Population trapping in a pair of periodically driven Rydberg atoms
S. Kumar Mallavarapu, Ankita Niranjan, Weibin Li +2
We study the population trapping extensively in a periodically driven Rydberg pair. The periodic modulation of the atom-light detuning effectively suppresses the Rabi couplings and…
Vortex structure in superfluid color-flavor locked quark matter
Mark G. Alford, S. Kumar Mallavarapu, Tanmay Vachaspati +1
The core region of a neutron star may feature quark matter in the color-flavor- locked (CFL) phase. The CFL condensate breaks the baryon number symmetry, such that the phenomenon o…
Stability of superfluid vortices in dense quark matter
Mark G. Alford, S. Kumar Mallavarapu, Tanmay Vachaspati +1
Superfluid vortices in the color-flavor-locked (CFL) phase of dense quark matter are known to be energetically disfavored relative to well-separated triplets of "semi-superfluid" c…
Role reversal in first and second sound in a relativistic superfluid
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
Relativistic superfluidity at arbitrary temperature, chemical potential and (uniform) superflow is discussed within a self-consistent field-theoretical approach. Our starting point…
From field theory to superfluid hydrodynamics of dense quark matter
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
Hydrodynamics of superfluids can be described by formally dividing the fluid into a normal fluid and a superfluid part. In color-flavor locked quark matter, at least one superfluid…
Relativistic superfluid hydrodynamics from field theory
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
It is well known that the hydrodynamics of a zero-temperature superfluid can be formulated in field-theoretic terms, relating for example the superfluid four-velocity to the gradie…
From a complex scalar field to the two-fluid picture of superfluidity
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
The hydrodynamic description of a superfluid is usually based on a two-fluid picture. We compute the basic properties of the relativistic two-fluid system from the underlying micro…
