Toroidal Dipolar Supersolid with a Rotating Weak Link
Mikael Nilsson Tengstrand, Philipp Stürmer, Johan Ribbing +1
Ring-shaped superfluids with weak links provide a perfect environment for studying persistent currents and dynamic stirring protocols. Here, we investigate the effects of a weak-li…
Supersolid Stacks in Antidipolar Bose-Einstein Condensates
Koushik Mukherjee, Mikael Nilsson Tengstrand, Tiziano Arnone Cardinale +1
We theoretically investigate a novel supersolid structure taking the form of stacked, disk-shaped superfluid droplets connected via a dilute superfluid, in an antidipolar condensat…
Mixed Bubbles in a one-dimensional Bose-Bose mixture
Philipp Stürmer, Mikael Nilsson Tengstrand, Stephanie Reimann
We investigate a Bose-Bose mixture across the miscible-immiscible phase transition governed by quantum fluctuations in one dimension. We find the recently predicted so-called mixed…
Droplet-superfluid compounds in binary bosonic mixtures
M. Nilsson Tengstrand, S. M. Reimann
While quantum fluctuations in binary mixtures of bosonic atoms with short-range interactions can lead to the formation of a self-bound droplet, for equal intra-component interactio…
Breathing mode in two-dimensional binary self-bound Bose gas droplets
Philipp Stürmer, Mikael Nilsson Tengstrand, Rashi Sachdeva +1
In this work, we present the study of the stationary structures and the breathing mode behavior of a two-dimensional self-bound binary Bose droplet. We employ an analytical approac…
Persistent Currents in Toroidal Dipolar Supersolids
M. Nilsson Tengstrand, D. Boholm, R. Sachdeva +2
We investigate the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry. Studying the ground states in the rotating frame and at fixed angular…
Self-bound supersolid stripe phase in binary Bose-Einstein condensates
Rashi Sachdeva, Mikael Nilsson Tengstrand, Stephanie M. Reimann
Supersolidity - a coexistence of superfluidity and crystalline or amorphous density variations - has been vividly debated ever since its conjecture. While the initial focus was on…
Bosonic Szilard Engine Assisted by Feshbach Resonances
J. Bengtsson, M. Nilsson Tengstrand, S. M. Reimann
It was recently found that the information-to-work conversion in a quantum Szilard engine can be increased by using a working medium of bosons with attractive interactions. In the…
Supremacy of the quantum many-body Szilard engine with attractive bosons
Jakob Bengtsson, Mikael Nilsson Tengstrand, Andreas Wacker +4
In a classic thought experiment, Szilard suggested a heat engine where a single particle, for example an atom or a molecule, is confined in a container coupled to a single heat bat…
