Abstract

After negative temperature is restated, we find that it will derive necessarily decrease of entropy. Negative temperature is based on the Kelvin scale and the condition dU>0 and dS<0. Conversely, there is also negative temperature for dU<0 and dS>0. But, negative temperature is contradiction with usual meaning of temperature and with some basic concepts of physics and mathematics. It is a question in nonequilibrium thermodynamics. We proposed a possibility of decrease of entropy due to fluctuation magnified and internal interactions in some isolated systems. From this we discuss some possible examples and theories.

A heuristic sketch how it could fit all together with time

On a scientific meta-level, it is discussed how an overall understanding of the physical universe can be built on the basis of well-proven theories, observations, and recent experiments. In the light of almost a century of struggle to make (common) sense of Quantum Mechanics and to reconcile it with General Relativity, it is proposed to (for some time) forget about quantizing gravity or striving for one Theory of Everything or 'Weltformel', which would describe the whole of reality seamlessly without any joints or suture marks. Instead of one single monolithic formalism, a three-legged compound approach is argued for. Quantum Mechanics, Relativity and Thermodynamics are proposed as the main pillars of reality, each with its well-defined realm, specific features, and clearly marked interfaces between the three of them. Not only classical reality, which is rather directly accessible to us, is then comprehensively modelled by their encompassing combination. Quantum phenomena are understood as undoubtedly lying at the bottom of classical physics and at the same time, they become 'fully real' only when embedded in classical frames, i.e., preparation and measurements in time. It is then where thermodynamics steps in and provides the mediating glue as it does at interfaces towards gravity. Decoherence is understood as a smooth way of gradually transferring information and basically dumping entropy to a suitable environment. The aim of this short contribution is not to deliver novel quantitative results but rather to propose a comprehensive research program and to coarsely lay out a very roughly coherent sketch starting from the beginning of the one universe, which we inhabit. The all-embracing picture is claimed to be one of ('mutually induced') emergence.

Optical and magnetic penetration depths under a modified electromagnetic coupling in charged bosonic condensates

We establish the relation between optical condensate spectral weight and static magnetic screening in a proposed effective theory of charged bosonic condensates with an additional diamagnetic coupling. Starting from an explicit Ginzburg--Landau functional, we derive both the London equation and the transverse low-frequency conductivity. At fixed condensate parameter $q^2n_s/m^\ast$, the modified coupling doubles the inverse-square magnetic screening length and the optical condensate weight, giving $λ_{\rm mag}=λ_{\rm stiff}=λ_L/\sqrt{2}$, where $λ_L^{-2}=μ_0q^2n_s/m^\ast$. Their ratio is therefore unity in both the standard and modified local theories: it tests consistency between measurement methods but cannot distinguish the couplings. A structured comparison of published results for Nb, Pb, YBCO, MgB$_2$, and Ba(Fe,Co)$_2$As$_2$ identifies the roles of sample matching, absolute calibration, nonlocality, and spectral-weight extraction. We formulate the requirements for a discriminating absolute-response experiment and discuss a complementary single-particle spectral prediction. The analysis separates experimentally accessible consistency checks from tests requiring independent information about condensate parameters or a different observable.

Autocatalytic order controls bistability in a conservative kinetic model of relational event progression

This version supersedes earlier versions and develops the three-class model of v1 into a closed, conserved network. On a relational view, the Universe is the happening of events rather than a container for them. A kinetic model gives this dynamical form: events are sorted as future, now or past; future events combine reversibly into now events; a now event meeting past events is activated and completes irreversibly into past events, which are renewed for future use. Past events thus catalyse their own production in a closed network conserving a weighted event count. We give a complete mass-action and bifurcation analysis. Conservation fixes the stoichiometry uniquely. When one past event participates in each activation, progression ignites softly at a transcritical threshold and no fold can arise, for every completion yield. When two participate cooperatively, the progressing branch folds: a past-rich attractor coexists with a past-poor state and ignition needs a finite perturbation. Cooperative order creates memory; nonequilibrium asymmetry only sets how hard it is to undo, strict one-way latching being a singular limit of hysteresis. In a partially reversible network where only renewal is reversible, two stable interior states coexist while activation and completion stay strictly one-way. The work is theoretical and does not derive time or its arrow: relational ordering and local irreversibility are assumed. As stated postulates, events are parcels of energy, the budget is conserved energy, and the activated class is the activated complex of transition-state theory. Around each cycle both the budget and the event number are conserved; at steady state the composition is stationary while energy is concentrated and dispersed locally, and whether entropy production vanishes globally is posed as a hypothesis.
