the Mott insulating phase. We show activation of two twisting…
Cold atoms meet lattice gauge theory
Monika Aidelsburger, Luca Barbiero, Alejandro Bermudez +19
The central idea of this review is to consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is…
The van der Waals interaction as the starting point for an effective field theory
Daniel Odell, Arnoldas Deltuva, Lucas Platter
We consider the system of three He atoms to assess whether a pure van der Waals potential can be used as a starting point for an effective field theory to describe three-body…
Recombination in the universal four-fermion system
A. Deltuva
In the systems of spin fermions with resonant -wave interactions supporting only weakly bound dimers the antisymmetry forbids recombination of three (or more) fermions…
Energies and widths of Efimov states in the three-boson continuum
A. Deltuva
Three-boson Efimov physics is well known in the bound-state regime, but far less in the three-particle continuum at negative two-particle scattering length where Efimov states evol…
Six-dimensional time-space crystalline structures
Giedrius Žlabys, Chu-hui Fan, Egidijus Anisimovas +1
Time crystalline structures are characterized by regularity that single-particle or many-body systems manifest in the time domain, closely resembling the spatial regularity of ordi…
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…
Localization driven superradiant instability
Honghao Yin, Jie Hu, An-Chun Ji +3
The prominent Dicke superradiant phase arises from coupling an ensemble of atoms to cavity optical field when external optical pumping exceeds a threshold strength. Here we report…
Non-Abelian geometric potentials and spin-orbit coupling for periodically driven systems
Povilas Račkauskas, Viktor Novičenko, Han Pu +1
We demonstrate the emergence of the non-Abelian geometric potentials and thus the three-dimensional (3D) spin-orbit coupling (SOC) for ultracold atoms without using the laser beams…

We propose and realize a deeply sub-wavelength optical lattice for ultracold neutral atoms using resonantly Raman-coupled internal degrees of freedom. Although counter-propagat…
