Classical Mechanics on Finite Spaces
Kaustav Giri, V. V. Sreedhar
The connection between topology and quantum mechanics is one of the cornerstones of modern physics. Several examples of current interest like the Aharonov-Bohm effect in quantum me…
An Open Quantum System of Coupled Rotors
V V Sreedhar, Ankit Yadav
A quantum mechanical system of two coupled rotors (particles constrained to move on a circle) is studied from an open quantum systems point of view. One of the rotors is integrated…
The Anyonic Quantum Carnot Engine
H S Mani, N Ramadas, V V Sreedhar
Combining two disparate lines of thought like thermodynamics and quantum mechanics yields surprising results. The resulting idea of quantum thermodynamic engines holds promise for…
Dirac Brackets Lindblad Equation: A Correspondence
Aleek Maity, V V Sreedhar
The time evolution of an open quantum system is governed by the Gorini-Kossakowski-Sudarshan-Lindlad equation for the reduced density operator of the system. This operator is obtai…
Quantum Thermodynamics of Small Systems: The Anyonic Otto Engine
H S Mani, Ramadas N, V V Sreedhar
Recent advances in applying thermodynamic ideas to quantum systems have raised the novel prospect of using non-thermal, non-classical sources of energy, of purely quantum origin, l…
Quantum entanglement of anyon composites
V V Sreedhar, N Ramadas
Studying quantum entanglement in systems of indistinguishable particles, in particular anyons, poses subtle challenges. Here, we investigate a model of one-dimensional anyons defin…
Quantum Entanglement in the One-Dimensional Anyonic Hubbard Model
Ramadas N, V V Sreedhar
Issues related to quantum entanglement in systems of indistinguishable particles, as discussed in the information theoretic approach, are extended to anyonic statistics. Local and…
Quantum Entanglement In One-Dimensional Anyons
H S Mani, Ramadas N, V V Sreedhar
Anyons in one spatial dimension can be defined by correctly identifying the configuration space of indistinguishable particles and imposing Robin boundary conditions. This allows a…
The Classical and Quantum Mechanics of a Particle on a Knot
V. V. Sreedhar
A free particle is constrained to move on a knot obtained by winding around a putative torus. The classical equations of motion for this system are solved in a closed form. The exa…
A General Method for Deriving Vector Potentials Produced by Knotted Solenoids
V. V. Sreedhar
A general method for deriving exact expressions for vector potentials produced by arbitrarily knotted solenoids is presented. It consists of using simple physics ideas from magneto…
An Exact Expression for a Flat Connection on the Complement of a Torus Knot
V. V. Sreedhar
Simple physics ideas are used to derive an exact expression for a flat connection on the complement of a torus knot. The result is of some mathematical importance in the context of…
On the Topological Origin of Entanglement in Ising Spin Glasses
V. V. Sreedhar
The origin of thermal and quantum entanglement in a class of three-dimensional spin models, at low momenta, is traced to purely topological reasons. The establishment of the result…
Symmetries of Discontinuous Flows and the Dual Rankine-Hugoniot Conditions in Fluid Dynamics
Oliver Jahn, V. V. Sreedhar, Amitabh Virmani
It has recently been shown that the maximal kinematical invariance group of polytropic fluids, for smooth subsonic flows, is the semidirect product of SL(2,R) and the static Galile…
The Maximal Invariance Group of Newtons's Equations for a Free Point Particle
O. Jahn, V. V. Sreedhar
The maximal invariance group of Newton's equations for a free nonrelativistic point particle is shown to be larger than the Galilei group. It is a semi-direct product of the static…
The Maximal Kinematical Invariance Group of Fluid Dynamics and Explosion-Implosion Duality
L. O'Raifeartaigh, V. V. Sreedhar
It has recently been found that supernova explosions can be simulated in the laboratory by implosions induced in a plasma by intense lasers. A theoretical explanation is that the i…
