Analog quantum simulation of chemical dynamics
Ryan J. MacDonell, Claire E. Dickerson, Clare J. T. Birch +5
Ultrafast chemical reactions are difficult to simulate because they involve entangled, many-body wavefunctions whose computational complexity grows rapidly with molecular size. In…
Global approximation theorems for general gamma type operators
Alok Kumar
In this paper, we obtained some global approximation results for general Gamma type operators.
Voronovskaja type asymptotic approximation by general gamma type operators
Alok Kumar
In the present paper, we studied the voronovskaja type theorem for general Gamma type operators. Also, we obtain an error estimate for general Gamma type operators.
Effective Action and Mean Fermion Number Density of Graphene in Constant Magnetic Field at Finite Temperature and Density
Alok Kumar
The effective action and the mean fermion number density of graphene in constant external magnetic field at finite temperature and density are calculated. Closed expressions for th…
Matsubara Frequency Sums
Alok Kumar
We cannot use directly the results of zero-temperature at finite temperature, for at finite temperature the average is to be carried over all highly degenerate excited states unlik…
Covariant and Contravariant Vectors
Alok Kumar
Vector is a physical quantity and it does not depend on any co-ordinate system. It need to be expanded in some basis for practical calculation and its components do depend on the c…
