Low frequency gray-body factors and infrared divergences: rigorous results
, 2015 Formal solutions to the mode equations for both spherically symmetric black holes and Bose-Einstein condensate acoustic black holes are obtained by writing the spatial part of the mode equation as a linear Volterra integral equation of the second kind ...

Dynamics of Vector Soliton Singlets and Pairs in Self‐Mode‐Locked Tm‐Doped Fibre Lasers
Laser &Photonics Reviews, EarlyView.This study characterises soliton build‐up dynamics in a self‐mode‐locked Tm‐doped fibre laser, where both cavity birefringence and distributed saturable absorber play significant roles in the intracavity pulse shaping. The recorded single‐shot spectra using the dispersive Fourier transform technique reveal intensity‐dependent temporal splitting of ...

Stability control in a helicoidal spin–orbit-coupled open Bose–Bose mixture
Open Physics, 2023 In this article, the modulation instability (MI) of open Bose–Bose mixtures with helicoidal spin–orbit coupling (SOC) was studied. Unlike previous spin–orbit (SO)-coupled Bose–Einstein condensate system with helicoidal gauge potential, the purpose of ...

Detection of acceleration radiation in a Bose-Einstein condensate [PDF]
, 2007 We propose and study methods for detecting the Unruh effect in a Bose-Einstein condensate. The Bogoliubov vacuum of a Bose-Einstein condensate is used here to simulate a scalar field-theory, and accelerated atom dots or optical lattices as means for ...

Laser &Photonics Reviews, EarlyView.Simultaneous temporal soliton self‐compression with simultaneous formation of a radial Townes profile is reported for millijoule pulses at 4.9 µm wavelength in ZnS. Pulses as short as 37 fs are generated in a 1‐kHz pulse train. The compression regime appears below the onset of filamentation, yielding two‐cycle pulses with 2.0 mJ energy which translates

Condensate Heating by Atomic Losses
, 2003 Atomic Bose-Einstein condensate is heated by atomic losses. Predicted depletion ranges from 1% for a uniform 3D condensate to around 10% for a quasi-1D condensate in a harmonic trap.Comment: 4 pages in RevTex, 1 eps ...

Quasipure Bose-Einstein condensate immersed in a Fermi sea. [PDF]
Physical Review Letters, 2001 We report the observation of coexisting Bose-Einstein condensate (BEC) and Fermi gas in a magnetic trap. With a very small fraction of thermal atoms, the 7Li condensate is quasipure and in thermal contact with a 6Li Fermi gas.

Laser &Photonics Reviews, EarlyView.The monolayer J‐aggregate PTCDI‐C13, grown on thin hBN, is transferred to an all‐dielectric metasurface to achieve strong coupling between optical modes (GMRs and qBICs) and Frenkel excitons. With low losses in both microcavities and excitons, a Rabi splitting of 78 meV is observed in both reflectance and photoluminescence k‐space maps, enabling ...

Macroscopic Entanglement of a Bose Einstein Condensate on a Superconducting Atom Chip
, 2007 We propose and analyse a practically implementable scheme to generate macroscopic entanglement of a Bose-Einstein condensate in a micro-magnetic trap magnetically coupled to a superconducting loop.

Cavity Optomechanics with a Bose-Einstein Condensate [PDF]
Science, 2008 Cavity optomechanics studies the coupling between a mechanical oscillator and the electromagnetic field in a cavity. We report on a cavity optomechanical system in which a collective density excitation of a Bose-Einstein condensate serves as the ...
