Quantum statistical mechanics from a Bohmian perspective
Hrvoje Nikolic
We develop a general formulation of quantum statistical mechanics in terms of probability currents that satisfy continuity equations in the multi-particle position space, for close…
Arrival time from Hamiltonian with non-hermitian boundary term
Tajron Jurić, Hrvoje Nikolić
We develop a new method for finding the quantum probability density of arrival at the detector. The evolution of the quantum state restricted to the region outside of the detector…
Passive quantum measurement: Arrival time, quantum Zeno effect and gambler's fallacy
Tajron Jurić, Hrvoje Nikolić
Classical measurements are passive, in the sense that they do not affect the physical properties of the measured system. Normally, quantum measurements are not passive in that sens…
Relativistic QFT from a Bohmian perspective: A proof of concept
Hrvoje Nikolic
Since Bohmian mechanics is explicitly nonlocal, it is widely believed that it is very hard, if not impossible, to make Bohmian mechanics compatible with relativistic quantum field…
Arrival time from the general theory of quantum time distributions
Tajron Jurić, Hrvoje Nikolić
We further develop the general theory of quantum time distributions introduced in arXiv:2010.07575 and apply it to find the distribution of arrival times at the detector. Even thou…
The time distribution of quantum events
Danijel Jurman, Hrvoje Nikolic
We develop a general theory of the time distribution of quantum events, applicable to a large class of problems such as arrival time, dwell time and tunneling time. A stopwatch tic…
Proposed measurement of simultaneous particle and wave properties of electric current in a superconductor
Hrvoje Nikolic, Josip Atelj
In a microscopic quantum system one cannot perform a simultaneous measurement of particle and wave properties. This, however, may not be true for macroscopic quantum systems. As a…
Knowledge of Quantum Hidden Variables Enables Backwards-In-Time Signaling
Avishy Carmi, Eliahu Cohen, Lorenzo Maccone +1
Bell's theorem implies that any completion of quantum mechanics which uses hidden variables (that is, preexisting values of all observables) must be nonlocal in the Einstein sense.…
Bohmian mechanics for instrumentalists
H. Nikolic
We formulate Bohmian mechanics (BM) such that the main objects of concern are macroscopic phenomena, while microscopic particle trajectories only play an auxiliary role. Such a for…
Interpretation miniatures
H. Nikolic
Most physicists do not have patience for reading long and obscure interpretation arguments and disputes. Hence, to attract attention of a wider physics community, in this paper var…
Is zero-point energy physical? A toy model for Casimir-like effect
H. Nikolic
Zero-point energy is generally known to be unphysical. Casimir effect, however, is often presented as a counterexample, giving rise to a conceptual confusion. To resolve the confus…
Internal environment: What is it like to be a Schrodinger cat?
H. Nikolic
The possibility of quantum interference of a composite object with many internal degrees of freedom is studied, such that the internal degrees play a role of an internal environmen…
Time and probability: From classical mechanics to relativistic Bohmian mechanics
H. Nikolic
Bohmian mechanics can be generalized to a relativistic theory without preferred foliation, with a price of introducing a puzzling concept of spacetime probability conserved in a sc…
How (not) to teach Lorentz covariance of the Dirac equation
H. Nikolic
In the textbook proofs of Lorentz covariance of the Dirac equation, one treats the wave function as a spinor and gamma matrices as scalars, leading to a quite complicated formalism…
Evidence for Bohmian velocities from conditional Schrodinger equation
H. Nikolic
It is often argued that measurable predictions of Bohmian mechanics cannot be distinguished from those of a theory with arbitrarily modified particle velocities satisfying the same…
Relativistic-covariant Bohmian mechanics with proper foliation
H. Nikolic
In classical relativistic mechanics, a "preferred" proper direction in spacetime for each particle is determined by the direction of its 4-momentum. Analogously, for each quantum p…
EPR before EPR: a 1930 Einstein-Bohr thought experiment revisited
H. Nikolic
In 1930 Einstein argued against consistency of the time-energy uncertainty relation by discussing a thought experiment involving a measurement of mass of the box which emitted a ph…
Solipsistic hidden variables
H. Nikolic
We argue that it is logically possible to have a sort of both reality and locality in quantum mechanics. To demonstrate this, we construct a new quantitative model of hidden variab…
Relativistic almost local hidden-variable theory
H. Nikolic
A simple relativistic quantum hidden-variable theory of particle trajectories, similar to the Bohm theory but without nonlocal forces between the particles, is proposed. To provide…
Closed timelike curves, superluminal signals, and "free will" in universal quantum mechanics
H. Nikolic
We explore some implications of the hypothesis that quantum mechanics (QM) is universal, i.e., that QM does not merely describe information accessible to observers, but that it als…
Making nonlocal reality compatible with relativity
H. Nikolic
It is often argued that hypothetic nonlocal reality responsible for nonlocal quantum correlations between entangled particles cannot be consistent with relativity. I review the mos…
Comment on "Quantum Solution to the Arrow-of-Time Dilemma"
H. Nikolic
In this paper we criticize the attempt of Maccone [Phys. Rev. Lett. 103, 080401 (2009), arXiv:0802.0438] to solve the problem of the arrow of time.
Time in relativistic and nonrelativistic quantum mechanics
H. Nikolic
The kinematic time operator can be naturally defined in relativistic and nonrelativistic quantum mechanics (QM) by treating time on an equal footing with space. The spacetime-posit…
Probability in relativistic Bohmian mechanics of particles and strings
H. Nikolic
Even though the Bohmian trajectories given by integral curves of the conserved Klein-Gordon current may involve motions backwards in time, the natural relativistic probability dens…
