1. Soliton diffusion in a Bose-Einstein condensate: A signature of the analogue Hawking radiation / Hang, Chao ; Gabadadze, Gregory ; Huang, Guoxiang
The analog Hawking radiation (HR) emanating from a sonic black hole horizon formed in a cigar-shaped Bose-Einstein condensate (BEC) at finite temperature is investigated. [...]

2. Dark energy and inflation with a volume normalized action / Gabadadze, Gregory ; Yu, Siqing
In the theories described by a volume normalized action functional, an arbitrary cosmological constant is eliminated from the physical picture of our Universe, and dynamical alternatives must be responsible for today’s accelerated expansion as well as the conjectured early-time inflation in the Universe. [...]

3. Boundary terms for massive general relativity / Gabadadze, Gregory ; Pirtskhalava, David
It is well known that the presence of a spacetime boundary requires the conventional Einstein-Hilbert action to be supplemented by the Gibbons-Hawking boundary term in order to retain the standard variational procedure. [...]

4. Medium generated gap in gravity and a 3D gauge theory / Gabadadze, Gregory ; Older, Daniel
It is well known that a physical medium that sets a Lorentz frame generates a Lorentz-breaking gap for a graviton. [...]

5. Holographic CBK relation / Gabadadze, Gregory ; Tukhashvili, Giorgi
The Crewther–Broadhurst–Kataev (CBK) relation connects the Bjorken function for deep-inelastic sum rules (or the Gross–Llewellyn Smith function) with the Adler function for electron–positron annihilation in QCD; it has been checked to hold up to four loops in perturbation theory. [...]

6. Nonlocal Galileons and self-acceleration / Gabadadze, Gregory ; Yu, Siqing
A certain class of nonlocal theories eliminates an arbitrary cosmological constant (CC) from a universe that can be perceived as our world. [...]

7. The big constant out, the small constant in / Gabadadze, Gregory
Some time ago, Tseytlin has made an original and unusual proposal for an action that eliminates an arbitrary cosmological constant. [...]
