We propose our account of the meaning of local symmetries. We argue that the general covariance principle and gauge principle both are principles of democratic epistemic access to the law of physics, leading to ontological insights about th...

We consider the observables describing spatiotemporal properties in the context of two of the most popular approaches to quantum gravity (QG), namely String Theory and Loop QG. In both approaches these observables are described by non-commu...

Of the many ways of getting at the core of the weirdnesses in quantum mechanics, there's one which traces back to Schrödinger's seminal 1935 paper, and has to do with the apparent fuzzy nature of the reality described by the formalism thro...
Dressing vs. Fixing: On How to Extract and Interpret Gauge-Invariant Content [0.03%]
Dressing与Fixing：关于如何提取和解释规范不变的内容

There is solid consensus among physicists and philosophers that, in gauge field theory, for a quantity to be physically meaningful or real, it must be gauge-invariant. Yet, every "elementary" field in the Standard Model of particle physics ...

If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future accor...
Quantum Reconstructions as Stepping Stones Toward ψ-Doxastic Interpretations? [0.03%]
量子重构作为走向ψ-doxygen诠释的踏脚石？

In quantum foundations, there is growing interest in the program of reconstructing the quantum formalism from clear physical principles. These reconstructions are formulated in an operational framework, deriving the formalism from informati...
Pointillisme à la Signac and Construction of a Quantum Fiber Bundle Over Convex Bodies [0.03%]

We use the notion of polar duality from convex geometry and the theory of Lagrangian planes from symplectic geometry to construct a fiber bundle over ellipsoids that can be viewed as a quantum-mechanical substitute for the classical symplec...
Edge Modes and Dressing Fields for the Newton-Cartan Quantum Hall Effect [0.03%]

It is now well-known that Newton-Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton-Cartan quantum Hall effect have been derived. However, the exist...

Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs....
