Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Periodic homogenisation for $\phi^4_2$
周期均匀化 \phi^4_2 奇异SPDE
2023/5/10
We consider a periodic homogenisation problem for $\phi^4_2$, a toy model that combines both renormalisation in singular SPDEs and homogenisation. In this case, we show that two different orders of th...

2012/4/27
In this paper, we present a study on how to develop an efficient multiscale simulation strategy for the dynamics of chemically active systems on low-dimensional supports. Such reactions are encountere...
Dynamical Magnetic and Nuclear Polarization in Complex Spin Systems: Semi-magnetic II-VI Quantum Dots
Dynamical Magnetic Nuclear Polarization Complex Spin Systems Semi-magnetic II-VI Quantum Dots
2012/2/29
Dynamical magnetic and nuclear polarization in complex spin systems is discussed on the example of transfer of spin from exciton to the central spin of magnetic impurity in a quantum dot in the presen...

2011/8/29
We describe an implementation to solve Poisson’s equation for an isolated system on a unigrid mesh using FFTs. The method solves the equation globally on mesh blocks distributed across multiple proces...
Overlapping fragments method for electronic structure calculation of large systems
fragments method electronic structure calculation of large systems
2010/11/25
We present a method for the calculation of electronic structure of systems that contain tens of
thousands of atoms. The method is based on the division of the system into mutually overlapping
fragme...
Fermion- and spin-counting in strongly correlated systems in and out of thermal equilibrium
Fermion spin-counting correlated systems equilibrium
2010/11/8
Atom counting theory can be used to study the role of thermal noise in quantum phase transitions and to monitor the dynamics of a quantum system. We illustrate this for a strongly correlated fermionic...
Variable time amplitude amplification and a faster quantum algorithm for solving systems of linear equations
amplitude faster quantum algorithm equations
2010/11/8
We present two new quantum algorithms. Our first algorithm is a generalization of amplitude amplification to the case when parts of the quantum algorithm that is being amplified stop at different time...

Optimal bounded trigonometry control N-level quantum systems based geometrical parametrization
2010/11/5
Based on the observation that the pure states of $N-$level quantum systems can be expressed in terms of $2(N-1)$ real geometric parameters, we make full use of distinguished properties of generalized ...

Ground-state geometric quantum computation superconducting systems
2010/10/19
We propose a way to implement geometric quantum computation based on a Hamiltonian which
has a doubly degenerate ground state. Thus the system, which is steered adiabatically, remains
in the instant...

We consider an agent on a fixed but arbitrary node of a known threshold network, with the
task of detecting an unknown missing link/node. We obtain analytic formulas for the probability of success, w...
