Localised Horizons and Holographic Thermodynamics: Supercooling in the 1/D Expansion
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze
In holography, four-dimensional confining gauge theories are often modelled by five-dimensional Einstein--scalar gravity by choosing a specific form of the scalar potential. In a l…
Abundant production of scalars and axions from phase transition bubble expansion
Isabel Garcia Garcia, Gaurang Ramakant Kane, John March-Russell +1
We revisit aspects of particle production during cosmological first-order phase transitions, and show that the expansion of true-vacuum bubbles can be a copious source of particle…
Prediction for Maximum Supercooling in SU(N) Confinement Transition
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
The thermal confinement phase transition (PT) in Yang-Mills theory is first-order for , with bounce action scaling as . Remarkably, lattice data for the actio…
Supercooled Confinement
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
We study general properties of confinement phase transitions in the early universe. An observable gravitational wave signal from such transitions requires significant supercooling.…
Chern-Simons Induced Thermal Friction on Axion Domain Walls
Saquib Hassan, Gaurang Ramakant Kane, John March-Russell +1
We study the dynamics and interactions of the solitonic domain walls that occur in realistic axion electrodynamics models including the Chern-Simons interaction, $aε_{μνλσ}F^{μν} F…
Thermality of horizon through near horizon instability: a path integral approach
Gaurang Ramakant Kane, Bibhas Ranjan Majhi
Recent investigations revealed that the near horizon Hamiltonian of a massless, chargeless outgoing particle, for its particular motion in static as well as stationary black holes,…
Entangled quantum Unruh Otto engine is more efficient
Gaurang Ramakant Kane, Bibhas Ranjan Majhi
We propose a relativistic quantum Otto cycle between an entangled state of two qubits and their composite excited (or ground) state whose efficiency can be greater than the usual s…
