Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The Quantum Perron-Frobenius Theorem
量子力学 Perron-Frobenius Theorem 量子对称性
2023/4/23
We establish the quantum Perron-Frobenius theorem on quantum symmtries. We characterize the structure of the Perron-Frobenius eigenvector space using quantum Fourier analysis (in the sense of picture ...
THE EQUIVALENCE THEOREM AND GLOBAL ANOMALIES
Bosons goldstein bosons current the standard model
2014/12/23
In the presence of some forms of global anomalies, the equivalence theorem, which relates the interactions of longitudinal gauge bosons to those of the Goldstone bosons, is not always valid. This can ...
Validity of the Hohenberg Theorem for a Generalized Bose-Einstein Condensation in Two Dimensions
Bose - Einstein condensation horn theorem states generalized condensation
2014/12/22
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is macroscopic, even if ...
A positive energy theorem for asymptotically de Sitter spacetimes
DE sitter spacetime conserved DE sitter universe spinor and energy
2014/12/22
We construct a set of conserved charges for asymptotically de Sitter spacetimes that correspond to asymptotic conformal isometries. The charges are given by boundary integrals at spatial infinity in t...
Bypassing the bandwidth theorem with PT symmetry
Bypassing the bandwidth theorem PT symmetry Classical Physics
2012/5/29
The beat time {\tau}_{fpt} associated with the energy transfer between two coupled oscillators is dictated by the bandwidth theorem which sets a lower bound {\tau}_{fpt}\sim 1/{\delta}{\omega}. We sho...

Uniqueness theorem for the non-local ionization source in glow discharge and hollow cathode
integro-differential operator the Fredholm 2-nd kind equation existence and uniqueness theorem nilpotency glow discharge
2012/4/19
The paper is devoted to the proof of the uniqueness theorem for solution of the equation for the non-local ionization source in a glow discharge and a hollow cathode in general 3D geometry. The theore...
Consistency of the adiabatic theorem and perturbation theory
adiabatic theorem perturbation theory Quantum Physics
2011/10/9
Abstract: We present an analysis of the adiabatic approximation to understand when it applies, in view of the recent criticisms and studies for the validity of the adiabatic theorem. We point out that...
A vanishing theorem for operators in Fock space
non-relativistic quantum electrodynamics Fock space operator theoretic renormalization symmetry
2011/9/19
Abstract: We consider the bosonic Fock space over the Hilbert space of transversal vector fields in three dimensions. This space carries a canonical representation of the group of rotations. For a cer...
Abstract: The traditional Pi-theorem tells us that for any dimensionally invariant relation there exists a full set of independent dimensionless "Pi groups" which can be used to nondimensionalise the ...
Abstract: This manuscript was originally created for and printed in the "Proceedings of seminar on unified theories of elementary particles" held in Feldafing Germany from July 5 to 16 1965 under the ...
Concavity properties prevent the existence of significant landscapes in energy surfaces obtained by energy minimizations under constraints.
Adiabatic Theorem for Discrete Time Evolution
adiabatic theorem quantum map quantum circuit Quantum Physics
2011/10/8
Abstract: A proof of the adiabatic theorem for quantum systems whose time evolution proceeds along discrete time, e.g., quantum maps and quantum circuits, is shown.
A No-Go Theorem for the Consistent Quantization of the Massive Gravitino on Robertson-Walker Spacetimes and Arbitrary Spin 3/2 Fields on General Curved Spacetimes
No-Go Theorem the Consistent Quantization the Massive Gravitino Robertson-Walker Spacetimes General Curved Spacetimes
2011/7/29
Abstract: We first introduce a set of conditions which assure that a free spin $\frac32$ field with $m\ge 0$ can be consistently ('unitarily') quantized on all curved spacetimes, i.e. also on spacetim...
No-Go theorem for energy surfaces

2011/7/28
Abstract: Concavity properties prevent the existence of significant landscapes in energy surfaces obtained by energy minimizations under constraints. The contradiction holds at finite temperatures T a...
