Drag-induced dynamical formation of dark solitons in Bose mixture on a ring
Andrzej Syrwid, Emil Blomquist, Egor Babaev
Andreev-Bashkin drag plays a very important role in multiple areas like superfluid mixtures, superconductors and dense nuclear matter. Here, we point out that the drag phenomenon c…
Can a bright soliton model reveal a genuine time crystal for a finite number of bosons?
Andrzej Syrwid, Arkadiusz Kosior, Krzysztof Sacha
We analyze time crystal effects in a finite system of bosons which form a bright soliton clump on the Aharonov-Bohm ring. In the large particle number limit, ,…
Borromean supercounterfluidity
Emil Blomquist, Andrzej Syrwid, Egor Babaev
We demonstrate microscopically the existence of a new superfluid state of matter in a three-component Bose mixture trapped in an optical lattice. The superfluid transport involving…
Repulsive dynamics of strongly attractive one-dimensional quantum gases
Maciej Łebek, Andrzej Syrwid, Piotr T. Grochowski +1
We analyze the dynamics of one-dimensional quantum gases with strongly attractive contact interactions. We specify a class of initial states for which attractive forces effectively…
Many-body molecule formation at a domain wall in a one-dimensional strongly interacting ultracold Fermi gas
Andrzej Syrwid, Maciej Łebek, Piotr T. Grochowski +1
We analyze how the presence of the bound state on top of strong intercomponent contact repulsion affects the dynamics of a two-component ultracold Fermi gas confined in a one-dimen…
Dissipationless Vector Drag--Superfluid Spin Hall Effect
Andrzej Syrwid, Emil Blomquist, Egor Babaev
Dissipationless flows in single-component superfluids have a significant degree of universality. In He4, the dissipationless mass flow occurs with a superfluid velocity determined…
Response to comment on "Lack of a genuine time crystal in a chiral soliton model" by Öhberg and Wright
Andrzej Syrwid, Arkadiusz Kosior, Krzysztof Sacha
In the paper [Phys. Rev. Research 2, 032038] we have analyzed a chiral soliton model and shown that despite the claim of Öhberg and Wright [Phys. Rev. Lett. 124, 178902], there is…
Quantum dark solitons in ultracold one-dimensional Bose and Fermi gases
Andrzej Syrwid
Solitons are ubiquitous phenomena that appear, among others, in the description of tsunami waves, fiber-optic communication and ultracold atomic gases. The latter systems turned ou…
Measurement of one-dimensional matter-wave quantum breather
Piotr Staroń, Andrzej Syrwid, Krzysztof Sacha
Employing the Bethe ansatz approach and numerical simulations of measurements of particles' positions we investigate a post-quench many-body dynamics of attractively interacting bo…
Lack of a genuine time crystal in a chiral soliton model
Andrzej Syrwid, Arkadiusz Kosior, Krzysztof Sacha
In a recent publication [Phys. Rev. Lett. {\bf 124}, 178902] Öhberg and Wright claim that in a chiral soliton model it is possible to realize a genuine time crystal which correspon…
Comment on "Quantum Time Crystals and Interacting Gauge Theories in Atomic Bose-Einstein Condensates"
Andrzej Syrwid, Arkadiusz Kosior, Krzysztof Sacha
In a recent letter [Phys. Rev. Lett. 123, 250402], Öhberg and Wright describe a Bose-Einstein condensate trapped on a ring in the presence of the density-dependent gauge potential.…
Dynamical quantum phase transitions in systems with broken continuous time and space translation symmetries
Arkadiusz Kosior, Andrzej Syrwid, Krzysztof Sacha
Spontaneous breaking of continuous time translation symmetry into a discrete one is related to time crystal formation. While the phenomenon is not possible in the ground state of a…
Emergence of dark soliton signatures in a one-dimensional unpolarized attractive Fermi gas on a ring
Andrzej Syrwid, Dominique Delande, Krzysztof Sacha
The two-component Fermi gas with contact attractive interactions between different spin components can be described by the Yang-Gaudin model. Applying the Bethe ansatz approach, on…
Quantum dark solitons in Bose gas confined in a hard wall box
Andrzej Syrwid, Krzysztof Sacha
Schrödinger equation for Bose gas with repulsive contact interactions in one-dimensional space may be solved analytically with the help of the Bethe ansatz if we impose periodic bo…
Single-shot simulations of dynamics of quantum dark solitons
Andrzej Syrwid, Mirosław Brewczyk, Mariusz Gajda +1
Eigenstates of Bose particles with repulsive contact interactions in one-dimensional space with periodic boundary conditions can be found with the help of the Bethe ansatz. The typ…
Lieb-Liniger model: emergence of dark solitons in the course of measurements of particle positions
Andrzej Syrwid, Krzysztof Sacha
Lieb-Liniger model describes bosons with contact interactions in one-dimensional space. In the limit of weak repulsive particle interactions, there are two types of low lying excit…
