Spontaneous Collapse Theories and Temporal Primitivism about Time's Direction [0.03%]
关于时间方向的自发坍缩理论和时间原始主义

Two views on the direction of time can be distinguished-primitivism and non-primitivism. According to the former, time's direction is an in-built, fundamental property of the physical world. According to the latter, time's direction is a de...
Relational Quantum Mechanics is About Facts, Not States: A Reply to Pienaar and Brukner [0.03%]
关系量子力学是关于事实的，不是状态的：对Pienaar和Brukner的回复
Andrea Di Biagio,Carlo Rovelli
Andrea Di Biagio
In recent works, Časlav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail and show that, far from questioning the viability of the int...
Generalized Greenberger-Horne-Zeilinger Arguments from Quantum Logical Analysis [0.03%]
量子逻辑分析的广义格林伯格-霍恩-泽尔inger论据

The Greenberger-Horne-Zeilinger (GHZ) argument against noncontextual local hidden variables is recast in quantum logical terms of fundamental propositions, states and probabilities. Unlike Kochen-Specker- and Hardy-like configurations, this...

What, if anything, would be wrong with replacing the light postulate in Einstein's 1905 formulation of special relativity with a 'sound postulate', stating that the speed of sound is independent of the speed of the source? After reviewing t...

According to Relational Quantum Mechanics (RQM) the wave function ψ is considered neither a concrete physical item evolving in spacetime, nor an object representing the absolute state of a certain quantum system. In this interpretative...
Quantum Polar Duality and the Symplectic Camel: A New Geometric Approach to Quantization [0.03%]
量子极对偶性和辛骆驼：量化的一种新几何方法

We define and study the notion of quantum polarity, which is a kind of geometric Fourier transform between sets of positions and sets of momenta. Extending previous work of ours, we show that the orthogonal projections of the covariance ell...

The present essay provides a new metaphysical interpretation of Relational Quantum Mechanics (RQM) in terms of mereological bundle theory. The essential idea is to claim that a physical system in RQM can be defined as a mereological fusion ...
On the Classification Between [Formula: see text] -Ontic and [Formula: see text] -Epistemic Ontological Models [0.03%]
关于[Formula: see text]-本体和[Formula: see text]-认知本体模型的分类问题

Andrea Oldofredi
Harrigan and Spekkens (Found Phys 40:125-157, 2010) provided a categorization of quantum ontological models classifying them as ψ -ontic or ψ -epistemic if the quantum state ψ describes respectively either a physical reality ...

The causal closure of physics is usually discussed in a context free way. Here I discuss it in the context of engineering systems and biology, where strong emergence takes place due to a combination of upwards emergence and downwards causat...

The rigorous equivalence of the Schrödinger and Heisenberg pictures requires that one uses Born-Jordan quantization in place of Weyl quantization. We confirm this by showing that the much discussed " angular momentum dilemma" disappears if...
