Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Energy/dissipation-preserving split Birkhoffian multi-symplectic methods for Maxwell’s equations
麦克斯韦方程组 能量/耗散守恒分裂 Birkhofian 多辛方法
2023/5/18
We propose a novel kind of energy/dissipation-preserving split Birkhoffian multi-symplectic (S-BMS) methods for Maxwell's equations with dissipation terms. After investigating the non-autonomous and a...
Scientists at Yale University have confirmed a 50-year-old, previously untested theoretical prediction in physics and improved the energy storage time of a quantum switch by several orders of magnitud...
A Fast Numerical Scheme for Causal Relativistic Hydrodynamics with Dissipation
Relativistic Hydrodynamics
2011/7/21
In this paper, we develop a stable and fast numerical scheme for relativistic dissipative hydrodynamics based on Israel-Stewart theory.
Dissipation evidence for the quantum damped harmonic oscillator via pseudo-bosons

2011/7/26
Abstract: It is known that a self-adjoint, time-independent hamiltonian can be defined for the quantum damped harmonic oscillator. We show here that the two vacua naturally associated to this operator...
Inertial forces and dissipation on accelerated boundaries
High Energy Physics-Theory(hep-th) Quantum Physics(quant-ph)
2010/11/9
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees ...
Magnetization Dynamics, Bennett Clocking and Associated Energy Dissipation in Multiferroic Logic
Nanomagnetic logic arrays and nanocomputing multiferroics Bennett clocking
2010/11/22
It has been recently shown that multiferroic logic – where logic bits are encoded in the magnetization orientation of a nanoscale magnetostrictive layer elastically coupled to a piezoelectric layer – ...
Structures of nonequilibrium fluctuations: dissipation and activity
Structures of nonequilibrium fluctuations dissipation activity
2010/11/24
We discuss research done in two important areas of nonequilibrium statistical mechanics: fluctuation dissipation relations and dynamical fluctuations. The work discussed here was reported before in [2...
Generalized relation between the relative entropy and dissipation for nonequilibrium systems
Generalized relation relative entropy dissipation for nonequilibrium systems
2010/11/25
Recently, Kawai, Parrondo, and Van den Broeck have related dissipation to time-reversal asymmetry. We generalized the result by considering a protocol where the physical system is driven away from an ...

2010/12/22
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees...

Quantum memories based engineered dissipation
2010/11/5
Storing quantum information for long times without disruptions is a major requirement for most quantum information technologies. A very appealing approach is to use self-correcting Hamiltonians, i.e. ...

Deterministic creation stationary entangled states dissipation
2010/10/21
We propose a practical physical system for creation of a stationary entanglement by dissipation without employing the environment engineering techniques. The system proposed is composed of two perfect...
Dynamics of a qutrit dissipation model: non-Markovian quantum trajectory approach
Dynamics qutrit dissipation model non-Markovian quantum trajectory approach
2010/10/21
The non-Markovian dynamics of a qutrit system coupled to a bosonic environment is a difficult
problem due to the lack of an exact master equation. We present for the first time an exact
non-Markovia...
Disentanglement and Decoherence without dissipation at non-zero temperatures
Disentanglement Decoherence without dissipation non-zero temperatures
2010/10/20
Decoherence is well understood, in contrast to disentanglement. According to common lore, irre-
versible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show...

This paper, the second in a series (the first one appearing as arXiv:1001.2489), continues our investigations of a two-oscillator sys-tem in linear relative motion serving as a simplified model of the...
