ProtectiveMeasurements and Quantum Reality: Toward a New Understandingof Quantum Mechanics 保护性测量与量子实在
2015/4/20
2015年1月，中国科学院自然科学史研究所副研究员高山主编的英文论文集《保护性测量与量子实在》由剑桥大学出版社出版。该论文集是为纪念1993 年Yakir Aharonov，Lev Vaidman和Jeeva Anandan发现的一种新的量子测量方法——“保护性测量”距今20周年而做。利用“保护性测量”这种方法，可以直接测量出单个量子系统的波函数，对保护性测量的哲学分析可能会导致量子力学的一种新的...
Bose-Einstein condensation, fluctuations, and recurrence relations in statistical mechanics
Gas bose Einstein condensation partition function condensation
2014/12/20
We calculate certain features of Bose–Einstein condensation in the ideal gas by using recurrence relations for the partition function. The grand canonical ensemble gives inaccurate results for certain...
Enthalpy and the mechanics of AdS black holes
Geometric Smarr formula of static black hole the first law the cosmological constant
2014/12/19
We present geometric derivations of the Smarr formula for static AdS black holes and an expanded first law that includes variations in the cosmological constant. These two results are further related ...

On behalf of the organising committee, I am pleased to invite you to come to ISUD-9 to be held in Strasbourg.The ultrasound Doppler method has been successfully established for fluid flow measurements...
Relativistic forces in Lagangian mechanics
Relativistic forces Lagangian mechanics Mathematical Physics
2012/6/27
We give a general definition of \emph{relativistic force} in the context of Lagrangian mechanics. Once this is done we prove that the only relativistic forces which are linear on the velocities are th...
Towards a combined fractional mechanics and quantization
fractional canonical formalism Hamiltonian approach variational principles of physics nonconservative systems
2012/6/21
A fractional Hamiltonian formalism is introduced for the recent combined fractional calculus of variations. The Hamilton-Jacobi partial differential equation is generalized to be applicable for system...

Contradiction of the DENSITY MATRIX notion in quantum mechanics
Contradiction of the DENSITY MATRIX notion quantum mechanics General Physics
2012/4/19
It is shown that description of a nonpolarized neutron beam by density matrix is contradictory. Density matrix is invariant with respect to choice of quantization axis, while experimental devices can ...
Derivation of the Schrodinger equation from the Hamilton-Jacobi equation in Feynman's path integral formulation of quantum mechanics
Derivation of the Schrodinger equation Hamilton-Jacobi equation Feynman's path integral formulation of quantum mechanics
2012/4/19
It is shown how the time-dependent Schr\"{o}dinger equation may be simply derived from the dynamical postulate of Feynman's path integral formulation of quantum mechanics and the Hamilton-Jacobi equat...
Quantum Mechanics versus Special Relativity: A forgotten conflict
quantum mechanics special relativity quantum collapse quantum entanglement space-time causation separability locality non-locality asymptotic independence
2011/9/6
Despite the widespread assumptions on the compatibility between non-relativistic quantum mechanics and special relativity, there still remains a considerable amount of unresolved problems to which few...
Supersymmetric Quantum Mechanics with Reflections

2011/9/22
Abstract: We consider a realization of supersymmetric quantum mechanics where supercharges are differential-difference operators with reflections. A supersymmetric system with an extended Scarf I pote...
Relativistic Quantum and Classical Mechanics in the Hilbert Space
Relativistic Quantum Classical Mechanics the Hilbert Space
2011/8/18
Abstract: We present a formulation of relativistic classical and quantum mechanics in the Hilbert space with a linkage through the Ehrenfest quantization. We start with the covariant form of the Loren...
A Euclidean formulation of relativistic quantum mechanics

2011/7/20
In this paper we discuss a formulation of relativistic quantum mechanics that uses Euclidean Green functions or generating functionals as input.

Abstract: This paper appeared in a collection of papers titled "Scientific Papers Presented to Max Born on his retirement from the Tait Chair of Natural Philosophy in the University of Edinburgh", pub...
Abstract: We construct the manifestly N=4 supersymmetric off-shell superfield "master" action for any number n of the N=4 supermultiplets (4, 4, 0) described by harmonic analytic superfields q^{+a}(\z...
