Dynamical Love numbers of analogue rotating black and white holes
Satadal Datta, Wei-Can Syu, Da-Shin Lee
We calculate the dynamical tidal response coefficients (TRCs) of 2+1D analogue black and white holes generated by draining and fountaining bathtub flows, respectively. The paramete…
Regge poles of analogous rotating black holes in binary Bose-Einstein condensates: The gapped excitations
Wei-Can Syu, Tien Hsieh, Da-Shin Lee
In this paper, we study the spectrum of the Regge poles (RPs), which are the counterparts of quasinormal modes, in a draining bathtub vortex within a two-component Bose-Einstein co…
Acoustic quasibound states and tachyonic instabilities from binary Bose-Einstein condensates
Wei-Can Syu, Da-Shin Lee
We consider two-component Bose-Einstein condensates (BECs) and introduce the BEC vortex in dimensions. We focus on two types of gapped excitations induced by the modes of two…
Analogous Hawking radiation from gapped excitations in a transonic flow of binary Bose-Einstein condensates
Wei-Can Syu, Da-Shin Lee
We have studied analytically the approximate solutions to the gapped mode equations in the hydrodynamic regime for a class of binary Bose-Einstein condensate acoustic black holes.…
Analogous Hawking radiation and quantum entanglement in two-component Bose-Einstein condensates: the gapped excitations
Wei-Can Syu, Da-Shin Lee, Chi-Yong Lin
The condensates of cold atoms at zero temperature in the tunable binary Bose-Einstein condensate system are studied with the Rabi transition between atomic hyperfine states where t…
Entanglement of quantum oscillators coupled to different heat baths
Wei-Can Syu, Da-Shin Lee, Chen-Pin Yeh
We study the non-equilibrium dynamics of two coupled oscillators interacting with their own heat baths of quantum scalar fields at different temperature and with biline…
Regular and chaotic behavior of collective atomic motion in two-component Bose-Einstein condensates
Wei-Can Syu, Da-Shin Lee, Chi-Yong Lin
We theoretically study binary Bose-Einstein condensates trapped in a single-well harmonic potential to probe the dynamics of collective atomic motion. The idea is to choose tunable…
Quantum loop effects to the power spectrum of primordial perturbations during ultra slow-roll inflation
Wei-Can Syu, Da-Shin Lee, Kin-Wang Ng
We examine the quantum loop effects on the single-field inflationary models in a spatially flat Friedmann-Robertson-Walker (FRW) cosmological space-time with a general self-interac…
Analogue stochastic gravity phenomena in two-component Bose-Einstein condensates: Sound cone fluctuations
Wei-Can Syu, Da-Shin Lee, Chi-Yong Lin
We investigate the properties of the condensates of cold atoms at zero temperature in the tunable binary Bose-Einstein condensate system with a Rabi transition between atomic hyper…
